OBJECTIVETo investigate the consonant pronunciation characteristics of older unoperated cleft palate patients.

METHODSOne hundred unoperated cleft palate patients (more than 8 years old) were included. Subjective speech assessment was delivered to each patient. The incidence and distribution of varies consonant misarticulation errors consisting of manners and places of articulation were summarized.

RESULTSConsonant misarticulation existed among 86% of all cases. Compensatory misarticulation was observed in 66% patients, while 14% patients demonstrated completely normal articulation. The articulation manners of the highest correction rate, in succession, were nasals, lateral, fricatives, stops, and affricates. The error type of stops and affricates mainly consisted of compensation and omission. The articulation places of the highest correction rate, in succession, were bilabial, alveolar, linguadental, and velar.

CONCLUSIONCompensatory, omission, and substitution, which happen in all the stops, fricatives and affricates, are the top three misarticulation. The misarticulation incidence of unaspirated sound is higher than that of aspirated. Compensatory errors a the most common ones in aspirated sounds, while omission and weak pressure are more frequent in unaspirated sounds. Weak pressure is mainly observed in unaspirated consonants. As the articulation spot move backward, the compensation of fricatives and stops deteriorate, the omission of affricates increase.

OBJECTIVETo explore the phonological characteristics and rehabilitation training of abnormal velar in patients with functional articulation disorders (FAD).

METHODSEighty-seven patients with FAD were observed of the phonological characteristics of velar. Seventy-two patients with abnormal velar accepted speech training. The correlation and simple linear regression analysis were carried out on abnormal velar articulation and age.

RESULTSThe articulation disorder of /g/ mainly showed replacement by /d/, /b/ or omission. /k/ mainly showed replacement by /d/, /t/, /g/, /p/, /b/. /h/ mainly showed replacement by /g/, /f/, /p/, /b/ or omission. The common erroneous articulation forms of /g/, /k/, /h/ were fronting of tongue and replacement by bilabial consonants. When velar combined with vowels contained /a/ and /e/, the main error was fronting of tongue. When velar combined with vowels contained /u/, the errors trended to be replacement by bilabial consonants. After 3 to 10 times of speech training, the number of erroneous words decreased to (6.24±2.61) from (40.28±6.08) before the speech training was established, the difference was statistically significant (Z=-7.379, P=0.000). The number of erroneous words was negatively correlated with age (r=-0.691, P=0.000). The result of simple linear regression analysis showed that the determination coefficient was 0.472.

CONCLUSIONSThe articulation disorder of velar mainly shows replacement, varies with the vowels. The targeted rehabilitation training hereby established is significantly effective. Age plays an important role in the outcome of velar.

BACKGROUND AND OBJECTIVES: Many research papers showed that the most common articulation disorder in tongue-tie children was the error of alveolar sound. We performed speech therapy on alveolar sound after lingual frenulotomy to prove that the speech therapy after lingual frenulotomy improves the articulation of alveolar sound and that this effect is maintained. MATERIALS AND METHODS: We collected 28 children who never had speech therapy but could afford to have the speech therapy. The accuracy rate of consonant sound was calculated using a picture consonant test 2 weeks following the lingual frenulotomy. The speech therapy, called the phonetic placement and paired-stimulus technique, was performed 18 times for 3 months. This therapy decreased incidence rate of error. RESULTS: The incidence rate of alveolar sound error, which was calculated before speech therapy, was about 65%. And the incidence rate of alveolar sound error after speech therapy was 5-10%, which proved the effect of speech therapy. We divided alveolar sounds into target sounds and non-target sounds. And we performed speech therapy only on target sounds so the appearance rate of alveolar sound error decreased and the incidence rate of non-target sounds also decreased. We performed speech therapy after 2 weeks and the effect was maintained. CONCLUSION: The incidence rate of alveolar sound error decreased by using speech therapy and the effect was maintained. So the speech therapy must be performed after lingual frenulotomy.

OBJECTIVE: To analyze speech and linguistic features in children with articulation disorder characterized by consonant and vowel phonological errors. METHODS: Between February 2007 and June 2015, 117 children who showed articulation disorder were selected for the study. Based on comprehensive speech and language assessments, the subjects were classified into articulation dysfunction (AD), or AD overlapping with language delay. Detailed information of articulation, including percentage of consonants correct (PCC) and normal percentage of variable consonants derived from the Assessment of Phonology and Articulation for Children test, were compared between the two groups. RESULTS: Totally, 55 children were diagnosed as AD and 62 as AD with language delay. Mean PCC was not significantly different between the two groups. In both groups, the acquisition order of consonants followed the universal developmental sequence. However, differences were observed in the nasal & plosive consonants abnormality between the two groups. When adjusted to their delayed language level in AD with language delay group, 53% of children had appropriate articulation function for their expressive language level. CONCLUSION: Speech and linguistic characteristics in children with articulation disorder were variable. Therefore, comprehensive assessment is required in children with inaccurate pronunciation, and a proper treatment plan based on the results of assessment should be followed.

