Not sure what could cause this, if the input is being treat as a
very long single sentence (as a single utterances) the pitch
can drop to a low level and sit there at a monotone. Though I've
not heard it slowing down.
Using the festival_client standalone program you can ensure you
don't get things a single utterance is you use --async and --ttw
but you'll get (potentiall) multiple waveform files sent back as they
are synthesized.
festival_client --async --ttw --aucommand 'na_play $FILE' fred.txt
If this doesn't help can you point me at the some text and an example
waveform that is being generate and I might be able to trace this
further.
