Thanks for feedback.
1. The talking rate currently defaults to the default rate of the IBMTTS
synth. You can adjust speed in three ways. a) Get your application to
increase speed by sending SSIP SET RATE command. b) Uncomment and adjust
DefaultRate line in speechd.conf file. c) Uncomment the
IbmttsVoiceParameters lines in the ibmtts.conf file and increase the numbers
in the Speed column.
2. With the DefaultVolume parameter in speechd.conf defaulting to 100, the
ibmtts module is already setting the volume to maximum, according to the eci
technical docs. I don't know if it can go louder. Will investigate.
3. Will investigate grave accent crashing. Are there other inputs you can
give us to investigate? What voice (both Speech Dispatcher and IBM TTS) are
you using when it crashes?
4. Inflection is up to the synth. You might be able to increase inflection
by changing Pitch Flc in the aforementioned IbmttsVoiceParameters lines.
