server.mrcp2.rsspeechsynth.audioThreadNumber

Specifies the number of sending threads.

Value

Integer

DEFAULT: 20

How to set

If using the Management Station, set on the Speech Server service. If not using Management Station, set in an NSS configuration file (user-NSSxx.txt).

Usage

Occasionally changed.

Use this parameter to tune text-to-speech quality.

If applications detect gaps in audio prompts played to users, or if network analysis indicates dropped audio packets, then increase this value for better audio quality. The optimal value depends on the power of machine you’re running on and how intensive the application’s use of TTS.
