Hi Gang,
I'm working on a lumenvox app and am having "fun"
with the
Gotoif's on speech/DTMF recognition. If you're using DTMF to enter a
number
instead of speech to enter a numeric value, the engine will often return a
"confidence score" of 1000 instead of 1-999. Therefore this Gotoif
fails:
exten => s,n,GotoIf($["${SPEECH_SCORE(0)}" <=
"${THRESHOLD}"]?:tag)
${THRESHOLD} was set to 850.
If SPEECH_SCORE(0) <= 850 (1-850) fails
851-999 succeeds
1000 fails
My workaround was this:
exten => s,n,GotoIf($["${SPEECH_SCORE(0)}" = "1000"]?tag)
exten => s,n,GotoIf($["${SPEECH_SCORE(0)}" <=
"${THRESHOLD}"]?:tag)
Is there a better way than using to Gotoif's per evaluation?
Regards,
Danny Nicholas

I think the quotes cause the values to be compared as strings, not
numbers. The old shell programmer's trick (which allows for empty
strings):
exten => s,n,GotoIf($[0${SPEECH_SCORE(0)} <= 0${THRESHOLD}]?:tag)
ought to cause a numeric comparison.
