I tried out Otua. Although English and French aren't my native languages, I couldn't test its full potential, but it perfectly picked up my pronunciation and generated clear captions. As a person with a hearing disability myself, I can see this being incredibly helpful when traveling to English or French-speaking regions.

The features and UI are very well designed. If I could offer just one suggestion from the perspective of someone who is hard of hearing, it would be "name detection." One of the most challenging situations for us is not realizing when our name is called. It would be amazing if we could pre-register our name and have the phone and smartwatch vibrate when it's spoken.
