Azure Text-to-Speech - Saving Files and Distrbuting the Files

Hello,

I have a system where there is a backend server that needs to create Text-to-Speech audio and command client machines to play that audio. The client machines are not garnetted to always be connected to the internet. or backend server In the majority of cases, the audio needs to only be created once and will be used multiple times by the client machines.

So, I would like to use the Azure Cognitive Text-to-Speech service (https://azure.microsoft.com/en-us/services/cognitive-services/text-to-speech/) to request text-to-speech audio. That audio would then be saved as files on a backend server. These files would then be distributed to client machines over our intranet infrastructure. Finally, the files would then be used by the client machines to play audio. This system is basically ensuring that the audio can be played by the client machines without the internet.

My question is, will I be breaking any terms of service by saving the audio created by the text-to-speech service and disrupting the files?

Thanks,
Justin
