【1】Masked Audio Generation using a Single Non-Autoregressive Transformer标题:用单台非自回归Transformer产生掩蔽音频链接:https://arxiv.org/abs/2401.04577作者:Alon Ziv,Itai Gat,Gael Le Lan,Tal Remez,Felix Kreuk,Alexandre Défossez,Jade Copet,Gabriel Synnaeve,Yossi Adi摘要:我们介绍MAGNeT,一种屏蔽生成序列建模方法,直接在几个音频令牌流上操作。与以前的工作不同,MAGNeT是由一个单级,非自回归Transformer。在训练过程中,我们预测从掩码调度器获得的掩码令牌的跨度,而在推理过程中,我们使用几个解码步骤逐步构建输出序列。为了进一步提高生成的音频的质量,我们引入了一种新的重新评分方法,在该方法中,我们利用外部预训练模型对来自MAGNeT的预测进行重新评分和排名,然后将其用于后续的解码步骤。最后,我们探索了MAGNeT的混合版本,在该版本中,我们在自回归和非自回归模型之间进行融合,以自回归方式生成前几秒,而序列的其余部分则被并行解码。我们证明了MAGNeT的文本到音乐和文本到音频生成任务的效率,并进行了广泛的实证评估,同时考虑到客观指标和人类研究。所提出的方法与所评估的基线相当,同时明显更快(比自回归基线快7倍)。通过消融研究和分析,我们揭示了组成MAGNeT的每个组件的重要性,同时指出了自回归和非自回归建模之间的权衡,考虑到延迟,吞吐量和生成质量。样品可在我们的演示页面https://pages.cs.huji.ac.il/adiyoss-lab/MAGNeT上获得。摘要:We introduce MAGNeT, a masked generative sequence modeling method that operates directly over several streams of audio tokens. Unlike prior work, MAGNeT is comprised of a single-stage, non-autoregressive transformer. During training, we predict spans of masked tokens obtained from a masking scheduler, while during inference we gradually construct the output sequence using several decoding steps. To further enhance the quality of the generated audio, we introduce a novel rescoring method in which, we leverage an external pre-trained model to rescore and rank predictions from MAGNeT, which will be then used for later decoding steps. Lastly, we explore a hybrid version of MAGNeT, in which we fuse between autoregressive and non-autoregressive models to generate the first few seconds in an autoregressive manner while the rest of the sequence is being decoded in parallel. We demonstrate the efficiency of MAGNeT for the task of text-to-music and text-to-audio generation and conduct an extensive empirical evaluation, considering both objective metrics and human studies. The proposed approach is comparable to the evaluated baselines, while being significantly faster (x7 faster than the autoregressive baseline). Through ablation studies and analysis, we shed light on the importance of each of the components comprising MAGNeT, together with pointing to the trade-offs between autoregressive and non-autoregressive modeling, considering latency, throughput, and generation quality.

To further improve the reconstruction ability and pitch accuracy to enhance the editability of user-provided sound, we propose HyperGANStrument, which introduces a pitch-invariant hypernetwork to modulate the weights of a pre-trained GANStrument generator, given a one-shot sound as input. The hypernetwork modulation provides feedback for the generator in the reconstruction of the input sound. In addition, we take advantage of an adversarial fine-tuning scheme for the hypernetwork to improve the reconstruction fidelity and generation diversity of the generator. Experimental results show that the proposed model not only enhances the generation capability of GANStrument but also significantly improves the editability of synthesized sounds.

However, existing methods for video-sound generation attempt to directly create sound from visual representations, which can be challenging due to the difficulty of aligning visual representations with audio representations. In this paper, we present SonicVisionLM, a novel framework aimed at generating a wide range of sound effects by leveraging vision language models. Instead of generating audio directly from video, we use the capabilities of powerful vision language models (VLMs). When provided with a silent video, our approach first identifies events within the video using a VLM to suggest possible sounds that match the video content. This shift in approach transforms the challenging task of aligning image and audio into more well-studied sub-problems of aligning image-to-text and text-to-audio through the popular diffusion models. To improve the quality of audio recommendations with LLMs, we have collected an extensive dataset that maps text descriptions to specific sound effects and developed temporally controlled audio adapters. Our approach surpasses current state-of-the-art methods for converting video to audio, resulting in enhanced synchronization with the visuals and improved alignment between audio and video components.

