step1：安装pocketsphinx阶段
问题
Error opening audio device default for capture: No such file or directory
FATAL_ERROR: "continuous.c", line 242: Failed top open audio device
搜了下网络，大概含义是找不到话筒。网络建议修改命令如下：
pocketsphinx_continuous -adcdev hw:AudioPCI
依然有问题如下：
Error opening audio device hw:AudioPCI for capture: No such device
FATAL_ERROR: "continuous.c", line 242: Failed top open audio device
【sphinx】训练自己的模型
使用如下命令时候
./bw -hmmdir tdt_sc_8k -moddeffn tdt_sc_8k/mdef.txt -ts2cbfn .semi. -feat 1s_c_d_dd -svspec 0-12/13-25/26-38 -cmn current -agc none -dictfn arctic20.dic -ctlfn arctic20.fileids -lsnfn arctic20.transcription -accumdir .
发生错误如下：
ERROR: "backward.c", line 430: Failed to align audio to trancript: final state of the search is not reached
12个句子。每个都报这个错误。查了下说是transcript和音频对不上。应该是录音时候，前后有杂音，导致他们对不上。
