MSA-ASR

Multilingual Speaker-Attributed Automatic Speech Recognition

Demo

Introduction

This repository provides an implementation of a Speaker-Attributed Automatic Speech Recognition model. The model performs both multilingual speech recognition and speaker embedding extraction, enabling speaker differentiation.

Model architecture

Setup

git clone git@github.com:nguyenvulebinh/MSA-ASR.git
cd MSA-ASR
conda create -n MSA-ASR python=3.10
conda activate MSA-ASR
pip install -r requirements.txt

Test script:

python infer.py

Training Dataset

From ASR to SA-ASR dataset:

Segment ASR data into single-speaker turns.
Match turns into group which may come from the same speaker by using speaker embedding cosine similarity.
Pick a few groups, each group a few turns.
Concatenate turns in random order.

In total:

15.5M turns
14k audio hours
English only

Dataset is openly available in HF Dataset
