Objective

2

Compare the articulation of plosives between preschool children with hearing impairments and healthy children

analyze the difficulty of plosives in different parts of hearing impairments under different air supply methods

explore the underlying reasons that affect their articulation

and provide a basis for rehabilitation training of air supply plosives.

Methods

2

104 hearing-impaired children aged 3 to 5 years who have recovered for more than half a year and 36 healthy hearing children were used to analyze the articulation of plosives in different modes of air supply using the Chinese Phonetic Ability Test Vocabulary as the test material.

Results

2

The plosives of healthy children aged 3-5 years had been learned (≥90%). The articulation of aspirated plosives was the same as that of unaspirated plosives in all age groups. The influence of different aspirating methods on the articulation of plosives in all age groups was not statistically significant (

P

=1.000). The plosives of hearing impaired children aged 3-5 years were not learned (

<

90%)

and the definition of aspirated

plosives was less than that of unaspirated plosives. The difference between the definition of aspirated plosives and unaspirated plosives was statistically significant (

P

=0.010≤0.01). The difference of articulation between hearing impaired children and healthy children at all ages of 3-5 years old was statistically significant

regardless of whether they were aspirated or not. Whether to breathe or not did not affect the acquisition of the initial consonants of the tongue root sound in hearing-impaired children.

Conclusion

2

It is more difficult for hearing-impaired children to acquire aspirated stops with the front of the pronunciation position. During training

it is necessary to strengthen their perception of aspirated stops and improve the clarity of aspirated stops.
