I was trying to add voice for my game and I found Amazon Polly, and I'd like to use the voice that the service outputs. However, after reading documents such as ToS, I cannot find a definitive answer on what you can do with the recordings.
Suppose that I generated a voice recording using Amazon Polly and downloaded it as an audio file.
What I want to do with this recording is:
- to add audio effects to the voice recording and
- to merge Polly recordings with other audio to reduce file count.
Is it allowed to make 'direct' derivative works (I'm not sure if that is the right word) from the recording I made with Polly like this?
Or do we always have to use the recording exactly as what Polly generated?
(Note: I have all the required licenses/copyright to use the text itself to generate the recording and the audio I want to merge with the recording.)
