Question on using Apple TTS voice (commercial use and license)

Apple provides a function to create TTS voice as a file in TTS. (AVSpeechUtterance/AVSpeechSynthesizer)

Or, if the user records the video of TTS playback and uses that video

I wonder what the scope of use is if I use this TTS voice to make YouTube, TikTok, or commercial videos.

  1. Is it impossible to use it commercially at all?

  2. Can I use it commercially with the source indicated?

  3. Can I use it commercially without a separate source indication?

  4. Is there a difference in commercial use license between Siri voices and regular TTS voices?

** Added **

I was able to confirm that the license for the "Personal Voice" item in the iOS18 document of SLA prohibits commercial permission.

I would like to know if I can use voice files generated with the default TTS voices provided by Apple, or videos or voice files recorded (or screen recorded) of TTS voice playback for commercial use, other than "Personal Voice".

(Voice generated using AVSpeechUtterance and AVSpeechSynthesizer APIs on iPhone or iPad)
