About Text-to-Speech

Text-to-speech (also known as Speech Synthesis) is great for IVR systems that need to speak people's names, street addresses, and things that you cannot sensibly pre-record as prompts. It’s also useful if you use pre-recorded prompts that you expect to change regularly.

SQLphone uses SAPI (the Microsoft Speech standard) to carry out text-to-speech. SQLphone supports SAPI version 4 and version 5 standards.

To use text-to-speech in your IVR system, you need a Speech Engine. If you are running Windows 2000/XP/2003, you already have the Microsoft speech engine installed. Just select Text-to-speech from the SQLphone Connect menu, then select the Microsoft voice -- you are now ready to use text-to-speech in your IVR system.
