No pronunciation for ipad app

Ipad 5, ios14.8
After clicking “play” button, no sound.
Could anyone help?

Sound playing works on my iOS device. If you are still having trouble, have you made sure a voice is installed? Text to Speech - AnkiMobile Manual

Are you using iPad as well? It works well on my iPhone… but not my iPad

Problem solved after I selected another text to speech voice. Thanks for your help!
