wav file not generated

[naveenpalani]

I have been using Cepstral Callie-8kHz voice (lincesed) on my asterisk box. Use the swift engine to convert the text to speech wav file. But right now the wav file is not generated for the application to play it. Can there be any thing that iam missing and its because of this the wav file is not generated.

I use

swift -o /tmp/$agi_uniqueid.wav -p audio/channels=1, audio/sampling-rate=8000 "$text"

to generate the wave file.
