# 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 ](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md ).
You can choose one way from easy, meduim and hard to install paddlespeech.
### 2. Prepare Input File
The input of this 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:
```bash
wget -c https://paddlespeech.bj.bcebos.com/vector/audio/85236145389.wav
```
### 3. Usage
- Command Line(Recommended)
```bash
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
```
Usage:
```bash
paddlespeech vector --help
```
Arguments:
- `input` (required): Audio file to recognize.
- `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.