However, ASR-hypothesis-based retrieval can yield poor precision if the textual hypotheses are too phonetically dissimilar to the transcript truth. In this paper, we eliminate the hypothesis-audio mismatch problem by querying the correction database directly using embeddings derived from the utterance audio; the embeddings of the utterance audio and candidate corrections are produced by multimodal speech-text embedding networks trained to place the embedding of the audio of an utterance and the embedding of its corresponding textual transcript close together. After locating an appropriate correction candidate using nearest-neighbor search, we score the candidate with its speech-text embedding distance before adding the candidate to the original n-best list. We show a relative word error rate (WER) reduction of 6% on utterances whose transcripts appear in the candidate set, without increasing WER on general utterances.【6】 FunnyNet-W: Multimodal Learning of Funny Moments in Videos in the Wild标题:FunnyNet-W:野外视频中搞笑时刻的多模式学习链接:https://arxiv.org/abs/2401.04210作者:Zhi-Song Liu,Robin Courant,Vicky Kalogeiton备注:22 pages, 14 figures摘要:自动理解有趣的时刻(即,当观看喜剧时,让人发笑的时刻是具有挑战性的,因为它们涉及到各种特征,如肢体语言,对话和文化。在本文中,我们提出了FunnyNet-W,这是一种依赖于视觉,音频和文本数据的交叉和自我注意力来预测视频中有趣时刻的模型。与大多数依赖于字幕形式的地面实况数据的方法不同,在这项工作中,我们利用了视频中自然出现的模式:(a)视频帧,因为它们包含对于场景理解必不可少的视觉信息,(b)音频,因为它包含与有趣时刻相关联的高级线索,例如语调,音高和停顿,以及(c)用语音到文本模型自动提取的文本,因为它在由大型语言模型处理时可以提供丰富的信息。为了获取标签进行训练,我们提出了一种无监督的方法,可以发现和标记有趣的音频时刻。我们提供了五个数据集上的实验:情景喜剧TBBT,MHD,MUSTARD,朋友,和TED谈话UR-Funny。大量的实验和分析表明,FunnyNet-W成功地利用视觉,听觉和文本线索来识别有趣的时刻,而我们的研究结果揭示了FunnyNet-W的预测有趣的时刻在野外的能力。FunnyNet-W在所有数据集上使用多模态线索进行有趣时刻检测,使用和不使用地面真实信息。摘要:Automatically understanding funny moments (i.e., the moments that make people laugh) when watching comedy is challenging, as they relate to various features, such as body language, dialogues and culture. In this paper, we propose FunnyNet-W, a model that relies on cross- and self-attention for visual, audio and text data to predict funny moments in videos. Unlike most methods that rely on ground truth data in the form of subtitles, in this work we exploit modalities that come naturally with videos: (a) video frames as they contain visual information indispensable for scene understanding, (b) audio as it contains higher-level cues associated with funny moments, such as intonation, pitch and pauses and (c) text automatically extracted with a speech-to-text model as it can provide rich information when processed by a Large Language Model. To acquire labels for training, we propose an unsupervised approach that spots and labels funny audio moments. We provide experiments on five datasets: the sitcoms TBBT, MHD, MUStARD, Friends, and the TED talk UR-Funny. Extensive experiments and analysis show that FunnyNet-W successfully exploits visual, auditory and textual cues to identify funny moments, while our findings reveal FunnyNet-W's ability to predict funny moments in the wild. FunnyNet-W sets the new state of the art for funny moment detection with multimodal cues on all datasets with and without using ground truth information.