Text-to-Speech was a new feature of Captivate 4. The idea is to type the voice-over narration in the Slide Notes panel and have Captivate convert it to a sound clip. To convert typed text to sound clips, Captivate uses some preinstalled voices called Speech Agents.

If you do not have an installation DVD available, you can download the Speech Agents ...
