声纹识别是一项用计算机程序自动提取说话人特征的技术。
这个 demo 是从一个给定音频文件中提取说话人特征，它可以通过使用 PaddleSpeech 的单个命令或 python 中的几行代码来实现。
请看安装文档。
你可以从easy medium，hard 三种方式中选择一种方式安装。
声纹cli demo 的输入应该是一个 WAV 文件（.wav），并且采样率必须与模型的采样率相同。
可以下载此 demo 的示例音频：
# 该音频的内容是数字串 85236145389
wget -c https://paddlespeech.bj.bcebos.com/vector/audio/85236145389.wav
wget -c https://paddlespeech.bj.bcebos.com/vector/audio/123456789.wav-
命令行 (推荐使用)
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
使用方法：
paddlespeech vector --help
参数：
input(必须输入)：用于识别的音频文件。task(必须输入): 用于指定vector处理的具体任务，默认是spk。model：声纹任务的模型，默认值：ecapatdnn_voxceleb12。sample_rate：音频采样率，默认值：16000。config：声纹任务的参数文件，若不设置则使用预训练模型中的默认配置，默认值：None。ckpt_path：模型参数文件，若不设置则下载预训练模型使用，默认值：None。device：执行预测的设备，默认值：当前系统下 paddlepaddle 的默认 device。