【7】 Efficient Selective Audio Masked Multimodal Bottleneck Transformer for Audio-Video Classification标题:用于音视频分类的高效选择性音频掩蔽多模态瓶颈Transformer链接:https://arxiv.org/abs/2401.04154作者:Wentao Zhu备注:Accepted by WACV 2024; well-formatted PDF is in this https URL arXiv admin note: text overlap with arXiv:2401.04023摘要:音频和视频是主流媒体平台中最常见的两种形式,例如,YouTube.为了有效地从多模态视频中学习,在这项工作中,我们提出了一种新的音频-视频识别方法,称为音频视频Transformer,AVT,利用视频Transformer的有效时空表示,以提高动作识别的准确性。对于多模态融合,在跨模态Transformer中简单地连接多模态标记需要大量的计算和存储资源,相反,我们通过音频-视频瓶颈Transformer来降低跨模态复杂度。为了提高多模态Transformer的学习效率,我们集成了自监督目标,即,音频-视频对比学习、音频-视频匹配和掩蔽音频和视频学习,到AVT训练中,其将不同的音频和视频表示映射到公共的多模态表示空间中。我们进一步提出了一个掩蔽的音频段损失,学习语义音频活动的AVT。在三个公共数据集和两个内部数据集上的大量实验和消融研究一致地证明了所提出的AVT的有效性。具体来说,AVT在Kinetics-Sounds上的表现比之前最先进的同类产品高出8%。AVT还通过利用音频信号,在VGGSound上超过了之前最先进的视频Transformers [25] 10%。与先前最先进的多模式方法之一MBT [32]相比,AVT在FLOP方面的效率提高了1.3%,并且在Epic-Kitchen-100上的准确性提高了3.8%。摘要:Audio and video are two most common modalities in the mainstream media platforms, e.g., YouTube. To learn from multimodal videos effectively, in this work, we propose a novel audio-video recognition approach termed audio video Transformer, AVT, leveraging the effective spatio-temporal representation by the video Transformer to improve action recognition accuracy. For multimodal fusion, simply concatenating multimodal tokens in a cross-modal Transformer requires large computational and memory resources, instead we reduce the cross-modality complexity through an audio-video bottleneck Transformer. To improve the learning efficiency of multimodal Transformer, we integrate self-supervised objectives, i.e., audio-video contrastive learning, audio-video matching, and masked audio and video learning, into AVT training, which maps diverse audio and video representations into a common multimodal representation space. We further propose a masked audio segment loss to learn semantic audio activities in AVT. Extensive experiments and ablation studies on three public datasets and two in-house datasets consistently demonstrate the effectiveness of the proposed AVT. Specifically, AVT outperforms its previous state-of-the-art counterparts on Kinetics-Sounds by 8%. AVT also surpasses one of the previous state-of-the-art video Transformers [25] by 10% on VGGSound by leveraging the audio signal. Compared to one of the previous state-of-the-art multimodal methods, MBT [32], AVT is 1.3% more efficient in terms of FLOPs and improves the accuracy by 3.8% on Epic-Kitchens-100.【8】 Cross-Speaker Encoding Network for Multi-Talker Speech Recognition标题:用于多说话人语音识别的跨话者编码网络链接:https://arxiv.org/abs/2401.04152作者:Jiawen Kang,Lingwei Meng,Mingyu Cui,Haohan Guo,Xixin Wu,Xunying Liu,Helen Meng备注:Accepted by ICASSP2024摘要:端到端的多说话人语音识别作为一种直接转录多个说话人重叠语音的有效方法已经引起了人们的极大兴趣。当前的方法通常采用1)具有分支编码器的单输入多输出(SIMO)模型,或者2)基于具有串行化输出训练(SOT)的基于注意力的编码器-解码器架构的单输入单输出(SISO)模型。在这项工作中,我们提出了一个跨扬声器编码(CSE)网络,以解决SIMO模型的限制,通过聚合跨扬声器表示。此外,CSE模型与SOT集成,以利用SIMO和SISO的优点,同时减轻它们的缺点。据我们所知,这项工作是一个早期的努力,集成SIMO和SISO多说话人语音识别。在两个说话人的LibrispeechMix数据集上的实验表明,CES模型比SIMO基线降低了8%的单词错误率(WER)。与SOT模型相比,CSE-SOT模型总体上将WER降低了10%,在高重叠语音上降低了16%。