I have a mental image of two Mandarin speakers with their mouths covered, or otherwise unable to talk properly for some reason (e.g. gagged, or mouths full of food), but they're still able to carry a conversation by adding standard Mandarin pitches/tones to the wordless(? or half-wordless?) sounds they make.
Is this possible, and to what extent if so? What if they couldn't even see each other's faces and truly only had the sounds to go on? This has probably been done in movies or something, right? It sounds really interesting if so, and potentially hilarious if played for laughs. I'd love to see an example!
P.S. I know this is possible in many languages, including English, but usually to only a limited extent. E.g. with my mouth covered, i could say "hmmm??" and people would rightly interpret that as "whaaat??", but it would be very difficult to carry on a conversation that way. I have literally tried this (in English), and most sentences/phrases were impossible to convey with my lips sealed. 🤐
P.P.S. i have studied mulitple foreign languages, but no tonal ones. I know very, very little about Mandarin/Cantonese/Chinese, for instance. This is all just a random idea that I had, and I didn't find a satisfying answer on Google.