BACKGROUND AND OBJECTIVES: To determine the extent of speech articulation disorder in ankyloglossia patients and to determine whether picture consonant articulation test has potential as a screening test to predict the outcome of surgery. SUBJECTS AND METHOD: A total of 35 patients (25 boys and 10 girls with mean age of 3.69+/-1.18 years) with ankyloglossia who underwent frenotomy and recovered completely without complications were enrolled in this study. We examined the correlation between the subjective satisfaction of parents and the results of picture consonant articulation test. RESULTS: In the picture consonant articulation test, 20 patients (20/35, 57.14%) needed postoperative speech therapy. When the resutls of preoperative picture consonant articulation test and postoperative parents' subjective satisfaction were compared, "normal" had a satisfaction score of 4.53+/-0.74 points, "consider" had 3.89+/-1.05 points, and "demand" had 3.27+/-1.45 points. When a postoperative speech therapy was required, parents' satisfaction decreased (correlation coefficient r=-0.456). CONCLUSION: The preoperative picture consonant test in our study showed potential as a screening test for predicting the outcome of surgery for ankyloglossia patients.

OBJECTIVE: To evaluate correlations between values of articulation tests and language tests for children with articulation disorder in Korea. METHODS: Data of outpatients with chief complaint of an articulation problem were retrospectively collected. Patients who underwent Urimal Test of Articulation and Phonation (U-TAP) with Assessment of Phonology and Articulation for Children (APAC), Preschool Receptive-Expressive Language Scale (PRES), or Receptive and Expressive Vocabulary Test (REVT) simultaneously were identified. Patients whose word-level percentages of correct consonants in U-TAP (UTAP_wC) were more than 2 standard deviations below the mean as diagnostic criteria for articulation disorder were selected. Those whose receptive language age (P_RLA), expressive language age (P_ELA), or combined language age (P_CLA) in PRES was delayed more than 24 months compared to their chronological age in months as diagnostic criteria for language disorder were excluded. RESULTS: Thirty-three children aged 3–6 years were enrolled retrospectively. PRES and U-TAP showed significant correlations for most of value relationships. PRES and APAC showed significant correlations for all value relationships except for receptive language age. All values of REVT were significantly correlated with all values from U-TAP, but not with any value from APAC. Articulation tests U-TAP and APAC showed significant correlations between percentages of correct consonants. Language tests PRES and REVT showed significant correlations for all value relationships. CONCLUSION: This study suggests that articulation abilities and language abilities might be correlated in children with articulation disorder.

OBJECTIVETo explore the clinical characteristic of functional articulation disorders in children and provide more evidence for differential diagnosis and speech therapy.

METHODS172 children with functional articulation disorders were grouped by age. Children aged 4-5 years were assigned to one group, and those aged 6-10 years were to another group. Their phonological samples were collected and analyzed.

RESULTSIn the two groups, substitution and omission (deletion) were the mainly articulation errors in these children, dental consonants were the main wrong sounds, and bilabial and labio-dental were rarely wrong. In age 4-5 group, sequence according to the error frequency from the highest to lowest was dental, velar, lingual, apical, bilabial, and labio-dental. In age 6-10 group, the sequence was dental, lingual, apical, velar, bilabial, labio-dental. Lateral misarticulation and palatalized misarticulation occurred more often in age 6-10 group than age 4-5 group and were only found in lingual and dental consonants in two groups.

CONCLUSIONMisarticulation of functional articulation disorders mainly occurs in dental and rarely in bilabial and labio-dental. Substitution and omission are the most often occurred errors. Lateral misarticulation and palatalized misarticulation occur mainly in lingual and dental consonants.

articulation disorders after surgical operation. Speech evaluations of VPI are recently used to non-invasive aerodynamic and acoustic methods which diagnose the resonance and articulation disorders of cleft palate speakers. However, many researchers are apt to find the speech characteristics of Cleft Palate using individual acoustic, aerodynamic and physiological methods. The aim of this study was to find the correlation of the hypernasality between acoustic and aerodynamic parameters. Ten adult control group and three cleft palate participated to this study. Test words were composed to meaningless polysyllabic words contained stop, affricated and fricative sounds. Nasometer II, CSL and Aerophone II were used to measure Nasalance, vowel formants(F1, F2 and F3) aad bandwidths(BW1, BW2 and BW3), airflow, volume and air pressure. Correlation of hypernasality between acoustic and aerodynamic are treated statistically by SPSS porogram. The results are as follows: (1) Hypernasal correlations with acoustic are statistically significant formant 1, vowel formant 2 and Bandwidth 1 with r=.903 (<0.01), r=.721(<0.05) and r=.801(<0.05), respectively. (2) Hypernasality correlation with aerodynamic are sttisticalyy significant airflow and volum with r=.870(<0.01) and r=.000(<0.01), respectively.]]>
