Frequent slow speech synthesis or ResourceExhausted: "No free synthesizer" responses

DWinkler 1

In recent days we're often receiving very slow synthesis or ResourceExhausted: "No free synthesizer" responses.

The health pages do not indicate any problems, is there a way to find the cause of this issue? (region is westeurope)

Kind regards,
Daniel

Hi, thanks for reaching out. Is this a free/paid subscription? Also, where exactly are you viewing this error, Azure Service Health?

Thanks for your feedback, it is the paid subscription.
I am getting this error as result from the synthesis service on a normal SSML request.
Sometimes the synthesis peeks to approx 15 seconds; when the next, similar request is returning in <1 sec.
(The health endpoint reports all green.)

Thanks for the information. Following up to inquire on whether you're still experiencing this issue? I'm unable to reproduce this issue in my environment. If issue persists, my recommendation is to raise a support request so engineers can perform proper diagnosis of the issue. Sorry for any inconvenience.
