The Impact

ABSTRACT Purpose: There has been growing research on the effects of language on voice characteristics; however, few studies have examined the impact of language on vocal features within bilinguals. This study aimed to compare vocal parameters among bilingual Hebrew/English speaking individuals when speaking in Hebrew versus English. Methods: Forty bilingual participants (17 males and 23 females) between the ages of 23-60 years were asked to spontaneously speak about a neutral topic. Voice samples were digitalized into a tablet for perceptual and acoustic analyses of selected parameters. Results: Results show that there are changes in resonance, glottal attack, fundamental frequency variation and speech rate when adult bilingual speakers talk in Hebrew as compared to English. Conclusion: These findings provide evidence that language plays a role in affecting vocal characteristics of bilingual individuals when they speak different languages.

Summary Background:The presence of decoupling, i.e. the absence of coupling between fundamental frequency variation and intensity contour during phonetic crying, and its extent, reflects the degree of maturation of the central nervous system. Objectives: The aim of this work was to evaluate whether Empirical Mode Decomposition (EMD) is a suitable technique for analyzing infant cries. We hereby wanted to assess the existence and extent of decoupling in term neonates and whether an association between decoupling (derived from EMD) and clinical pain expression could be unveiled. Methods: To assess decoupling in healthy term neonates during procedural pain, 24 newborns were videotaped and crying was recorded during venous blood sampling. Besides acoustic analysis, pain expression was quantified based on the Modified Behavioral Pain Scale (MBPS). Fundamental frequency and the intensity contour of the cry signals were extracted by applying the EMD to the data, and the correlation between the two was studied. Results: Based on data collected in healthy term neonates, correlation coefficients varied between 0.39 and 0.83. The degree of decoupling displayed extended variability between the neonates and also in different cry bouts in a crying sequence within an individual neonate. Conclusion: When considering the individual ratio between the mean correlation of cry bouts during a crying sequence and their standard deviation, there seems to be a positive trend with increasing MBPS value. This might indicate that higher stressed subjects have less consistency in the investigated acoustic cry features, concluding that EMD has potential in the assessment of infant cry analysis.

Voice Fundamental Frequency

The broad objective of the present project was to assess the degree to which esophageal speakers are able to control voice fundamental frequency. Three male esophageal speakers and four age-matched normal speakers were used in a vocal pitch matching task to elicit f 0 levels. Average differences in fundamental frequency between the individual targets and productions were comparable for esophageal and normal talkers, The frequency variation associated with pitch matching by esophageal speakers was 1.5 to 8 times greater than that by normal talkers, The results were interpreted to support (1) the hypothesis that esophageal speakers were less proficient in controlling the steady-state attributes of their voicing source and vocal output; and (2) the view that esophageal speakers exhibit reduced intentional control over voice fundamental frequency.

Vocal communication in social animals plays a crucial role in mate choice, maintaining social structure, and foraging strategy. The Indian grey wolf, among the less studied subspecies, is a social carnivore that lives in groups called packs and has many types of vocal communication. In this study, we characterise harmonic vocalisation types in the Indian wolf using howl survey responses and opportunistic recordings from captive and nine packs (each pack contains 2-9 individuals) of free-ranging Indian wolves. Using principal component analysis, hierarchical clustering, and discriminant function analysis, we found four vocal types using 270 recorded vocalisations (Average Silhouette width Si = 0.598) which include howls and howl-bark (N=238), whimper (N=2), social squeak (N=28), and whine (N=2). Although having a smaller body size, Indian wolf howls have an average mean fundamental frequency of 0.422KHz (±0.126), which is similar to other Holarctic clade subspecies. The whimper showed the highest frequency modulation (37.296±4.601 KHz) and the highest mean fundamental frequency (1.708±0.524 KHz) compared to other call types. Less information is available on the third vocalisation type, i.e. ‘Social squeak’ or ‘talking’ (Mean fundamental frequency =0.461±0.083 KHz), which is highly variable (coefficient of frequency variation = 18.778±3.587 KHz). Our study’s characterisation of the Indian wolf’s harmonic vocal repertoire provides a first step in understanding the function and contextual use of vocalisations in this social mammal.
