I have a cepstral Allison voice for 16khz. I am using javasrcipt session.speak.
The audio output is not nearly as good as what comes out directly from swift.
I am guessing that speak is down sampling to 8khz. Is this true?
Is there a way to get speak to not do this?

Thanks

is the call 8khz? If you call with a 16khz codec like g722 it should choose 16k

Ok,
That explains your question then.
Since g711 is an 8khz codec, the system will downsample the audio to match and you will lose some of the clarity.
