Limits on the TRUSTED_CLIENT_TOKEN #21

Closed cmalzatet closed 1 year ago

cmalzatet commented 1 year ago

Hi! I would like to ask if there is a limit to the TRUSTED_CLIENT_TOKEN used in the library, like number of synthesis or somethign like that.

Thank you for your help.

TRUSTED_CLIENT_TOKEN is the same as the one used in the Microsoft Edge browser, so there shouldn't be any noticeable limits if you're using it normally. The only limit with the API I was able to find is that it starts returning 429 if you flood it with 500 connections in parallel, but if you stay moderate about your # of connections and have some cooldown time between bursts then it would be fine.

Any 429 block is temporary and goes away in 5 minutes.

Also you can't use any of the Azure Cognitive Services features anymore (unless they are also accessible in Microsoft Edge), so for example expression/emotion, background audio, other MS SSML additions are not possible. They had blocked them a while ago, though there might be some workaround; not that I'm keen on finding it, seems like a pointless cat and mouse game.

Tested on 2495 consecutive short requests. One error on 416. Reliable enough.
