HTK训练遇到的问题
HLed
F:\train2\pre_data>HLEd.exe -l * -d cmudict_add2_add3.dict -i third_phone.mlf w2
mono.led third_word.mlf
ERROR [+5013] ReadString: String too long
FATAL ERROR - Terminating program HLEd.exe
solution:
Make changes to the pronunciation dictionary:
Replace all multiple spaces with single space;
Replace all tabs with single space;
Put a '' before every double quote ("); %"
Put a '' before any dictionary entry beginning with single quote (')
检查了生成的phone文件，查找出错位置，发现third_word.mlf下一条lab中出现了's符号。原因是原文本中teacher’s中间出现了空格

ERROR [+6550] LoadHTKLabels: Junk at end of HTK transcription
FATAL ERROR - Terminating program HLEd.exe
Add -T 1 to the command line. Where it stops, look in the .mlf file for that transcription. There may be a blank line or something kooky in it. This will help you find a lot of the errors that HLEd comes up with.
mlf中有空行。

FATAL ERROR - Terminating program F:\train2\htktools\HResults.exe
solution：Add -T 1 to the command line. Where it stops, look in the .mlf file for that transcription. There may be a blank line or something kooky in it. This will help you find a lot of the errors that HLEd comes up with.
实际是识别文件中出现了为识别的空行，打开rec.mlf，找到空行删除即可。
"F:/train2/seconddata/feature/speech1003-0009.rec"
.
2、F:\train2>F:\train2\htktools\HResults.exe -f -t -I F:\train2\seconddata\second_word.mlf F:\train2\data\lists\Iter1\tiedlist F:\train2\out_rec.mlf > second_all.result
ERROR [+6570] GetLabelList: n[1] > numLists[0]
FATAL ERROR - Terminating program F:\train2\htktools\HResults.exe
solution：Run the command again with -f to show full results. Look in the reference mlf file at the utterance _after_ the last one listed before the error shows up. It's empty. Put something there or remove it (must be removed from reference).
实际是lab文件为空行，删除即可。
"*/speech04-0057.lab"

扩展为3音素后，重估

经检查，train.scp 和.lab以及 .mlf都没问题，发现lab文件夹里的cri.mlf有问题。
