Amazon today announced a new Alexa feature, Live Translation, that will translate conversations between people who speak two different languages. The feature uses Amazon’s speech recognition technology and neural machine translation technology to work, and supports translating between English and French, Spanish, Hindi, Portuguese (Brazilian), German, or Italian.

To use Live Translation, an Echo device owner can issue a voice command like “Alexa, translate French,” to get started with translating between English and French. When you hear the beep, you can speak in either language, even taking natural pauses between your sentences, Amazon claims. Alexa will then automatically detect the language being spoken and translate each side of the conversation. On Echo Show devices, you can also see the translations in addition to hearing it.
