- WhatsApp already does it, on-device. Settings → Chats → Voice message transcripts, long-press a voice note → Transcribe; the audio never leaves the encrypted chat.
- It fails predictably and can't translate. Noise, slang and mixed languages mangle the text, and a transcript in a language you don't read stays unreadable.
- InterMIND keeps the whole conversation in each side's language: when voice notes are really a conversation, move it to a call where each side speaks and hears their own language. Guests join free by link, no account.
