Objective

2

Compare the accuracy of the clarity of the three vowels/a/

/u/

and/i/when combined with labial consonants

analyze the impact of these three vowels on the accuracy of labial consonant pronunciation

and provide scientific basis for the evaluation and training sequence of labial consonants.

Methods

2

173 children with functional articulation disorders were selected and tested by combining the three vowels/a/

/u/

/i/with the three labial consonants/b/

/p/

and/m/to analyze the accuracy and incorrect forms of consonant pronunciation.

Results

2

There is a significant difference in the pronunciation accuracy of double lip consonants/b/

/p/

/m/when combined with different vowels. The order of accuracy is/a/>/u/>/i/

and the order of error rate of consonants is: substitution>omission>distortion. When the incorrect form of a consonant is a substitute

the subsequent vowel remains the original vowel. Consonants combined with/i/are easily replaced by the tip of the tongue midrange

while consonants combined with/u/are replaced by the root of the tongue.

Conclusion

2

When evaluating the pronunciation of children's labial consonants

consideration should be given to combining different vowels. Training should be carried out in the order of combination with opening vowels

closing vowels

and aligning vowels.
