@Newstart Yes, you can use the audio files and text generated from TTS or STT for commercial use. Please ensure you are using a speech resource that is billed for your subscription. The billing will be based on the pricing as mentioned in the pricing page. If you are using a free account or credit you should upgrade to Pay as you go and use the selected tier.
You need not seek permission or license or pay loyalty to MS for using the output files generated from your resource as long as you use your own content as input to the service. Please ensure to follow certain responsible guidelines listed here while using synthetic voices in your applications and ensure proper disclosures.
You can look up more details about the compliance and privacy terms from here.
To summarize answers to your questions:
- Can I use it for Commercial Purposes? "Earn money through Freelancing Platform"? Yes
- Did I have the Right or License to use it? No, as long as you are using your own resource and content
- I saw a lot of Freelancers using it as well, and they say there's no need to pay because "it's free." The resource under free tier is only up to a certain limit. For all commercial purposes you will have to change the pricing to standard tier. Also, use a pay as you go type subscription. Free credit subscriptions should not be used for commercial purposes.
I hope this helps!!
