The Speech Designer is a static call flow, each caller moving through the same call flow as defined in a project. Normally, choices made by the caller can not be exported to a database; however, with the CAPI, all this can be accomplished and more. Each time a caller enters a module the speech application performs a recognition and confirmation, after which an event can be fired. The Custom Action DLL can perform such tasks as add audio, make additions to the grammar, evaluate previous recognitions, direct the caller to a new module, or transfer the caller.

The power of the Designer is greatly increased when the Custom Action DLL attaches to a database.

The Call Handler supports a variety of Intel Dialogic telephony cards, and is designed to make hardware setup as easy as possible; this allows more time for you to develop and test your speech application.

When developing your speech recognition application with the Speech Platform's Designer, run tests by clicking on the Test button in the Toolbar. The Call Handler allows you to use speakers and a microphone to completely test your application in-house-before releasing it to customers.
