This paper will introduce the methods of language training for deaf children, including breathing training, mouth and tongue training, nasal training, voice training, phoneme training, pinyin training and four-tone training.

Respiratory training

Breathing training includes deep breathing and vocal training. For example, smelling flowers, blowing balloons and saying a few words at a time.

Tongue and tongue training

Tongue training includes opening mouth, sticking out tongue, pushing tongue, rolling tongue, swinging tongue and licking mouth.

Nasal training

Nasal training can make children feel the vibration of their noses when they are nasalized.

Sound training

Voice training includes beep, beep, mom, hair, pull, hair, lulu and so on.

Phoneme training

Phoneme training includes pronouncing vowels and consonants well.

Pinyin training

Pinyin training enables deaf children to master Chinese Pinyin and learn to speak Mandarin, laying the foundation for future pronunciation literacy.

Four tones training

Four-tone training first teaches one, four tones, then three tones, and finally two. After long-term pronunciation training, deaf children can speak with sounds and tones.
