Hello @jon schmidt
Thanks for using Microsoft Q&A platform, you can use the audio files and text generated from TTS or STT for commercial use, but please ensure below:
1.You are using a speech resource that is billed for your valid 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 can but you should consider upgrading to Pay as you go since free tier might not be a scalable solution.
2.You can't use our AI output to recreate an AI model
3.You must follow our code of conduct - https://learn.microsoft.com/en-us/legal/cognitive-services/speech-service/tts-code-of-conduct
I hope this helps.
Regards,
Yutong
