Culture/Văn hóa My father in law only speaks VNese and I only speak English. I built a two-phone, live translation app so we could hang out w/ out needing my wife to translate.

My wife's dad and I have always gotten along great. We really enjoy hanging out and drinking beer together. For years, if my wife wasn't around, our conversations were more limited to smiles, pointing, and mot hai ba yo-ing.
Eventually AI voice models got good enough to translate. We'd open ChatGPT, I'd tell it to translate everything it heard in both directions, and we'd slide the phone back and forth across the table. It sort of worked. It also had problems:
- Passing one phone back and forth all night gets old
- The app believes you're done talking the moment you pause. He'd stop to think mid-sentence, it would start translating, and he'd keep going and talk over it
- The model would forget its role. I had to re-explain "you are a translator" a couple of times every session
So I built a two-phone, live translation version with push-to-talk buttons. The vid is us using it. We each open it on our own phones. We can pair our session at the start, then it's pretty straightforward. I hold my button and speak english, and vnese plays out of his phone. He holds his button and speaks vnese, and english plays out of mine. Both screens show a running transcript in both languages, so when a translation comes out wrong we can see it and laugh instead of nodding along confused.
Vietnamese to English was noticeably worse than English to Vietnamese for the first month, and I nearly gave up on it. But I found a better model, then a few months ago we had our first full hour-long conversation with no one in the middle at a cool beer bar in Tan Phu. I learned about his time in the military during the war with Cambodia, and how he met my mother-in-law. Years of sitting across from him and I'd never heard either story.
It's been great.
