Chapter 8 Troubleshooting Tips

Text-to-Speech (TTS) Problems

Provider becomes IN_SERVICE immediately

Symptom When creating as ASR/TTS provider, its status becomes IN_SERVICE immediately. This happens even before creating any servers for it.

Error Message The ASR/TTS provider status incorrectly showsIN_SERVICE.

Possible Cause After deleting a provider and all the servers along with it, if a new provider is created, it continues to use the previous configuration and does not get refreshed.

Recommended Action Click Refresh or Refresh All for that provider. This will cause the status of the provider to go OUT_OF_SERVICE as expected.

A TTS Prompt will not play

Symptom Callers do not hear a TTS prompt when a TTS prompt is expected.

Error Message None.

The cause of the problem might be one of the following:

•The language specified in the Override Language field in the TTS Prompt step is not available.

•The text referenced in the Text Input expression is larger than 20 KB.

•There are not enough MRCP TTS licenses for the MRCP TTS Provider that is being used. Licensing can be implemented in different ways by different MRCP TTS vendors. It may happen that depending on the licensing scheme of the vendor there may not be enough MRCP TTS licenses configured for the language being used.

•When using multiple TTS providers, each with a different set of supported languages, the appropriate TTS provider (the one that supports the desired language) might not get used. This might be because the provider is not selected as the Default TTS provider and therefore some other provider might get used.

Recommended Action Depending upon the cause, do one of the following:

•If the language specified is not available, from the CRS Administration web page, choose Subsystems > MRCP TTS and check whether the MRCP TTS server for the Override Language is configured. If it is not, configure a new MRCP TTS server with the desired language and then reload the corresponding MRCP Provider.

•Text larger than 20 KB is not allowed. Make sure that you are using less than 20 KB of text.

•If necessary, obtain a license for additional MRCP TTS ports from the MRCP TTS vendor.

•If the default TTS provider is not being used, configure the Default TTS Provider field using CRS Administration. Go to System > System Parameters and select the desired TTS provider. Or using the CRS Editor Create TTS Prompt step, explicitly specify the desired TTS provider in the Overrride TTS Provider field. If using VXML scripts, specify the desired TTS provider for Nuance Vocalizer 3.0, and the configure it as follows:

•<property name="com.cisco.tts.provider" value="Nuance Vocalizer 3.0"/>
