Listening to vocabulary at normal and slow speeds: The app provides a large number of audio examples, allowing children to listen to accurate Cantonese pronunciations and choose slower speed pronunciations for a clearer understanding of speech details. 2. AI pronunciation comparison feature: CanTone utilizes advanced AI technology to automatically analyze and evaluate children's pronunciation, providing immediate feedback to help them continuously improve. 3. Encouragement mechanism: The app employs a system of positive reinforcement, providing encouraging responses regardless of the child's pronunciation accuracy.
