Using Microsoft TTS for commercial use

Question

Hi, can anyone tell me if using Microsoft's TTS voices for commercial use without a license?

Answer 1

You need to buy license, When you buy a Windows (or Office) license you are granted the right to use it to generate outputs of various types. What you can't do is resell the basic tools. Without license you can’t use Microsoft's TTS voices for commercial use
