Sure. This option exists in the Avatar Studio, which is the enterprise version of SitePal.

The Avatar studio, like SitePal Platinum, offers unlimited usage & access to advanced APIs, but it also offers improved data management for characters, audios and backgrounds for customers who have professional needs. 
The product also enables the ability to create and manage individual administrators, and direct access to a support representative.

Please send a note to sales@oddcast.com for pricing information.

Alternatively - if you are only interested in TTS audio, without our speaking characters, check out our vocalware product at www.vocalware.com.

Hope this helps,

Hi Ray!

You would want to use the API callbacks to coordinate.

Check out the API Reference documentation for vh_talkEnded.

You also need to load the characters into separate iframes to be able to individually control them.

We have a code example doing so - please check it out - 

http://www.oddcast.com/support1/conversation.html

and let me know if any questions.

Best,

Gil

Hi Miral - 

SitePal is not intended to be used to generate individual audios & download them.

We have a different product for TTS Audio - see - www.vocalware.com

Vocalware Export Edition supports downloading the audios (e.g for use in your videos etc.).

Please write to sales@oddcast.com for pricing information.

Best,

Hi Rich - 

You can use SSML tags to control the rate of speech.

Example - 

 <prosody rate="slow"> this is speaking slowly <prosody rate="fast"> this is speaking fast </prosody> back to slow </prosody>

You can also use percentage values for more precise control - 

Example - 

 <prosody rate="-25%"> this is speaking slowly <prosody rate="+25%"> this is speaking fast </prosody> back to slow </prosody>

This information & more can be found in the API reference do - see Appendix C - 

http://www.oddcast.com/support/docs/vhost_API_Reference.pdf

Note that SSML tags are only supported for voices from Engines #2 and #3.

Hope this helps,

Gil
