Text-to-speech audio in an application sounds like static

The problem occurs when Blueworx Voice Response 4.2 or 6.1 is connected to WebSphere Voice Server 5.1 or 6.1.1 which is using a 22 KHz TTS voice.

The cause is that Blueworx Voice Response does not support the 22 KHz TTS voice. Change the application or its configuration to use the 8KHz TTS voice.
