@reuben reuben released this Nov 4, 2020 · 58 commits to master since this release

General

This is the 0.9.1 release of Deep Speech, an open speech-to-text engine. In accord with semantic versioning, this version is not completely backwards compatible with earlier versions. However, models exported for 0.7.X and 0.8.X should work with this release. This is a bugfix release and retains compatibility with the 0.9.0 models. All model files included here are identical to the ones in the 0.9.0 release. As with previous releases, this release includes the source code:

v0.9.1.tar.gz

Under the MPL-2.0 license. And the acoustic models:

deepspeech-0.9.1-models.pbmm
deepspeech-0.9.1-models.tflite

In addition we're releasing experimental Mandarin Chinese acoustic models trained on an internal corpus composed of 2000h of read speech:

deepspeech-0.9.1-models-zh-CN.pbmm
deepspeech-0.9.1-models-zh-CN.tflite

all under the MPL-2.0 license.

The model files with the ".pbmm" extension are memory mapped and thus memory efficient and fast to load. The model files with the ".tflite" extension are converted to use TensorFlow Lite, has post-training quantization enabled, and are more suitable for resource constrained environments.

The acoustic models were trained on American English with synthetic noise augmentation and the .pbmm model achieves an 7.06% word error rate on the LibriSpeech clean test corpus.

Note that the model currently performs best in low-noise environments with clear recordings and has a bias towards US male accents. This does not mean the model cannot be used outside of these conditions, but that accuracy may be lower. Some users may need to train the model further to meet their intended use-case.

In addition we release the scorer:

deepspeech-0.9.1-models.scorer

which takes the place of the language model and trie in older releases and which is also under the MPL-2.0 license.

There is also a corresponding scorer for the Mandarin Chinese model:

deepspeech-0.9.1-models-zh-CN.scorer

We also include example audio files:

audio-0.9.1.tar.gz

which can be used to test the engine, and checkpoint files for both the English and Mandarin models:

deepspeech-0.9.1-checkpoint.tar.gz
deepspeech-0.9.1-checkpoint-zh-CN.tar.gz

which are under the MPL-2.0 license and can be used as the basis for further fine-tuning.

Notable changes from the previous release

  • Fixed problem with documentation build on ReadTheDocs.org (#3399)

Training Regimen + Hyperparameters for fine-tuning

The hyperparameters used to train the model are useful for fine tuning. Thus, we document them here along with the training regimen, hardware used (a server with 8 Quadro RTX 6000 GPUs each with 24GB of VRAM), and our use of cuDNN RNN.

In contrast to some previous releases, training for this release occurred as a fine tuning of the previous 0.8.2 checkpoint, with data augmentation options enabled. The following hyperparameters were used for the fine tuning. See the 0.8.2 release notes for the hyperparameters used for the base model.

  • train_files Fisher, LibriSpeech, Switchboard, Common Voice English, and approximately 1700 hours of transcribed WAMU (NPR) radio shows explicitly licensed to use as training corpora.
  • dev_files LibriSpeech clean dev corpus.
  • test_files LibriSpeech clean test corpus
  • train_batch_size 128
  • dev_batch_size 128
  • test_batch_size 128
  • n_hidden 2048
  • learning_rate 0.0001
  • dropout_rate 0.40
  • epochs 200
  • augment pitch[pitch=1~0.1]
  • augment tempo[factor=1~0.1]
  • augment overlay[p=0.9,source=${noise},layers=1,snr=12~4] (where ${noise} is a dataset of Freesound.org background noise recordings)
  • augment overlay[p=0.1,source=${voices},layers=10~2,snr=12~4] (where ${voices} is a dataset of audiobook snippets extracted from Librivox)
  • augment resample[p=0.2,rate=12000~4000]
  • augment codec[p=0.2,bitrate=32000~16000]
  • augment reverb[p=0.2,decay=0.7~0.15,delay=10~8]
  • augment volume[p=0.2,dbfs=-10~10]
  • cache_for_epochs 10

The weights with the best validation loss were selected at the end of 200 epochs using --noearly_stop.

