Hi guys - I am seeing this weird issue with the quality of blend shapes received from TTS service. For some reason, the blend shape is not in sync with the audio at night whereas it works perfectly in the day time. I am using the southeast Asia region.

Can someone tell me how to fix this?? Should I try switching the region, do you think that should help?

    Hi @pulkit garg,

    Thank you for reaching out to Microsoft Q&A forum!

    I tried to reproduce the issue and it is working fine. It's possible that the issue you're experiencing with the blend shapes not being in sync with the audio at night could be related to network congestion or other factors that affect network performance.

    You can also try optimizing your application to reduce the amount of data being transmitted over the network.

    Before switching the region, I would recommend checking your network connection and ensuring that it's stable. You can also try testing the TTS service during different times of the day to see if the issue persists.

    If the issue persists, you can try switching to a different region to see if that resolves the issue. However, keep in mind that the availability of voices and styles may vary by region, so you may need to check the documentation to ensure that the voice you need is available in the region you're considering.

    If you're still experiencing issues, please inform us so we can conduct further investigation on this issue.

    I hope this helps. Thank you.
