下面是公开课的回顾：
The previous decade saw remarkable development in automatic speech recognition technologies. While there are a lot of technical articles explaining the improvements from the model point of view, the impact of datasets and benchmarks to speech recognition development is not well studied. In this talk, we first investigate the contribution of datasets and benchmarks to speech recognition development. We then introduce a large scale English speech recognition dataset named GigaSpeech. We will demonstrate the data creation pipeline, as well as initial benchmarks on this dataset. Finally, we close this talk by outlining our on-going work for speech recognition benchmarks.
至此，本期公开课圆满结束。语音之家将持续为大家带来干货满满的技术分享，敬请关注！
