    Hello @Chris Wang

    Thanks for reaching out to us, I think you are mentioning the expiration of your custom speech model right? I am sorry to hear your model loss.

    Here are timelines for model adaptation and transcription expiration:

    • Training is available for one year after the quarter when the base model was created by Microsoft.
    • Transcription with a base model is available for two years after the quarter when the base model was created by Microsoft.
    • Transcription with a custom model is available for two years after the quarter when you created the custom model.

    In this context, quarters end on January 15th, April 15th, July 15th, and October 15th.

    When a custom model or base model expires, it is no longer available for transcription. You can change the model that is used by your custom speech endpoint without downtime.

    Custom endpoint Speech recognition requests will fall back to the most recent base model for the same locale. You will get results, but recognition might not accurately transcribe your domain data. Update the endpoint's model as described in the Deploy a Custom Speech model guide.
    Batch transcription Batch transcription requests for expired models will fail with a 4xx error. In each Transcriptions_Create REST API request body, set the model property to a base model or custom model that hasn't yet expired. Otherwise don't include the model property to always use the latest base model.

    I hope this helps, sorry for the inconvenience again.

    Regards,

    Yutong