摘要:End-to-end multi-talker speech recognition has garnered great interest as an effective approach to directly transcribe overlapped speech from multiple speakers. Current methods typically adopt either 1) single-input multiple-output (SIMO) models with a branched encoder, or 2) single-input single-output (SISO) models based on attention-based encoder-decoder architecture with serialized output training (SOT). In this work, we propose a Cross-Speaker Encoding (CSE) network to address the limitations of SIMO models by aggregating cross-speaker representations. Furthermore, the CSE model is integrated with SOT to leverage both the advantages of SIMO and SISO while mitigating their drawbacks. To the best of our knowledge, this work represents an early effort to integrate SIMO and SISO for multi-talker speech recognition. Experiments on the two-speaker LibrispeechMix dataset show that the CES model reduces word error rate (WER) by 8% over the SIMO baseline. The CSE-SOT model reduces WER by 10% overall and by 16% on high-overlap speech compared to the SOT model.【9】 Zero Shot Audio to Audio Emotion Transfer With Speaker Disentanglement标题:基于说话人解缠的Zero-Shot音频情感转换链接:https://arxiv.org/abs/2401.04511作者:Soumya Dutta,Sriram Ganapathy备注:5 pages, 3 figures, accepted at ICASSP 2024摘要:音频到音频(A2A)风格转换的问题涉及用来自目标音频的风格特征替换源音频的风格特征,同时保留源音频的内容相关属性。在本文中,我们提出了一种有效的方法,称为Zero-shot情感风格转移(ZEST),允许转移的情感内容存在于给定的源音频与嵌入在目标音频,同时保留扬声器和语音内容的源。所提出的系统建立在将语音分解为语义标记、说话者表示和情感嵌入的基础上。利用这些因素,我们提出了一个框架来重建给定的语音信号的音高轮廓和训练解码器,重建语音信号。该模型使用基于重建损失的自我监督来训练。在转换期间,情感嵌入仅从目标音频导出,而其余因素从源音频导出。在我们的实验中,我们表明,即使不使用来自源或目标音频的并行训练数据或标签,我们也使用客观和主观质量评估来说明所提出的ZEST模型的zero shot情感传输能力。摘要:The problem of audio-to-audio (A2A) style transfer involves replacing the style features of the source audio with those from the target audio while preserving the content related attributes of the source audio. In this paper, we propose an efficient approach, termed as Zero-shot Emotion Style Transfer (ZEST), that allows the transfer of emotional content present in the given source audio with the one embedded in the target audio while retaining the speaker and speech content from the source. The proposed system builds upon decomposing speech into semantic tokens, speaker representations and emotion embeddings. Using these factors, we propose a framework to reconstruct the pitch contour of the given speech signal and train a decoder that reconstructs the speech signal. The model is trained using a self-supervision based reconstruction loss. During conversion, the emotion embedding is alone derived from the target audio, while rest of the factors are derived from the source audio. In our experiments, we show that, even without using parallel training data or labels from the source or target audio, we illustrate zero shot emotion transfer capabilities of the proposed ZEST model using objective and subjective quality evaluations.【10】 Class-Incremental Learning for Multi-Label Audio Classification标题:基于类增量学习的多标签音频分类方法链接:https://arxiv.org/abs/2401.04447作者:Manjunath Mulimani,Annamaria Mesaros备注:Accepted to ICASSP 2024摘要:在本文中,我们提出了一种用于潜在重叠声音的类增量学习的方法,用于解决一系列多标签音频分类任务。我们设计了一个增量学习器,它独立于旧类学习新类。为了保留有关旧类的知识,我们提出了一种基于余弦相似性的蒸馏损失,最大限度地减少后续学习者的特征表示的差异,并将其与基于Kullback-Leibler发散的蒸馏损失一起使用,最大限度地减少各自输出的差异。实验在具有50个声音类的数据集上进行,初始分类任务包含30个基本类和4个增量阶段,每个阶段5个类。在每个阶段之后,系统将使用到目前为止学习的整个类集进行多标签分类测试。所提出的方法在五个阶段中获得了40.9%的平均F1分数,范围从30个类的阶段0中的45.2%到50个类的阶段4中的36.3%。增量阶段的平均性能下降仅为初始F1分数45.2%的0.7个百分点。摘要:In this paper, we propose a method for class-incremental learning of potentially overlapping sounds for solving a sequence of multi-label audio classification tasks.

