Tts Cepstral

[Guest u4910]

I like the sound of the PC version of the TTS voice versus the 8k version for telephony. Will the PC version work fine for Voice Guide?

They will both sound fairly similar when played over the phone line as the phone lines have a bandwidth of about 3-4kHz anyway. Often the bandwidth is less - especially on mobile connections.

 

The 8kHz version should be designed to sound better in lower bandwidth mode, so we recommend selecting the 8kHz TTS engines for telephony applications.

How do I specify VG to use the Cepstral voice? How do I know the exact name (for William for example).

VoiceGuide lists all TTS voices installed on the system in the ktTts log file. Entries listing the installed TTS voices look like this:

 

104228.247 2744 il GetId call

104228.247 2744 il wtoc + _wcsicmp calls

104228.247 2744 il voice 0 is: [LH Michael], ID=[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\LHMICHAEL]

104228.247 2744 il SpGetDescription call

104228.277 2744 il GetId call

104228.277 2744 il wtoc + _wcsicmp calls

104228.293 2744 il voice 1 is: [ATT DTNV 1.4 Crystal16], ID=[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\ATT-DT-14-Crystal16]

104228.293 2744 il SpGetDescription call

104228.293 2744 il GetId call

 

The above extract shows two voices: "LH Michael" and "ATT DTNV 1.4 Crystal16"

 

To use the LH Michael voice the [sAPI]section of VG.INI should look like this:

 

[sAPI]

TTSEngine=LH Michael

 

To use the AT&T Crystal voice the [sAPI]section of VG.INI should look like this:

 

[sAPI]

TTSEngine=ATT DTNV 1.4 Crystal16

 

So you just need to see how the TTS engines installed on your system identify themselves as (by looking in ktTts) and then use these names in the VG.INI file.

That worked thanks!
