Speech Verification

Introduction

Speaker Verification, refers to the problem of getting a speaker embedding from an audio.

This demo is an implementation to extract speaker embedding from a specific audio file. It can be done by a single command or a few lines in python using PaddleSpeech.

Usage

1. Installation

see installation.

You can choose one way from easy, meduim and hard to install paddlespeech.

2. Prepare Input File

The input of this cli demo should be a WAV file(.wav), and the sample rate must be the same as the model.

Here are sample files for this demo that can be downloaded:

wget -c https://paddlespeech.bj.bcebos.com/vector/audio/85236145389.wav
wget -c https://paddlespeech.bj.bcebos.com/vector/audio/123456789.wav

3. Usage

  • Command Line(Recommended)

    paddlespeech vector --task spk --input 85236145389.wav

echo -e "demo1 85236145389.wav" > vec.job
paddlespeech vector --task spk --input vec.job

echo -e "demo2 85236145389.wav \n demo3 85236145389.wav" | paddlespeech vector --task spk

paddlespeech vector --task score --input "./85236145389.wav ./123456789.wav"

echo -e "demo4 85236145389.wav 85236145389.wav \n demo5 85236145389.wav 123456789.wav" > vec.job
paddlespeech vector --task score --input vec.job

    Usage:

    paddlespeech vector --help

    Arguments:

    • input(required): Audio file to recognize.
    • task (required): Specify vector task. Default spk。
    • model: Model type of vector task. Default: ecapatdnn_voxceleb12.
    • sample_rate: Sample rate of the model. Default: 16000.
    • config: Config of vector task. Use pretrained model when it is None. Default: None.
    • ckpt_path: Model checkpoint. Use pretrained model when it is None. Default: None.
    • device: Choose device to execute model inference. Default: default device of paddlepaddle in current environment.
