A demo of chinese asr

Overview

chinese_asr_demo

一个端到端的中文语音识别模型训练、测试框架 具备数据预处理、模型训练、解码、计算wer等等功能

训练数据

训练数据采用thchs_30,下载地址:http://www.openslr.org/18/ 下载后将data_thchs30解压到data文件中

使用模型

bi-lstm + ctc 可直接将语音转换为中文

生成训练文件格式

预处理

1、提取80维fbank特征

2、标准化:计算特征的均值和方差进行标准化,加快模型收敛速度,因为计算标准化的速度较慢,已将参数放到data_file/thchs_30/stand_nor.txt文件中,可直接调用

模型下载

bi_lstm_150_nl, 测试集wer为29.278%

计划

1、加入CNN降维度

2、更新tranformer,conformer模型

3、更新其他数据集的训练方法

4、更新其他解码方法
