Languages
A Pāṇini TTS voice is not locked to one language. The language comes from the text you type, so Mark can read any of the 250+ languages Pāṇini TTS supports, including text that mixes two languages.
Mark's accent carries over: a script in another language sounds like a American English speaker reading it. That is useful for bilingual channels; for a native sound in another language, choose a voice recorded in it.

YouTube
Yes, AI voices are allowed. What YouTube limits is mass-produced, repetitive content: videos made from a template with little original work. Its July 2025 update renamed that rule from “repetitious” to “inauthentic” content (YouTube’s monetisation policies).
Write your own script, add your own research or editing, and keep one consistent voice for the channel. Where a realistic AI voice could mislead viewers, use YouTube’s altered or synthetic content label. The monetisation decision is always YouTube’s.

Yes. Mark can read any of the 250+ languages Pāṇini TTS supports, because the language comes from the text you type, not from the voice.
