torchaudio.prototype
====================
``torchaudio.prototype`` provides prototype features;
they are at an early stage for feedback and testing.
Their interfaces might be changed without prior notice.
Most modules of prototypes are excluded from release.
Please refer to `here <https://pytorch.org/audio>`_ for
more information on prototype features.
The modules under ``torchaudio.prototype`` must be
imported explicitly, e.g.
.. code-block:: python
import torchaudio.prototype.models
.. toctree::
prototype.functional
prototype.models
prototype.pipelines

The MuST-C model is configured with a vocabulary size of 500. Consequently, the MuST-C model's last linear layer in the joiner has an output dimension of 501 (500 + 1 to account for the blank symbol). In contrast to those of the datasets for the above two models, MuST-C's transcripts are cased and punctuated; we preserve the casing and punctuation when training the SentencePiece model.

# Conformer RNN-T ASR Example
This directory contains sample implementations of training and evaluation pipelines for a Conformer RNN-T ASR model.
## Setup
### Install PyTorch and TorchAudio nightly or from source
Because Conformer RNN-T is currently a prototype feature, you will need to either use the TorchAudio nightly build or build TorchAudio from source. Note also that GPU support is required for training.
To install the nightly, follow the directions at <https://pytorch.org/>.
To build TorchAudio from source, refer to the [contributing guidelines](https://github.com/pytorch/audio/blob/main/CONTRIBUTING.md).
### Install additional dependencies
```bash
pip install pytorch-lightning sentencepiece
```
## Usage
### Training
[`train.py`](./train.py) trains an Conformer RNN-T model (30.2M parameters, 121MB) on LibriSpeech using PyTorch Lightning. Note that the script expects users to have the following:
- Access to GPU nodes for training.
- Full LibriSpeech dataset.
- SentencePiece model to be used to encode targets; the model can be generated using [`train_spm.py`](./train_spm.py).
- File (--global_stats_path) that contains training set feature statistics; this file can be generated using [`global_stats.py`](../emformer_rnnt/global_stats.py).
Sample SLURM command:
```
srun --cpus-per-task=12 --gpus-per-node=8 -N 4 --ntasks-per-node=8 python train.py --exp_dir ./experiments --librispeech_path ./librispeech/ --global_stats_path ./global_stats.json --sp_model_path ./spm_unigram_1023.model --epochs 160
```
### Evaluation
[`eval.py`](./eval.py) evaluates a trained Conformer RNN-T model on LibriSpeech test-clean.
Sample SLURM command:
```
srun python eval.py --checkpoint_path ./experiments/checkpoints/epoch=159.ckpt --librispeech_path ./librispeech/ --sp_model_path ./spm_unigram_1023.model --use_cuda
```
The table below contains WER results for various splits.
| | WER |
|:-------------------:|-------------:|
| test-clean | 0.0310 |
| test-other | 0.0805 |
| dev-clean | 0.0314 |
| dev-other | 0.0827 |

the sum of batch sizes across all GPUs. Compute gradient from scaled loss.
- Sync and average gradients across all GPUs. The final gradient
