Machine translation
Translating text from one language to another with software, without a human translator.
Machine translation uses an AI model to put a text into another language. Current models translate whole sentences with their context rather than word by word, and the result is usually fluent. Even so, they can stumble on technical terms, proper names, irony or half-finished sentences.
Subtitles add a difficulty: each subtitle is often half a sentence. Translating subtitle by subtitle produces nonsense; the right approach is to translate the whole sentence and then share it out across its subtitles.
Echo translates on its own servers. You can make a translated copy of a transcript (keeping each paragraph’s time and speaker) and subtitles in several languages at once: they’re grouped into sentences, translated whole and shared out with the same timings.
For public, legal or medical texts, have someone who knows both languages review the translation before you use it.