In this paper, we propose DI-AEC, pioneering a diffusion-based stochastic regeneration approach dedicated to AEC. Further, we propose FADI-AEC, fast score-based diffusion AEC framework to save computational demands, making it favorable for edge devices. It stands out by running the score model once per frame, achieving a significant surge in processing efficiency. Apart from that, we introduce a novel noise generation technique where far-end signals are utilized, incorporating both far-end and near-end signals to refine the score model's accuracy. We test our proposed method on the ICASSP2023 Microsoft deep echo cancellation challenge evaluation dataset, where our method outperforms some of the end-to-end methods and other diffusion based echo cancellation methods.【4】 Using perceptive subbands analysis to perform audio scenes cartography标题:利用感知子带分析进行音频场景制图链接:https://arxiv.org/abs/2401.04127作者:Laurent Millot,Gérard Pelé,Mohammed Elliq备注:None摘要:真实或模拟立体声录音的音频场景制图。该音频场景分析是连续进行的:感知10-子带分析,使用短时恒定场景假设和允许跟随移动源移动的通道间相关性计算每个子带的两个通道之间的相对延迟和增益的时间规律,计算其峰值给出固定源的发生率信息的全局和子带直方图。由2到4个固定源或一个固定源和一个移动源组成的音频场景已经成功测试。进一步的扩展和应用将被讨论。音频场景的音频插图,子带分析和实时立体声录音模拟的演示将被给出。论文6340在音频工程学会第118届会议上提出,巴塞罗那,2005年摘要:Audio scene cartography for real or simulated stereo recordings is presented.

Unlike prior work, MAGNeT is comprised of a single-stage, non-autoregressive transformer. During training, we predict spans of masked tokens obtained from a masking scheduler, while during inference we gradually construct the output sequence using several decoding steps. To further enhance the quality of the generated audio, we introduce a novel rescoring method in which, we leverage an external pre-trained model to rescore and rank predictions from MAGNeT, which will be then used for later decoding steps. Lastly, we explore a hybrid version of MAGNeT, in which we fuse between autoregressive and non-autoregressive models to generate the first few seconds in an autoregressive manner while the rest of the sequence is being decoded in parallel. We demonstrate the efficiency of MAGNeT for the task of text-to-music and text-to-audio generation and conduct an extensive empirical evaluation, considering both objective metrics and human studies. The proposed approach is comparable to the evaluated baselines, while being significantly faster (x7 faster than the autoregressive baseline). Through ablation studies and analysis, we shed light on the importance of each of the components comprising MAGNeT, together with pointing to the trade-offs between autoregressive and non-autoregressive modeling, considering latency, throughput, and generation quality.

To further improve the reconstruction ability and pitch accuracy to enhance the editability of user-provided sound, we propose HyperGANStrument, which introduces a pitch-invariant hypernetwork to modulate the weights of a pre-trained GANStrument generator, given a one-shot sound as input. The hypernetwork modulation provides feedback for the generator in the reconstruction of the input sound. In addition, we take advantage of an adversarial fine-tuning scheme for the hypernetwork to improve the reconstruction fidelity and generation diversity of the generator. Experimental results show that the proposed model not only enhances the generation capability of GANStrument but also significantly improves the editability of synthesized sounds.

However, existing methods for video-sound generation attempt to directly create sound from visual representations, which can be challenging due to the difficulty of aligning visual representations with audio representations. In this paper, we present SonicVisionLM, a novel framework aimed at generating a wide range of sound effects by leveraging vision language models. Instead of generating audio directly from video, we use the capabilities of powerful vision language models (VLMs). When provided with a silent video, our approach first identifies events within the video using a VLM to suggest possible sounds that match the video content. This shift in approach transforms the challenging task of aligning image and audio into more well-studied sub-problems of aligning image-to-text and text-to-audio through the popular diffusion models. To improve the quality of audio recommendations with LLMs, we have collected an extensive dataset that maps text descriptions to specific sound effects and developed temporally controlled audio adapters. Our approach surpasses current state-of-the-art methods for converting video to audio, resulting in enhanced synchronization with the visuals and improved alignment between audio and video components.

