Translation

translations is a list with one entry per target language. Leave it out, or send [], to only transcribe.

"translations": [
  { "language": "es", "engine": { "@type": "Gemini" } },
  { "language": "de", "engine": { "@type": "DeepL" } },
  { "language": "pt-BR" }
]

Field
`language`	required	The target language.
`engine`	optional	The translation engine. Left out, the recommended engine for the language is used (`pt-BR` above).
`ttsOptions`	optional	Dub this language. See Dubbing.
`outputLabel`	optional	The label written where an output has one; the language’s English name by default.

A translation only produces something when an output uses it: a dub track (if it is dubbed), a subtitle track or a subtitle file in that language.

Engines

`@type`	Engine	Good for
`Gemini`	Google Gemini (LLM)	Natural, context-aware translation, speaker-gender aware. A strong default for dubbing.
`OpenAI`	OpenAI GPT (LLM)	The same, with GPT models.
`Nova`	Amazon Nova (LLM)	The same, with Amazon’s model.
`DeepL`	DeepL	Fast, literal, excellent for European languages.
`Google`	Google Translate	The widest language coverage.
`Soniox`	Soniox	Pairs with Soniox transcription.
`NoTranslation`	None	No machine translation: the source text is passed through.

{
  "@type": "Gemini",
  "model": "Gemini 3.1 Flash Lite",
  "extraPrompt": "Informal register, as spoken between friends. Keep fishing terminology in English.",
  "glossary": { "crankbait": "crankbait", "Fishing Channel": "Fishing Channel" }
}

Field	Default
`model`	Gemini: `"Gemini 3.1 Flash Lite"`; OpenAI: `"GPT-5.6 Luna"`; Nova: `"Nova 2 Lite"`	Models listed by the schema of your build.
`extraPrompt`	`"Avoid profane language in translated output."`	Instructions for style, register, audience. Replaces the default, so restate it if you want to keep it.
`glossary`	none	Terms with a fixed translation, see below.
`compression`	`true`	Condense long translations, which keeps a dub in step with the original speech.
`latencyMode`	chosen for the recognizer	`quality` translates whole sentences; `low-latency` smaller units.

DeepL, Google, Soniox

These take a glossary only.

{ "@type": "DeepL", "glossary": { "Newsmax": "Newsmax" } }

Glossaries

A glossary maps a source term to the translation it must have. Use it for names, brands and terminology that must not be translated or must be translated one way:

"glossary": {
  "Fishing Channel": "Fishing Channel",
  "largemouth bass": "lobina negra"
}

Or name a glossary of your account by its id. It must translate from the transcription language into this translation’s language, and it is read each time the project starts (Your account’s dictionaries):

{ "language": "es", "engine": { "@type": "Gemini", "glossary": 17 } }

Several languages at once

Each entry is independent: mix engines, and dub some languages but not others. Here Spanish and German are dubbed, French is subtitled only:

"translations": [
  { "language": "es", "engine": { "@type": "Gemini" }, "ttsOptions": { "provider": { "@type": "Deepdub", "voice": "auto" } } },
  { "language": "de", "engine": { "@type": "Gemini" }, "ttsOptions": { "provider": { "@type": "MultiVoice" } } },
  { "language": "fr", "engine": { "@type": "DeepL" } }
]
