Tensorflowasr

Release Notes

- Fix tflite conversion and interpretation on Transducer's Greedy Decoding, the reason is somehow tflite drops support for `tf.cond` so we have to use `tf.where` instead. Tested on `tensorflow==2.3.1` and `tf-nightly`
- Small update on `BaseTrainer` class: infinity evaluation after training is done, refactor some utility functions
- Update `SentencePieceFeaturizer`

Release Notes

- Add downloading script for Multilingual LibriSpeech dataset
- Add `SentencePieceFeaturizer`
- Remove `tf.string` from Transducer Beam Search for GPU support
- Add RNNT implementation in pure TF (Ref: [https://github.com/iamjanvijay/rnnt](https://github.com/iamjanvijay/rnnt))
- Add option for tfrecords shards and buffer size

Release Notes

- Update dependencies
- Fix Transducer RNN name

Release Notes

- Add unittests
- Fixed CTC `recognize_tflite` and `recognize_tflite_beam`
- Add `joint_activation` to Transducer

Release Notes

- Supported *naive* token level timestamp
- Updated `iextract` and `indices2upoint` with ignoring blanks

Release Notes

- Update demo examples and dependencies
