Fluency voices fail after first playback

The information in this article applies to:

• SpeechKit 4

Symptoms

Only the first StartPlayback with a Fluency SAPI 4 voice completes, then consumes CPU.

Cause

Like the Voxit Macaw voice, the Fluency SAPI 4 IAudio interface LevelGet and LevelSet functions fail causing an incomplete ChantTTS initialization.

Status

Since Fluency and Voxit voices are based on RealSpeak technology, the original workaround for Voxit Macaw added in SpeechKit 4 build 4.0.106.0 was removed and replaced with more extensive SAPI 4 fidelity checks to address all RealSpeak-based voices. Fixed in SpeechKit 4 build 4.0.112.0.
