When I was still using OpenAI, I used it among other things to translate from English to Spanish while talking to Spanish-speaking people in person.

I understand a bit Spanish but I don’t speak Spanish yet, and they don’t speak English.

I speak English to the AI and end with “translate to Spanish, translation only”, and then the AI says the thing I was saying in Spanish (not perfect but good enough, and also it has a slightly weird accent that might be it using English or English influenced text to speech even when speaking Spanish sentences?).
