庆科VBS7100 语音识别

tobot

我在使用庆科VBS7100做象棋输入的时候，使用了
AT+ASRADD=yi,49
AT+ASRADD=er,50
AT+ASRADD=san,51
AT+ASRADD=si,52
AT+ASRADD=wu,53
AT+ASRADD=liu,54
AT+ASRADD=qi,55
AT+ASRADD=ba,56
AT+ASRADD=jiu,57


AT+ASRADD=ju,114
AT+ASRADD=ma,113
AT+ASRADD=pao,115
AT+ASRADD=xiang,112
AT+ASRADD=shi,111
AT+ASRADD=bing,116

AT+ASRADD=jin,97
AT+ASRADD=ping,98
AT+ASRADD=tui,99

AT+ASRADD=qian,120
AT+ASRADD=hou,121
AT+ASRADD=zhong,122

对语音的识别率非常低，往往只能识别出首个字，比如“炮二平5”只能识别出“炮”，或者根本就直接提示+ASREVENT:255，不知道有没有好的解决办法？
