(Prototype) CTC Beam Search Decoder
In recent releases, TorchAudio has added support for ASR models fine-tuned on CTC loss. The addition of an inference time CTC beam search decoder enables running end-to-end ASR evaluation using TorchAudio utils.
The CTC decoder in TorchAudio supports customizable beam search decoding with lexicon constraint. It also has optional KenLM language model support.
For more details, please check out the API tutorial and documentation. This prototype feature is available through nightly builds.
(Prototype) Streaming API
TorchAudio started as simple audio I/O APIs that supplement PyTorch. With the recent addition of ASR models and training recipes, the project has received requests to support high-level application development.
