Live dubbing means the other person in your call hears a spoken, translated voice — something close to real time. Live captions mean they only see translated text on screen; your own voice reaches them completely unchanged. The distinction matters because most software marketed as "real-time meeting translation" is actually a captioning tool, not a dubbing tool, and the two solve different problems.
Two different products, one overlapping name
Searching for "live dubbing software" tends to surface generic offline audio-editing tools — waveform editors, post-production video-dubbing utilities — because "dubbing" is an overloaded term. Traditional dubbing translates a finished recording well before anyone watches it: a studio records a new voice track, syncs it to picture, and ships the result. Live dubbing translates a conversation as it happens, with no time to iterate or re-record. They share a word and almost nothing else.
Meeting-translation tools have their own version of the same confusion: many of them display translated text in real time and call that "live translation," which is accurate but easy to mistake for dubbing if you're not looking closely at what actually reaches the other person's ears.
What each one actually gets you in a meeting
Captions: the other participant reads translated text scrolling on their screen. Their own listening experience of your voice doesn't change at all — they still hear your original language, unchanged, and read the translation alongside it (or not, if they're not watching the caption feed).
One-way dubbing: you hear the other party's speech translated and spoken aloud, with their original voice ducked (lowered, not muted) underneath so tone and emphasis aren't lost entirely. This is what Voxis's Video & Game mode does for one-directional content.
Two-way dubbing: both directions get spoken audio. You hear the other party translated, and — if you want it — your own voice gets translated and sent back through a virtual microphone, so they hear you speaking their language, without installing anything on their end. This is what Voxis's Meeting mode does.
| You hear | They hear | |
|---|---|---|
| Captions-only | Translated text on screen | Your original voice, unchanged |
| One-way dubbing | Translated speech | Your original voice, unchanged |
| Two-way dubbing | Translated speech | Their own language, spoken |
When captions-only is genuinely the right call
Two-way dubbing needs a virtual microphone installed so translated audio can be routed back into the call as if it were a real mic. If none is installed, Meeting mode degrades gracefully to listen-only — you still hear the other side translated, you just aren't translated back to them, and the app labels this on screen so it's never a silent surprise. For one-way content — a recorded video, a livestream, anything you're only watching — captions were never really competing with dubbing in the first place; that's a different mode (Video & Game) built for exactly that case.
FAQ
Does dubbing replace my microphone entirely? No — a virtual microphone is added alongside your real one, and you choose which one the meeting app uses. Nothing about your physical mic setup changes.
Does anyone see a bot join the call? No. Audio capture happens locally on your own machine and is never sent to the meeting platform as a separate participant — there's no bot account, no join request, no visible integration at all.
Can I use dubbing in only one direction if I don't need both? Yes — hearing the other party translated needs no extra setup; sending your own voice back is the optional half that requires the virtual microphone step.
