Hi @Tisha Aggarwal,

When using the Azure Speech SDK for pronunciation assessment, the feature is currently only available for the "en-US" locale. As a result, when setting the language to "en-IN" or other non-"en-US" languages, the phoneme assessment might return a blank JSON response. This limitation is due to the fact that prosody and detailed phoneme assessment are not supported in languages other than "en-US."

To resolve this, you can use "en-US" for full pronunciation assessment capabilities. For more info, please refer this document.

I hope you understand! Thank you.