However, ASR-hypothesis-based retrieval can yield poor precision if the textual hypotheses are too phonetically dissimilar to the transcript truth. In this paper, we eliminate the hypothesis-audio mismatch problem by querying the correction database directly using embeddings derived from the utterance audio; the embeddings of the utterance audio and candidate corrections are produced by multimodal speech-text embedding networks trained to place the embedding of the audio of an utterance and the embedding of its corresponding textual transcript close together. After locating an appropriate correction candidate using nearest-neighbor search, we score the candidate with its speech-text embedding distance before adding the candidate to the original n-best list. We show a relative word error rate (WER) reduction of 6% on utterances whose transcripts appear in the candidate set, without increasing WER on general utterances.【10】 FunnyNet-W: Multimodal Learning of Funny Moments in Videos in the Wild标题:FunnyNet-W:野外视频中搞笑时刻的多模式学习链接:https://arxiv.org/abs/2401.04210作者:Zhi-Song Liu,Robin Courant,Vicky Kalogeiton备注:22 pages, 14 figures摘要:自动理解有趣的时刻(即,当观看喜剧时,让人发笑的时刻是具有挑战性的,因为它们涉及到各种特征,如肢体语言,对话和文化。在本文中,我们提出了FunnyNet-W,这是一种依赖于视觉,音频和文本数据的交叉和自我注意力来预测视频中有趣时刻的模型。与大多数依赖于字幕形式的地面实况数据的方法不同,在这项工作中,我们利用了视频中自然出现的模式:(a)视频帧,因为它们包含对于场景理解必不可少的视觉信息,(b)音频,因为它包含与有趣时刻相关联的高级线索,例如语调,音高和停顿,以及(c)用语音到文本模型自动提取的文本,因为它在由大型语言模型处理时可以提供丰富的信息。为了获取标签进行训练,我们提出了一种无监督的方法,可以发现和标记有趣的音频时刻。我们提供了五个数据集上的实验:情景喜剧TBBT,MHD,MUSTARD,朋友,和TED谈话UR-Funny。大量的实验和分析表明,FunnyNet-W成功地利用视觉,听觉和文本线索来识别有趣的时刻,而我们的研究结果揭示了FunnyNet-W的预测有趣的时刻在野外的能力。FunnyNet-W在所有数据集上使用多模态线索进行有趣时刻检测,使用和不使用地面真实信息。摘要:Automatically understanding funny moments (i.e., the moments that make people laugh) when watching comedy is challenging, as they relate to various features, such as body language, dialogues and culture. In this paper, we propose FunnyNet-W, a model that relies on cross- and self-attention for visual, audio and text data to predict funny moments in videos. Unlike most methods that rely on ground truth data in the form of subtitles, in this work we exploit modalities that come naturally with videos: (a) video frames as they contain visual information indispensable for scene understanding, (b) audio as it contains higher-level cues associated with funny moments, such as intonation, pitch and pauses and (c) text automatically extracted with a speech-to-text model as it can provide rich information when processed by a Large Language Model. To acquire labels for training, we propose an unsupervised approach that spots and labels funny audio moments. We provide experiments on five datasets: the sitcoms TBBT, MHD, MUStARD, Friends, and the TED talk UR-Funny. Extensive experiments and analysis show that FunnyNet-W successfully exploits visual, auditory and textual cues to identify funny moments, while our findings reveal FunnyNet-W's ability to predict funny moments in the wild. FunnyNet-W sets the new state of the art for funny moment detection with multimodal cues on all datasets with and without using ground truth information.【11】 Efficient Selective Audio Masked Multimodal Bottleneck Transformer for Audio-Video Classification标题:用于音视频分类的高效选择性音频掩蔽多模式瓶颈转换器链接:https://arxiv.org/abs/2401.04154作者:Wentao Zhu备注:Accepted by WACV 2024; well-formatted PDF is in this https URL arXiv admin note: text overlap with arXiv:2401.04023摘要:音频和视频是主流媒体平台中最常见的两种形式,例如,YouTube.为了有效地从多模态视频中学习,在这项工作中,我们提出了一种新的音频-视频识别方法,称为音频视频Transformer,AVT,利用视频Transformer的有效时空表示,以提高动作识别的准确性。对于多模态融合,在跨模态Transformer中简单地连接多模态标记需要大量的计算和存储资源,相反,我们通过音频-视频瓶颈Transformer来降低跨模态复杂度。