Description

Automatic speech recognition (ASR) is a core technology to create convenient human-computer interfaces. But building ASR systems with competitive word error rate (WER) traditionally required specialized expertise, large labeled datasets, and complex approaches.

Jason Li and Vitaly Lavrukhin dive into how end-to-end models simplified speech recognition and present Jasper, an end-to-end convolutional neural acoustic model, which yields state-of-the-art WER on LibriSpeech, an open dataset for speech recognition. They explore its implementation in the TensorFlow-based OpenSen2Seq toolkit and how to use it to solve large vocabulary speech recognition and speech command recognition problems. OpenSeq2Seq is an open source deep learning toolkit. They provide pretrained models for out-of-the-box experimentation.

Prerequisite knowledge

  • A basic understanding of deep learning and convolutional neural networks

What you'll learn
