Hi @Peter Mwansa,
Thank you for reaching out to Microsoft Q&A forum!
The changes in the "Brian" voice are due to Azure AI Speech updates that introduced multilingual support and altered voice characteristics. While these updates aimed to improve quality, some users have found the voice to be more monotonous. Additionally, Azure retired the Standard Voice, encouraging a shift to Neural Voices.
If the changes affect your use case, submit feedback via the Azure Feedback Forum. Here's the link to the Azure Feedback Forum: Post idea · Community (azure.com). Additionally, review and test the new voice models and styles to see if they align with your needs.
For more info, see: Azure AI Speech Release notes and consider exploring alternative voices or settings.
I hope you understand. Do let us know if you any further queries.
