目录：

1.安装portaudio

2.编译onlinebin

3.创建脚本测试

 

1.安装Portaudio：

$cd ~/kaldi-trunk/tools/

$./install_portaudio.sh 这里需要修改一处配置，不然后面可能会出现这些错误

<span style="font-size:18px;">kaldi portaudio/src/hostapi/jack/pa_jack.c:1734: undefined reference to `jack_get_sample_rate</span>

2.编译onlinebin

 

$cd ~/kaldi-trunk/src/onlinebin/

$make

 

3.创建脚本测试：

 

$cd ~/kaldi-trunk/egs/timit/s5/exp/tri1/

$vim test_online_decode.sh

添加如下一段：

/kaldi-trunk/src/onlinebin/online-wav-gmm-decode-faster --rt-min=0.3 --rt-max=0.5 --max-active=4000 --beam=12.0 --acoustic-scale=0.0769 scp:../../data/train/split10/1/wav.scp final.mdl graph/HCLG.fst graph/words.txt '1:2:3:4:5' ark,t:trans.txt ark,t:ali.txt

$sudo ./test_online_decode.sh 运行  

如果出现错误可能是由于权限不足导致，如下的错误提示：
