TensorFlowASR v0.7.0

Release Notes

• Implement Slice Dataset that yield data in keras format (x, y)
• Implement TFRecord Dataset that yield data in keras format (x, y)
• Add new RnntLoss subclass of tf.keras.losses.Loss to use in compile function of tf.keras.Model
• Add Transducer with custom train_step and test_step that uses RnntLoss
• Add new CtcLoss subclass of tf.keras.losses.Loss to use in compile function of tf.keras.Model
• Add CtcModel with custom train_step and test_step that uses CtcLoss

TensorFlowASR v0.6.4

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

TensorFlowASR v0.6.3

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)
• Add option for tfrecords shards and buffer size

TensorFlowASR v0.6.2

Release Notes

• Update dependencies
• Fix Transducer RNN name

TensorFlowASR v0.6.1

Release Notes

• Add unittests
• Fixed CTC recognize_tflite and recognize_tflite_beam
• Add joint_activation to Transducer

TensorFlowASR v0.6.0

Release Notes

• Supported naive token level timestamp
• Updated iextract and indices2upoint with ignoring blanks

TensorFlowASR v0.5.5

Release Notes

• Update demo examples and dependencies
• Change double underscore function name to single underscore

TensorFlowASR v0.5.4

Release Notes

• Fixed minor bugs in printing summary, get number of batches for tfrecords
• Update docs

TensorFlowASR v0.5.3

Release Notes

• Fixed tfrecords dataset that doesn't require transcripts.tsv files
• Remove summary for encoder in Transducer.summary to deal with the None encoder

TensorFlowASR v0.5.2

Release Notes

• Fix TFLite Conversion for Transducer Greedy
