This product was introduced recently at the CES in Las Vegas, and it appears that it may be an improvement over similar products such as Google Translate - https://www.timekettle.co/products/fluentalk-t1-handheld-translator-device . I haven't used the device yet, but may try it if I get the opportunity.
These products will undoubtedly continue to improve and perhaps one day in the near future, they will be able to understand more of the complexities and dialects of different languages. I imagine that AI will increasingly be used in translators.
