Live caption doesn’t work for iPhone, Cantonese captions are wrong

Using an iPhone 15, cannot make live caption for any language after a few days of playing around with iPhone settings……

Update：it works for iPad

I also noticed the live caption for Cantonese is completely wrong, as the system took it as Mandarin Chinese.

Love this

Awesome app for language learners. The operation page is very simple and has no ads. With a few touches of the screen, you can turn podcasts in your chosen language on or off. In addition, you can choose landscape/vertical screen, and you can choose to turn on subtitles. Subtitles and voice are synchronized. Help to learn languages ​​more immersed.
