“…These data are consistent with studies of the adult voice, which show that fundamental frequency is stable in repeated voice recordings of both sustained vowel and continuous speech. [14][15][16] It reproduces results from Hill et al, 13 which also demonstrated consistency of F 0 across sustained vowel recordings in the pediatric population.…”

Sustained vowel utterance and continuous speech samples provide consistent measures of fundamental frequency. Frequency-based analysis of sustained vowel recordings improves the reliability of perturbation measures. Continuous speech recordings can be obtained in children and demonstrate good to excellent reliability across recordings. This suggests that frequency-based analysis of continuous speech may be more representative of a child's voice and therefore may be of use in the study both of the developmental changes of the pediatric voice as well as the study of vocal changes pretreatment and posttreatment in children with voice disorders.

“…This phenomenon has been demonstrated in both adult and pediatric populations. 13,14,16 In adults, this lack of recording reliability has been attributed to ambient noise, sex differences, hormonal change, time of day, mood, and caffeine intake.…”

“…Approximately 30% of the US population experiences dysphonia at some time in their life, which can be treated with medical, behavioral, and/or surgical interventions . For patients with voice disorders, objective outcome measures (such as acoustic and aerodynamic assessments) are sufficient for distinguishing normal from disordered voices . However, they have demonstrated poor reliability and sensitivity to change .…”

“…Furthermore, subharmonics create 'noise' in the signal that make it impossible to measure features that depend upon a periodic signal [41,42,43]. Although jitter and shimmer have been linked to perceptions of roughness and breathiness, respectively [19], several studies have concluded that they are unreliable indicators of voice quality [41,44,45,46], especially for voices perceived to score highly on measures of Grade, a measure of perceived hoarseness [14]. Furthermore, jitter and shimmer can present as normal in voices that contain subharmonics [47] and are unreliable for diplophonic voices [48,49].…”

Analyses of sustained vowels in Down Syndrome (DS): a case study using spectrograms and perturbation data to investigate voice quality in 4 adults with DS.Objectives. Automatic acoustic measures of voice quality in people with Down Syndrome (DS) do not reliably reflect perceived voice qualities. This study used acoustic data and visual spectral data to investigate the relationship between perceived voice qualities and acoustic measures.Study design. Participants were 4 young adults (2 male, 2 female; mean age 23;8 years) with DS and SevereLearning Disabilities (SLD), at least one of whom had a hearing impairment (HI).Methods. Participants imitated sustained /i/, /u/ and /a/ vowels at pre-determined target pitches within their vocal range. Medial portions of vowels were analysed, using Praat, for Fundamental frequency (f0), HNR, jitter and shimmer. Spectrograms were used to identify the presence and the duration of subharmonics at onset and offset, and mid-vowel. The presence of diplophonia was assessed by auditory evaluation.Results. Perturbation data were highest for /a/ vowels and lowest for /u/ vowels. Intermittent productions of subharmonics were evident in spectrograms, some of which coincided with perceived diplophonia. The incidence, location, duration and intensity of subharmonics differed between the four participants. Conclusions.Although the acoustic data do not clearly indicate atypical phonation, diplophonia and subharmonics reflect nonmodal phonation. The findings suggest that these may contribute to different perceived voice qualities in the study group and that these qualities may result from intermittent involvement of supraglottal structures. Further research is required to confirm the findings in the wider DS population, and to assess the relationships between voice quality, vowel type and physiological measures.
