Upgrade to Text-to-Speech Neural Voice by 31 August 2024
Published date: August 17, 2021
Text-to-Speech currently supports both standard and neural voices. However, since the neural voices provide more natural sounding speech output, and thus, a better end-user experience, we are retiring the standard voices on 31st August 2024 and they will no longer be supported after that date.
Here is a quick comparison between Standard Text-to-Speech and Neural Text-to-Speech features：
Natural sounding, closer to human-parity
Limited capabilities in voice tuning
Advanced capabilities in voice tuning
No new investment in future voice fonts
On-going investment in future voice fonts
To make the change, follow the steps to update the voice name in your speech synthesis request to the supported neural voice names in chosen languages by 31 August 2024. Starting 1st September 2024, standard voices will no longer be supported, please use neural voices for your speech synthesis request, on cloud or on prem.
