i generally do too. but on the other hand hiring a voice actor is cost prohibitive for someone just starting out and even asking a friend will multiply the amount of effort unless you want to do this as equal partners where the better speaker simply gets more airtime and the other does more of the research.

as an alternative maybe it helps to explain the reason up front. not being able to speak is a good excuse and i wouldn't want to miss out on good material just because the creator has no voice.

for someone who is simply not speaking english well enough, practice and get better.

as an alternative, record the video in your native language and offer the computer voice in english as a second audio track. then we can tell the difference from AI slop.
