Azure Cognitive Speech TTS Custom Japanese Non-Neural Voice Unavailable

淑纓 楊 21 Reputation points


I'm on the S0 Tier for Azure Cognitive Speech services and am trying to train a custom voice for Japanese TTS. My data was successfully processed. But I wasn't able to select "Statistical Parametric" or "Concatenative" as my training method. "Neural" was the only option on the list.


However, I was able to use those non-neural methods for English and Chinese projects.


I'm aware that non-neural custom voices are being deprecated but I don't see any information on the documentation about them being disabled in certain languages.

Does anyone know if I could still train a Japanese non-neural voice model? If so, how?

Thank you very much in advance.

    Hello @淑纓 楊

    I just got confirmation that Non-Neutral voice training has been deprecated.

    To answer your question about why you can train non-neutral voice model for some languages but not for Japanese: We allow current users to re-train non-neural voices for their existing projects, but they are not allowed to train new voices

    For user use non-neutral, we have a short guidance to help you mitigate to neutral training:

    Sorry for the inconvenience.
