Is there any language limitations for SSML support? (not working for Bangla)

Question

When we try to use the SSML tags for the Bangla (Bangladesh) or the Bengali (India) TTS models, they utter the speeches plainly, ignoring the SSML tags. For example, the say-as elements don't work for these models, but they work for the English models. Can you please let us know if this is due to a language limitation or not? If yes, we have a couple of follow-up questions:

1. Which SSML features are currently supported for the Bangla/Bengali models?
2. When can we expect the other features to be supported?

Our use case is highly dependent on the SSML support, so it'd be very beneficial for us to learn whether we can move forward with Azure's Bangla TTS models or not. Thank you.

@sheikh.asif.imran Thanks for the question. Phonemes are not supported for the locale Bangla or Bengali of the neural voice. These will be supported in the near future.
Here is the document for language support.
