A2W Segmental Model (SLT'2021)

This repo contains the code for A2W segmental model Whole-Word Segmental Speech Recognition with Acoustic Word Embeddings

Requirements

• Kaldi
• g++ 5.5.0
• CUDA 10.0
• Pytorch 1.4.0
• kaldi-io

Usage:

1. Use Kaldi for data preparation: setting up data dir, extracting fbank feature, computing and applying CMVN.

2. Extract word list and map words into ids. This can be done via src/preproc/prep_seg_word.py.

3. Edit paths for feature and text data in the configuration file (in conf/). An example of data and configuration file can be found in data/ and src/conf/.

4. Training and evaluation

cd src
./run.sh

! Note before running ./run.sh, make sure following paths are correctly set including KALDI_ROOT in path.sh, CC,CXX,PATH,LD_LIBRARY_PATH in run.sh

ToDo:

• Code release for segmental model
• Code release for AWE/AGWE pre-training
