Error with speech to text api v3.2

Question

Hi, we recently migrated from speech to text api v3.1 to v3.2. Experiencing the following error, I understand that the new api is in preview and this could happen, but i cannot find any documentation regarding rates and limits for the v3.2 api version. Also, in policy id it says "ResourceRateLimitBy10s", does that mean that it only allows for one call every 10 seconds??

Any help is appreciated,

Thanks!!

Thanks for reaching out to us. The error message you are receiving is due to hitting the rate limit for your current pricing tier with Azure's Cognitive Services for the Speech to Text API v3.2-preview.1. The rate limit is a restriction on how many API calls you can make within a specific time period.

The policy id "ResourceRateLimitBy10s" does not mean that it only allows for one call every 10 seconds. Instead, it refers to the rate at which your resources are being limited. The specific limits are not provided in the error message and could vary based on the pricing tier you are on.

However, the error message does indicate that you should retry after 1 second, which suggests that the rate limit is fairly high. Also, it suggests that if you need a higher rate limit, you should contact Azure support service for assistance.

Unfortunately, as you've mentioned, the documentation for v3.2 is in preview and may not provide specific details regarding rate limits.

In this case, please let us know if you want a free support ticket to help you check on the limit, since we have no idea about your limit information.
