In CRS 3.5, the language specified for a TTS request differs from the language used by TTS

Core Issue

Text-to-Speech (TTS) uses a fallback mechanism if a specified language is not available. This mechanism can cause the language specified to differ from the language used. These are the possible fallbacks:

  • If the specified language is US English or Canadian English and if US English is available, US English will be used as the fallback language. If US English is not available, and only UK English is available, UK English will be used as the fallback language.
  • If the specified language is UK English or Australian English and if UK English is available, UK English will be used as the fallback language. If UK English is not available, and only US English is available, US English will be used as the fallback language.
  • If the specified language is any other version of English and if any one English is available, it will be used as the fallback language. If both US English and UK English are available, US English will be used as the fallback language.
  • If the desired language is any other language, the European continental version will be used as the fallback language, if it is available. If it is not available, an error occurs.

Resolution

There is no resolution; TTS is working as designed.
