详细介绍
We explore the application of end-to-end stateless temporal modeling to
small-footprint keyword spotting as opposed to recurrent networks that model
long-term temporal dependencies using internal states. We propose a model
inspired by the recent success of dilated convolutions in sequence modeling
applications, allowing to train deeper architectures in resource-constrained
configurations. Gated activations and residual connections are also added,
following a similar configuration to WaveNet. In addition, we apply a custom
target labeling that back-propagates loss from specific frames of interest,
therefore yielding higher accuracy and only requiring to detect the end of the
keyword. Our experimental results show that our model outperforms a max-pooling
loss trained recurrent neural network using LSTM cells, with a significant
decrease in false rejection rate. The underlying dataset - "Hey Snips"
utterances recorded by over 2.2K different speakers - has been made publicly
available to establish an open reference for wake-word detection.
