# Speech Transformer: End-to-End ASR with Transformer A PyTorch implementation of Speech Transformer [1], an end-to-end automatic speech recognition with [Transformer](https://arxiv.org/abs/1706.03762) network, which directly converts acoustic features to character sequence using a single nueral network. ## Install - Python3 (recommend Anaconda) - PyTorch 0.4.1+ - [Kaldi](https://github.com/kaldi-asr/kaldi) (just for feature extraction) - `pip install -r requirements.txt` - `cd tools; make KALDI=/path/to/kaldi` - If you want to run `egs/aishell/run.sh`, download [aishell](http://www.openslr.org/33/) dataset for free. ## Usage ### Quick start ```bash $ cd egs/aishell # Modify aishell data path to your path in the begining of run.sh $ bash run.sh ``` That's all! You can change parameter by `$ bash run.sh --parameter_name parameter_value`, egs, `$ bash run.sh --stage 3`. See parameter name in `egs/aishell/run.sh` before `. utils/parse_options.sh`. ### Workflow Workflow of `egs/aishell/run.sh`: - Stage 0: Data Preparation - Stage 1: Feature Generation - Stage 2: Dictionary and Json Data Preparation - Stage 3: Network Training - Stage 4: Decoding ### More detail `egs/aishell/run.sh` provide example usage. ```bash # Set PATH and PYTHONPATH $ cd egs/aishell/; . ./path.sh # Train $ train.py -h # Decode $ recognize.py -h ``` #### How to visualize loss? If you want to visualize your loss, you can use [visdom](https://github.com/facebookresearch/visdom) to do that: 1. Open a new terminal in your remote server (recommend tmux) and run `$ visdom`. 2. Open a new terminal and run `$ bash run.sh --visdom 1 --visdom_id "<any-string>"` or `$ train.py ... --visdom 1 --vidsdom_id "<any-string>"`. 3. Open your browser and type `<your-remote-server-ip>:8097`, egs, `127.0.0.1:8097`. 4. In visdom website, chose `<any-string>` in `Environment` to see your loss.  #### How to resume training? ```bash $ bash run.sh --continue_from <model-path> ``` #### How to solve out of memory? When happened in training, try to reduce `batch_size`. `$ bash run.sh --batch_size <lower-value>`. ## Results | Model | CER | Config | | :---: | :-: | :----: | | LSTMP | 9.85| 4x(1024-512). See [kaldi-ktnet1](https://github.com/kaituoxu/kaldi-ktnet1/blob/ktnet1/egs/aishell/s5/local/nnet1/run_4lstm.sh)| | Listen, Attend and Spell | 13.2 | See [Listen-Attend-Spell](https://github.com/kaituoxu/Listen-Attend-Spell)'s egs/aishell/run.sh | | SpeechTransformer | 12.8 | See egs/aishell/run.sh | ## Reference - [1] Yuanyuan Zhao, Jie Li, Xiaorui Wang, and Yan Li.
