GPST PyTorch Implementation

This is a PyTorch implementation of the paper Generative Pre-Trained Speech Language Model with Efficient Hierarchical Transformer.

Overview

Demo page: https://youngsheen.github.io/GPST/demo

The overview of GPST as following picture shows. The overview of GPST

Installation

  1. Download the code
git clone https://github.com/youngsheen/GPST.git
cd GPST

  1. Install fairseq and encodec via pip. Install seamless_communication and fairseq2.

  2. [Optional] Install flash-attn for faster attention computation.

Preparation

Dataset

Download the LibriSpeech or LibriLight dataset and place it in your directory at $PATH_TO_YOUR_WORKSPACE/datasets. We use xlsr2_1b_v2 from SeamlessM4T to extract semantic tokens and Encodec to extract acoustic tokens. You can set the bandwidth to 6kbps or 12 kbps to control the quality of speech resynthesis. We suggest using bandwidth=12 since the former half of its acoustic tokens are the same as 6kbps. The scripts will generate a manifest containing the path of all files, two lmdb folders containing semantic tokens and acoustic tokens separately.
