Participants completed four tasks in both languages: engaging in free narration, describing a picture story, giving directions, and reading a narrative passage. For the last three tasks, the difficulty levels were varied. Measurements included jitter, shimmer, harmonics-to-noise ratio (HNR), cepstral peak prominence (CPP), the proportion of creak, pitch level, and pitch span. Changes in voice characteristics were examined both in terms of the participants' age and their language dominance. For the latter, we calculated a dominance score derived from age of acquisition, frequency of use, and self-perceived linguistic competence in the two languages.</div></div><div><h3>Results</h3><div>Younger speakers showed a higher dominance of HG over LG, which decreased with age. Younger and more HG-dominant speakers exhibited lower jitter and shimmer, along with a higher HNR and a lower creak proportion in LG compared to HG. CPP and pitch level were higher in LG but showed little variation with age or language dominance. No clear effects on pitch span were observed. Overall, age was a slightly more reliable predictor than language dominance. Acoustic differences in voice quality were about equally detectable across the different speech tasks while varying difficulty levels had minimal impact.</div></div><div><h3>Conclusions</h3><div>The variation in vocal fold vibratory patterns suggests that younger and more HG-dominant speakers experienced greater cognitive load when speaking LG.

First, individual interviews were conducted with dysphonic and non-dysphonic children and their parents, teachers, and speech pathologists. Second, the responses collected from the interviews were arranged into a comprehensive list of 175 items. Third, this list was reduced to a preliminary 21-item version of the questionnaire, which was tested as a pilot with 254 children. Fourth, a further reduction to 18 items was performed to construct the final version of the CVQ. The questionnaire was then administered to 342 children (73 dysphonic, 269 non-dysphonic) aged 6–18. Simultaneously, the parents of these children completed the </span>pediatric voice handicap index (pVHI).
