What is live broadcast translation?

Live broadcast translation is the real-time translation of a live stream or broadcast into other languages. Klassifier recognizes the speakers' words as they talk, translates them and delivers the result with a short delay as a natural AI voice and live subtitles, so viewers can follow the programme in their own language, on their own phone or in the stream itself.

The challenge

A live audience speaks many languages

Live events, webinars, sports, news and services reach people far beyond one language. Human interpreters for every language and every broadcast are hard to arrange and costly, so most live content is offered in one language only.

Our solution

Every viewer in their own language, live

Klassifier listens to the live programme audio, recognizes the speech, translates it and delivers it with low latency as synthetic voice dubbing, live subtitles or both, in several languages at the same time.

Features

Live speech recognition

Speech is transcribed as it is spoken, sentence by sentence, as the basis for translation and subtitles.

Real-time translation

Each sentence is translated into every language you choose, with a short delay behind the speaker.

Synthetic voice dubbing

Viewers hear the translation spoken by a natural AI voice instead of reading it.

Live subtitles

Show translated subtitles alongside or instead of the voice, for viewers who prefer to read or watch without sound.

Broadcast mode with emotion

In broadcast mode, the translated voice follows the speaker's emotion and energy, so commentary and speeches keep their character.

Speaker diarization

Different speakers are told apart, so panels, interviews and commentary teams stay easy to follow.

Live broadcast translation: frequently asked questions

How is this different from AI conference translation?
AI conference translation is designed for audiences at an event venue or online session. Live broadcast translation applies the same real-time technology to streams and broadcasts, with options such as the broadcast mode voice and output into your stream.
Can I translate into several languages at the same time?
Yes. You can choose several target languages for the same broadcast, and each viewer picks the one they want.
Do viewers hear a voice or read subtitles?
Either or both. You decide whether to offer AI voice dubbing, live subtitles, or both together.
How much delay is there?
The translation follows the speaker with a short delay, since each sentence has to be heard before it can be translated. The exact delay depends on the languages and the setup.
Do I need to change my streaming equipment?
No. Klassifier works with the audio from your existing production or streaming setup, and our team helps you connect it.
Can it handle several speakers?
Yes. Speaker diarization tells different speakers apart, which helps with panels, interviews and commentary.