The optimal lm_alpha and lm_beta values with respect to the LibriSpeech clean dev corpus remain unchanged from the previous release:

  • lm_alpha 0.931289039105002
  • lm_beta 1.1834137581510284

For the Mandarin Chinese model, the following values are recommended:

  • lm_alpha 0.6940122363709647
  • lm_beta 4.777924224113021

Bindings

This release also includes a Python based command line tool deepspeech, installed through

pip install deepspeech

Alternatively, quicker inference can be performed using a supported NVIDIA GPU on Linux. (See below to find which GPU's are supported.) This is done by instead installing the GPU specific package:

pip install deepspeech-gpu

On Linux, macOS and Windows, the DeepSpeech package does not use TFLite by default. A TFLite version of the package on those platforms is available as:

pip install deepspeech-tflite

Also, it exposes bindings for the following languages

  • Python (Versions 3.5, 3.6, 3.7 and 3.8) installed via

General

This is the 0.8.2 release of Deep Speech, an open speech-to-text engine. In accord with semantic versioning, this version is not completely backwards compatible with earlier versions. However, models exported for 0.7.X should work with this release. As with previous releases, this release includes the source code:

v0.8.2.tar.gz

and the acoustic models:

deepspeech-0.8.2-models.pbmm
deepspeech-0.8.2-models.tflite

The model with the ".pbmm" extension is memory mapped and thus memory efficient and fast to load. The model with the ".tflite" extension is converted to use TFLite, has post-training quantization enabled, and is more suitable for resource constrained environments.

The acoustic models were trained on American English and the pbmm model achieves an 5.97% word error rate on the LibriSpeech clean test corpus.

Note that the model currently performs best in low-noise environments with clear recordings and has a bias towards US male accents. This does not mean the model cannot be used outside of these conditions, but that accuracy may be lower. Some users may need to train the model further to meet their intended use-case.

In addition we release the scorer:

which can be used to test the engine, and checkpoint files:

which are under the MPL-2.0 license and can be used as the basis for further fine-tuning.

Notable changes from the previous release

  • Fixed incorrect minimum OS version in macOS binaries (#3259)
  • Fixed bug in metadata output for Python package client (#3264)
  • Added ElectronJS v9.2 support (#3266)

Training Regimen + Hyperparameters for fine-tuning

The hyperparameters used to train the model are useful for fine tuning. Thus, we document them here along with the training regimen, hardware used (a server with 8 Quadro RTX 6000 GPUs each with 24GB of VRAM), and our use of cuDNN RNN.

In contrast to some previous releases, training for this release occurred in several phases each phase with a lower learning rate than the phase before it.

The initial phase used the hyperparameters:

  • train_files Fisher, LibriSpeech, Switchboard, Common Voice English, and approximately 1700 hours of transcribed WAMU (NPR) radio shows explicitly licensed to use as training corpora.
  • dev_files LibriSpeech clean dev corpus.
  • test_files LibriSpeech clean test corpus
  • train_batch_size 128
  • dev_batch_size 128
  • test_batch_size 128
  • n_hidden 2048
  • learning_rate 0.0001
  • dropout_rate 0.40
  • epochs 125

The weights with the best validation loss were selected at the end of 125 epochs using --noearly_stop.

The second phase was started using the weights with the best validation loss from the previous phase. This second phase used the same hyperparameters as the first but with the following changes:

  • learning_rate 0.00001
  • epochs 100

The weights with the best validation loss were selected at the end of 100 epochs using --noearly_stop.

Like the second, the third phase was started using the weights with the best validation loss from the previous phase. This third phase used the same hyperparameters as the second but with the following changes:

  • learning_rate 0.000005

The weights with the best validation loss were selected at the end of 100 epochs using --noearly_stop. The model selected under this process was trained for a sum total of 732522 steps over all phases.

Subsequent to this the lm_optimizer.py was used with the following parameters:

  • lm_alpha_max 5
  • lm_beta_max 5
  • n_trials 2400
  • test_files LibriSpeech clean dev corpus.

to determine the optimal lm_alpha and lm_beta with respect to the LibriSpeech clean dev corpus. This resulted in:

  • lm_alpha 0.931289039105002
  • lm_beta 1.1834137581510284
