I am using text to speech on Captivate 4. Essentially, I love the text-to-speech feature; however, sometimes the voice is just too fast. I do not want to add pointless punctuation because I use the same text for the Closed Captioning. Does anyone know how to slow down the voice (Paul) so people actually can follow what he is saying.
Thanks !!
Adobe implemented VTML in Captivate 4, which is a mark up language for Text to Speech.
It looks something like this (The color added for emphasis):
Lorem ipsum dolor sit amet \pause, consectetur \speed=30 adipisicing elit \speed=50 \pause, sed do eiusmod tempor \speed=30 incididunt \pitch=20 ut
The \pause, creates a half second pause and and a \pause. creates a full second pause
The \speed= changes the speed for all the text that comes after the tag in that segment. In this case I took it down to 30 and then brought it back up to 50 before the pause and then down again at the end.
Thte \pitch= changes the pitch of the speech. I made it very deep at the end.
Here's a more in depth explanation of some of these tage, taken from the Adobe Captivate blog:
"
The following commands allow the quality of the output voice to be controlled by modifying its rhythm, intonation, volume and timbre. The output speech is modified from the word following the command, up until the end of the prompt.
Speed Control: Allows the speaking rate to be modified, expressed in an abstract scale 0-100.
\speed=<num>
Example:
\speed=60 (Scale 0-100)
\speed=60 This text is read at a faster speed.
Pitch Control: allows the fundamental frequency (tone or pitch) to be modified, expressed in an abstract scale 0-100
\pitch=<num>
Example:
\pitch=60 (Scale 0-100)
\pitch=60 This text is read at a 60Hz frequency rating.
Volume Control: allows the volume (loudness) to be modified, expressed in an abstract scale 0-100 or in decibels (dB).
\volume=<num>
Example:
\volume=60 (Scale 0-100)
\volume=60 This text will be read at a 60 decibel rating.
Timbre Control: allows the voice timbre to be modified by a shift in frequency, expressed in an abstract scale 0-100.
\timbre =<num>
Example:
\timbre=60 (Scale 0-100)
\timbre=60 This text is read at a timbre value of 60.

If you haven't installed the improved voice to text voices, get them off of the "Extras" folder on the Captivate install CD or download them here:

Look for the install links for windows and mac below the trial link.
