Can Alexa translate in Live? yes , It can. Alexa is getting the ability to do live translations between English- Spanish, German, French, Hindi, Italian, and Brazilian Portuguese with the new update.
This new feature can be initiated with a voice command like “Alexa, translate Spanish”. The update joins Alexa’s expanded multilingual skills that were added in November to make the assistant more capable non-English speaker.
In support of the new skill, Amazon also says it modified Alexa to better handle natural pauses in conversation. This mode is very similar to Google Assistant’s interpreter Mode which was originally launched in 2019 and it is able to translate up to 27 different languages. Amazon says Alexa Live translation is available now on Echo devices in US. According to https://www.theverge.com/2020/12/14/22174561/amazon-alexa-live-translation-google-assitant-interpreter-mode
