Chapter 8 Troubleshooting Tips
Text-to-Speech (TTS) Problems
A TTS prompt is not recognizable
Symptom A TTS Prompt cannot be recognized by callers.
Error Message None.
Possible Cause The language of the text does not match the Override Language in the TTS Prompt step.
For example, the text is in English, but the Override Language is Spanish.
Recommended Action In the appropriate TTS Prompt step, make sure that the Text Input matches the
Override Language Selection.
MRCP TTS subsystem is out of service
Symptom The Engine Status area in the Engine web page shows that the MRCP TTS Subsystem is out
of service.
Error Message None.
The cause could be one of the following:
• The MRCP Provider and Server are not configured from the MRCP TTS Configuration web page.
• The MRCP TTS Server(s) is down or unreachable.
Complete the following steps:
Step 1 Verify that MRCP Provider and Servers are configured through the MRCP TTS Configuration web page.
Step 2 Verify that the MRCP TTS servers are up and reachable.
Long TTS prompts consume significant memory on CRS Server
Symptom Long TTS prompts consume significant memory on the Cisco CRS Server.
Error Message None.
Possible Cause Long text files will increase memory usage on the CRS Server. For example, a 5 KB text
file requires a 2.5 MB audio file. On a system with 40 TTS ports, this scenario can consume
approximately 120 MB of memory.
Recommended Action If you are using long text files, make sure to provision your system appropriately.
