([简体中文](./README_cn.md)|English) # 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 asr --help ``` Arguments: - `input`(required): Audio file to recognize. - `model`: Model type of asr task. Default: `conformer_wenetspeech`. - `sample_rate`: Sample rate of the model. Default: `16000`. - `config`: Config of asr 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.