为了提高多模态Transformer的学习效率,我们集成了自监督目标,即,音频-视频对比学习、音频-视频匹配和掩蔽音频和视频学习,到AVT训练中,其将不同的音频和视频表示映射到公共的多模态表示空间中。我们进一步提出了一个掩蔽的音频段损失,学习语义音频活动的AVT。在三个公共数据集和两个内部数据集上的大量实验和消融研究一致地证明了所提出的AVT的有效性。具体来说,AVT在Kinetics-Sounds上的表现比之前最先进的同类产品高出8%。AVT还通过利用音频信号,在VGGSound上超过了之前最先进的视频Transformers [25] 10%。与先前最先进的多模式方法之一MBT [32]相比,AVT在FLOP方面的效率提高了1.3%,并且在Epic-Kitchen-100上的准确性提高了3.8%。摘要:Audio and video are two most common modalities in the mainstream media platforms, e.g., YouTube. To learn from multimodal videos effectively, in this work, we propose a novel audio-video recognition approach termed audio video Transformer, AVT, leveraging the effective spatio-temporal representation by the video Transformer to improve action recognition accuracy. For multimodal fusion, simply concatenating multimodal tokens in a cross-modal Transformer requires large computational and memory resources, instead we reduce the cross-modality complexity through an audio-video bottleneck Transformer. To improve the learning efficiency of multimodal Transformer, we integrate self-supervised objectives, i.e., audio-video contrastive learning, audio-video matching, and masked audio and video learning, into AVT training, which maps diverse audio and video representations into a common multimodal representation space. We further propose a masked audio segment loss to learn semantic audio activities in AVT. Extensive experiments and ablation studies on three public datasets and two in-house datasets consistently demonstrate the effectiveness of the proposed AVT. Specifically, AVT outperforms its previous state-of-the-art counterparts on Kinetics-Sounds by 8%. AVT also surpasses one of the previous state-of-the-art video Transformers [25] by 10% on VGGSound by leveraging the audio signal. Compared to one of the previous state-of-the-art multimodal methods, MBT [32], AVT is 1.3% more efficient in terms of FLOPs and improves the accuracy by 3.8% on Epic-Kitchens-100.【12】 Cross-Speaker Encoding Network for Multi-Talker Speech Recognition标题:用于多说话人语音识别的跨话者编码网络链接:https://arxiv.org/abs/2401.04152作者:Jiawen Kang,Lingwei Meng,Mingyu Cui,Haohan Guo,Xixin Wu,Xunying Liu,Helen Meng备注:Accepted by ICASSP2024摘要:端到端的多说话人语音识别作为一种直接转录多个说话人重叠语音的有效方法已经引起了人们的极大兴趣。当前的方法通常采用1)具有分支编码器的单输入多输出(SIMO)模型,或者2)基于具有串行化输出训练(SOT)的基于注意力的编码器-解码器架构的单输入单输出(SISO)模型。在这项工作中,我们提出了一个跨扬声器编码(CSE)网络,以解决SIMO模型的限制,通过聚合跨扬声器表示。此外,CSE模型与SOT集成,以利用SIMO和SISO的优点,同时减轻它们的缺点。据我们所知,这项工作是一个早期的努力,集成SIMO和SISO多说话人语音识别。在两个说话人的LibrispeechMix数据集上的实验表明,CES模型比SIMO基线降低了8%的单词错误率(WER)。与SOT模型相比,CSE-SOT模型总体上将WER降低了10%,在高重叠语音上降低了16%。摘要:End-to-end multi-talker speech recognition has garnered great interest as an effective approach to directly transcribe overlapped speech from multiple speakers. Current methods typically adopt either 1) single-input multiple-output (SIMO) models with a branched encoder, or 2) single-input single-output (SISO) models based on attention-based encoder-decoder architecture with serialized output training (SOT). In this work, we propose a Cross-Speaker Encoding (CSE) network to address the limitations of SIMO models by aggregating cross-speaker representations. Furthermore, the CSE model is integrated with SOT to leverage both the advantages of SIMO and SISO while mitigating their drawbacks. To the best of our knowledge, this work represents an early effort to integrate SIMO and SISO for multi-talker speech recognition. Experiments on the two-speaker LibrispeechMix dataset show that the CES model reduces word error rate (WER) by 8% over the SIMO baseline. The CSE-SOT model reduces WER by 10% overall and by 16% on high-overlap speech compared to the SOT model.机器翻译由腾讯交互翻译提供,仅供参考
