Aim: To observe psychological stress in the acoustic samples of daily-wage workers belonging to different states in IndiaMethod: The study was based on the observations obtained from prior work on detecting psychoacoustic detectors of psychological stress. Acoustic samples were obtained from interviews conducted by NDTV over a period of March-May 2020. Spectrogram and Fundamental Frequency variations were used to identify psychological stressResults: Stark differences existed in mean fundamental frequency plots by daily-wage workers and non-stressed individuals. Distinct density variations were also observed in the acoustic samples between the two groups.Conclusion: Psychoacoustic detectors of psychological stress were confirmed in the acoustic samples of daily wage-workers, concluding that daily-wage workers are under dire psychological stress and are susceptible to stress-related disorders.Keywords: psychological stress, acoustic variations, daily-wage workers

Fifteen patients, 13 women and 2 men, with a mean age of 72.7 years (56 to 86 years) and a clinical diagnosis of essential voice tremor, were treated with botulinum injections to the thyroarytenoid muscles, and in some cases, to the cricothyroid or thyrohyoid muscles. Evaluations were based on subjective judgments by the patients, and on perceptual and acoustic analysis of voice recordings. Subjective evaluations indicated that the treatment had a beneficial effect in 67% of the patients. Perceptual evaluations showed a significant decrease in voice tremor during connected speech (p < .05). Acoustic analysis showed a nearly significant decrease in the fundamental frequency variations (p = .06) and a significant decrease in fundamental frequency during sustained vowel phonation (p < .01). The results of perceptual evaluation coincided most closely with the subjective judgments. It was concluded that the treatment was successful in 50% to 65% of the patients, depending on the method of evaluation.

Attitudes have been described for different languages, with varying labels or contexts of occurrence for same labels. It renders cross-cultural comparison uncertain. A corpus was designed to bypass these limitations. This paper focuses on USA English produced by L1 and L2 speakers. The best performances in 9 attitudes are used in a forced-choice test, in both audio and visual modalities. Results show that 6 categories group the presented attitudes in coherent sets. The cultural origin affects marginally the categorisation of the expressions. An acoustic analysis of the fundamental frequency and intensity allows to test the predictions of two theoretical propositions – the Frequency code and the Effort code. It concludes to a main coherence of cross-language expressivity, and discusses differences. For negative expressions of imposition, L1 speakers follow the Frequency code – and L1 listeners expect this; L2 speakers use the Effort code in the same situations, leading to confusions in the audio-only modality. Differences for seduction and irony are also discussed.

In this study a mother's instinctive accommodations of vocal fundamental frequency (f0) of infant-directed speech to two different infants was explored. Maternal speech directed to individual 3-mo.-old fraternal twin-infants was subjected to acoustic analysis. Natural samples of infant-directed speech were recorded at home. There were differences in the rate of infants' vocal responses. The mother changed her f0 and patterns of intonation contour when she spoke to each infant. When she spoke to the infant whose vocal response was less frequent than the other infant, she used a higher mean f0 and a rising intonation contour more than when she spoke to the other infant. The result suggested that the mother's speech characteristic is not inflexible and that the mother may use a higher f0 and rising contour as a strategy to elicit an infant's less frequent vocal response.

Nonverbal vocalizations in dementia are important clinically since they generally have been regarded as disruptive behavior that is disturbing. The aim of the present study is to describe the interactional pattern, including the prosodic package, of nonverbal vocalizations in a participant in a late stage of dementia. The acoustic analysis shows that the vocalizations do not differ significantly from the verbal utterances regarding mean fundamental frequency or pitch range. The mean fundamental frequency, F0, of the utterances from Anna was significantly higher than the mean F0 from the other elderly participants. The analysis demonstrates that there is a singing-like type of vocalizations that does not resemble the previously described patterns of nonverbal vocalizations. This pattern of the nonverbal vocalization does not resemble the intonation of Anna’s verbal utterances. The other participants perceive Anna’s vocalizations as potentially meaningful turns. Nonverbal vocalizations in clinical settings should be taken as communicative contributions.

The aim of the study was to find whether a muscle-sparing uvulopalatopharyngoplasty (UPPP) and tonsillectomy cause a measurable change in the voice. The fundamental frequency and the first two formants of five sustained vowels were measured before and nine (six to 15) months following operation. The operation consisted of tonsillectomy and UPPP with preservation of the musculature of the soft palate. All patients received a pre- and post-operative 12-canal polysomnography (level-I sleep study). No patient showed signs of any post-operative velopharyngeal insufficiency. Acoustic analysis showed a significant raising of the fundamental frequency of up to 10 Hz. There was also a lowering of the second formant in two of the five vowels. This was correlated with the volume of the excised tissue. The minimal changes will probably have no significance for those who place no special reliance on their voice, but the possible post-operative changes should be made clear to singers and those relying on their voice for professional reasons.

Abstract Introduction: The voice is heavily influenced by breathing and abdominal muscles. Objective: To verify the immediate effects of cervical stimulation and diaphragmatic release on the respiratory and phonatory function of adult women with no vocal complaints. Method: Relaxation maneuvers and eccentric work of the diaphragm were performed together with articulatory maneuver of the third cervical vertebra. Twenty-four women without vocal complaints, aged between 18 and 35 years were part of the intervention. All volunteers were submitted to an evaluation of respiratory muscle strength, maximum phonation time of the vowel /a/, sound pressure level and acoustic vocal analysis, before and after physiotherapeutic intervention. Statistical analysis consisted of the Student's t-test for independent samples and Spearman's correlation. Significance level was set at 5%. Results: There was a significant increase in the maximum phonation time of the vowel /a/ and in the modal sound pressure level. Regarding the acoustic analysis, there was a reduction in the standard deviation values of the fundamental frequency; in the smoothed pitch disturbance quotient; and in the fundamental frequency and amplitude variations. Conclusion: Cervical stimulation and diaphragmatic release improved vocal quality regarding duration of emission, sound pressure, and stability and noise of the glottic signal.
