How can I possibly call a person whose job is to train (not teach!) people to speak English. It's like Question-Answer, Question-Answer. They don't teach grammar, vocab, reading, writing. They only get people talking. I've been googling it for ages but nothing fits. Speaking trainer - usually refers to public speaking trainers, English speaking trainer - refers to trainers who speak English, Talking trainer - it's like for budgies... I guess, I'm not quite correct with my search inquiry. Thank you.
Try “language exchange” or “conversation partner.”
For what it’s worth, there are lots of websites and apps out there for this exact purpose, like https://www.hellotalk.com
