Press Start, play it, and the captions appear as it is spoken — original, translated or both. If you live in Thailand part of the year, work with a team in Bangkok, or follow Thai series and live sellers, the gap is never the written language — it is speech: the condo office on the phone, the hospital calling back, a landlord’s voice message, an episode that airs with no English subtitles. Tingdong listens to whatever your Mac plays, detects Thai automatically, and floats English captions over it while the sentence is still being spoken.
Set the source to “Screen sound” so it captions the video or the call audio rather than the room. You never select Thai — it is detected.
Captions float over the player or the call window: the Thai line on top, English below, updating mid-sentence. The English can be read aloud to you instead.
Choose Tingdong Microphone in the mic menu of FaceTime, Zoom, LINE or WhatsApp for Mac, or hand an iPhone call to the Mac over Bluetooth. You speak English, they hear Thai.
Written Thai runs words together without spaces, and spoken Thai is tonal, so the first job — deciding where one word ends and the next begins — is a guess that changes the meaning of everything after it. Politeness particles and the pronoun system add information that a short, isolated line does not preserve, which is why line-by-line translations of Thai read as clipped and oddly blunt. Tingdong translates a continuous stream of speech and keeps context across sentences, so a long call with an office or a full episode holds together. Detection is per phrase among 60+ inputs, which matters because working Thai borrows English words constantly, and the Thai line is always shown above your English so a name, a number or an address can be checked rather than assumed.
Yes. It captions the audio your Mac plays, so YouTube, Netflix, a Facebook live seller or a local file all get the same floating captions — a subtitle track does not have to exist.
Yes. Hand the iPhone call to your Mac over Bluetooth and both directions are interpreted: they hear your voice plus a Thai translated voice, you read their replies as English captions, and they install nothing.
Play it in LINE for Mac with Live Listen running. Voice messages carry no captions at all, so this is often the first thing people try it on; a LINE call on the Mac uses Tingdong Microphone instead.
Names and addresses are the weakest spot for any speech system, in any language. The Thai line stays on screen above the translation so you can read it back or ask the other side to repeat, instead of acting on a guess.
No. Thai is auto-detected among 60+ input languages, per phrase, so a conversation that mixes Thai and English works without any setup for each app.
