The'world's first' AI-powered hearing aid connects to your smartphone and can translate speech into 27 different languages, say its creators. Experts claim to have mastered near-real time translation of Arabic, Japanese and French, among others, by listening for the foreign language and relaying it to the phone. The device is akin to the fictitious alien Babel fish that performs instant translations in comedy science fiction series The Hitchhiker's Guide to the Galaxy. Creators Starkeys claim the technology reduces noisy environments by 50 per cent, while artificial intelligence optimises the hearing experience and its translation is compatible to Google Translate in terms of accuracy. The Livio AI, which is now on sale in the UK and costs £3,000 ($3,900), also has brain tracking technology and Alexa connectivity, and interfaces with the mobile app, Thrive Hearing.
