“…The current study revealed that there is overall significant difference between the RCLP and TDC groups with respect to fundamental frequency, intensity and perturbation parameters. Similar findings have been reported in previous studies [17,18]. Children with RCLP in the current study had persistent velopharyngeal dysfunction.…”

“…The study revealed a direct correlation between jitter and perceived nasality and on the other hand shimmer was found to be directly correlated with perceived hoarseness [16]. Few other studies investigating the acoustic parameters of voice have reported that the voice of children with CLP is characterised by the presence of frequency instability, high intensity, abnormal formant distribution and abnormal spectrograms [16][17][18].…”

There is an increase of children with cleft of lip and palate in India. However the number of studies investigating the voice characteristics of children with CLP in any of the Indian languages is sparse. Thus the current study is aimed at investigating the voice characteristics viz., fundamental frequency, intensity, jitter and shimmer in 3 to 5 year old native Kannada speaking children with repaired cleft of lip and palate (RCLP). Twenty children with RCLP were considered for the study that were divided into 3 to 4 year old and 4 to 5 year old groups. Twenty age matched typically developing children were also considered for the study. Phonation of vowel /a/ was recorded for each child and analysed using Praat (5.4.14) software. Appropriate statistical analysis was done to compare the results between groups and across ages. The results revealed that only fundamental frequency was statistically different between the groups however age effect was not seen for the same. The remaining parameters viz., intensity, jitter percentage and shimmer percentage were not found to be statistically significant between groups and across ages as well. The reasons for the same are discussed.

“…The evaluation of cleft palate speech can be divided into subjective evaluation and objective evaluation. 9 Subjective evaluation has been considered as the "gold standard" of clinical speech evaluation in the past, and it is very important and necessary to conduct subjective evaluation of speech for the patients with cleft palate. 10,11 However, subjective evaluation result is more accurate only when the listener has certain clinical experience, some objective examination and evaluation is also necessary.…”

To explore the speech outcomes of adult patients through subjective perception evaluation and objective acoustic analysis, and to compare the differences in pronunciation characteristics between speakers with adult patients with unrepaired cleft palate and their non-cleft peers.Participants and Intervention: Subjective evaluation indicators included speech intelligibility, nasality, and consonant missing rate, whereas objective acoustic parameters included normalized vowel formants, voice onset time, and the analysis of threedimensional spectrogram and spectrum, were carried out on speech samples produced by 2 groups of speakers: (a) speakers with unrepaired cleft palate (n = 65, mean age = 25.1 years) and (b) typical speakers (n = 30, mean age = 23.7 years). Results: Compared with typical speakers, individuals with unrepaired cleft palate exhibited a lower speech intelligibility with higher nasality and consonant missing rate, the missing rate is highest for the 6 consonants syllables The acoustic parameters are mainly manifested as differences in vowel formants and voice onset time. Conclusions: The results revealed important acoustical differences between adult patients with unrepaired cleft palate and typical speakers. The trend of spectral deviation may have contributed to the difficulty in producing pressure vowels and aspirated consonants in individuals with speech disorders related to cleft palate.
