I'm using VW Paul for my menu's which sounds great with the detection done by voice.pl, and I tried the same for voicebox as I was going to make an MP3 to demonstrate that honestly, I wasn't being delusional, I prommis. > The sapi_voice.vbs used by voice.pl is clever enough to detect > the engine, and set the optimal SAPI output format (for engines > we know). voiceBox, however, does not, but always uses the > format set near the top of voiceBox.wsf (const AUDIO_FORMAT). > This is something I did not change - it has always been like > this.

I will now go off and regenerate loads of my talk clips as I found a line that was commented out, so I'll try it. Previously selected was: ' Const AUDIO_FORMAT = 22 ' 16-bit 22 kHz Mono - AFAIK =) I'll try it with: Const AUDIO_FORMAT = 30 ' 16-bit 32 kHz Mono - AFAIK =) then anything else I happen to read about, look up, come up with, pull out of a hat, etc. Till it works.
