This documentation is for CCXML 1.0-Voxeo, which has been superceded by CCXML 1.0-W3C. The CCXML-Voxeo platform is not being updated any longer. The CCXML 1.0-W3C version, however, has many new features and is actively being enhanced. If you're writing a new CCXML application, you should use CCXML 1.0-W3C.

Voxeo's Enhanced Text-To-Speech Guide

If you are looking to further refine your TTS output, this guide will give you all the knowledge that you need to fine-tune your applications for more naturalistic voice prompts. Voxeo currently uses the Speechify 2.0 engine for the Staging and Production environments, and this section will show you how to use TTS markup to add the final polish to your applications.


TTS Voices

Currently, we offer not only US-English voices, but also French and Spanish, (female), should you desire to deploy a multi-lingual application. The current options available are:

To change the default voice in CCXML, you will either want to call the appropriate TTS voice from within a VoiceXMl dialog, or, if using any of the CCXML dialog extensions, you would use the 'voice' attribute:


<dialogstart src="'http://MyServer.com/MyFile.wav?termdigits=*#&amp;text=Here is my groovy male voice&amp;voice=English-Male2'" type=" 'application/x-fetchdigits' "/>
