Need to slow down the confirmation number

[msh]

Hi,

The plum dev voice system is reading a confirmation number too fast for some of our users. Is there a way to slow down just that particular part?

thanks,

Hi,

Yes, there is a very simple solution to change the rate of TTS.

You can use the <prosody> tag with the 'rate' attribute to change the rate in which your TTS is played.

Here is an example of slowing down the rate of TTS using this tag.

Code: Select all

<form>
  <block>
    <prompt>
      <prosody rate="-20%">This is a slow prompt.</prosody>
      <prosody rate="-50%">This is a slower prompt.</prosody>
    </prompt>
  </block>
</form>

Note that using +/- percentages as the rate will work for all TTS engines (AT&T, Cepstral, & RealSpeak). However, with the AT&T engine you can specify an integer value for the rate, 150 being the default rate of speech.

Please feel free to let us know if you have any additional questions.
