Live captions, translations and voice dubbing for live streams

Send one feed to StreamShark and it can come out captioned as the words are spoken, translated into the languages your audience needs, from a choice of 30+, and re-voiced in natural-sounding AI voices. Viewers select from the languages you enable for the event, and the captions and dubbed tracks stay with the replay.

How live captioning, translation and voice dubbing work on StreamShark

Live captions are a text transcript of the presenter, generated as they speak and shown in the player synchronized with the video. Live translation turns that transcript into other languages, and live voice dubbing voices each translation with an AI voice. All three run on the live stream itself, on the backup ingest as well as the primary and on streams protected with Hollywood-grade DRM, and caption and dubbing usage shows up in analytics for customers on the CMCD dashboards. Live captions, translations and voice dubbing require an Enterprise plan.

Live captions on every stream, from the moment you go live

Switch captions on when you set up the event and your feed is transcribed as it arrives.

Synchronized captions

Captions appear on screen as the presenter speaks, so viewers reading along stay with the room.

A fully automated workflow

Once captioning is enabled, your only step is to send your feed. StreamShark transcribes the audio, times the captions and delivers them to the player.

Custom vocabularies for names and terms

Load speaker names, brand names and product terms before the event and they are spelled correctly on screen the first time they are said.

Built-in accessibility

Live captions make your stream accessible to deaf and hard-of-hearing viewers, a step toward accessibility standards such as WCAG and the ADA.

Live translation into the languages your audience speaks

Translation runs from the live captions as they are generated. You choose which languages to enable for the event, and each viewer selects one of those from the player.

Translation without a second workflow

Choose the target languages when you set up the event and there is nothing else to operate during the stream.

A language menu in the player

Everyone watches the same stream and reads along in the language they picked, without you running a separate stream per language.

Non-Latin and right-to-left languages

Chinese, Japanese, Korean, Arabic and Hindi are covered, and human review of the translations is available as an option for events where every word matters.

Multilingual voice dubbing, so viewers listen instead of reading

Live voice dubbing takes the live translations and voices them in natural-sounding AI voices as the stream runs, with each language as its own audio track in the player.

Natural-sounding AI voices

International viewers hear the town hall or keynote in their own language and keep their eyes on the slides instead of reading subtitles.

The original audio underneath

A dubbed track lowers the original speaker rather than removing them, so viewers still hear the presenter's tone and the room.

Dubbed tracks saved to the replay

Every dubbed track is saved with the recording, so the replay offers the same languages the live stream did.

Live captions, translation and dubbing questions we get asked

You enable live captioning when you set up the event and send your feed as usual. StreamShark passes the audio to the captioning engine it has set up for the event, and the transcript comes back into the player synchronized with the video. Viewers switch captions on from the player, and a custom vocabulary of names, brands and product terms can be loaded beforehand to improve accuracy.

Live translation covers 30+ languages, including Chinese, Japanese, Korean, Arabic and Hindi. You choose the target languages when you set up the event, and each viewer picks the one they want from the player's language menu.

Live. The live translations are voiced in an AI voice as the stream runs, and each language becomes a separate audio track the viewer can select in the player. The original speaker is mixed underneath the dubbed voice, and the dubbed tracks are saved with the recording so the replay carries them too.

No. Captions, translated captions and dubbed audio tracks all appear as choices in the StreamShark player. A viewer picks a caption language or an audio track from the menu and the stream carries on.

They keep running. Live captions are provided for both the primary and the backup stream, so a switch from one to the other during the event does not interrupt them.

Yes, for customers on StreamShark's CMCD analytics dashboards. Caption and dubbing analytics show how many viewers switched them on, which languages they chose and how that changed through the stream, both live and after the event.
