[mary-users] Increase speech rate of marytts

[Ingmar Steiner]

Dear Chrys

thanks for your message!

I'm afraid the Rate effect (i.e., the durScale parameter) seems to be 
broken in recent versions. There is an open bug report in our issue 
tracker, at https://github.com/marytts/marytts/issues/213

As suggested there, you could try to wrap your input text in MaryXML 
document, enclose it with a prosody element, and set its rate attribute. 
Then you need to change the input type of your request to RAWMARYXML 
instead of plain TEXT.

But since you are using a shell script, you could just as well call sox 
after synthesizing the audio, and use the speed effect like this:

> sox /tmp/marytts.wav /tmp/marytts_fast.wav speed 1.5

to increase the speech rate, before playing /tmp/marytts_fast.wav

Of course this will also raise the pitch, so to avoid a Mickey Mouse 
impression, you could play around with the TractScaler and/or F0Add 
effects to synthesize with a lower pitch, before you speed up the result.

Incidentally, you only need to specify the effects you want to use in 
the request. And you can use sox's play command to request the URL to 
synthesize, optionally process the result, and play in a single command:

> play -q 'http://localhost:59125/process?INPUT_TEXT=Hello+world&INPUT_TYPE=TEXT&OUTPUT_TYPE=AUDIO&AUDIO=WAVE_FILE&LOCALE=en_US&effect_TractScaler_selected=on&effect_TractScaler_parameters=amount:0.5&effect_f0Add_selected=on&effect_f0Add_parameters=f0Add:-100' speed 2.0

Hope this helps!

Best wishes,

-Ingmar
