Transcranial direct current stimulation (tDCS) can be used to temporarily and reversibly modulate brain functions and is an increasingly utilized tool to investigate the relationships between brain and behavior. This study aimed to identify the brain area where tDCS has the greatest effect on vocal quality, vocal range, neuromotor functioning of the larynx, and self-reported vocal effort in vocally healthy individuals. Sixteen adults, non-singers, with a mean age of 22.5 (±1.9) years and no vocal symptoms or brain dysfunction, participated in this double-blinded randomized crossover clinical trial. The participants underwent four anodal tDCS session (20 minutes;2 mA) in targeting different areas—cerebellum, primary motor cortex (M1), primary somatosensory cortex (S1), and dorsolateral prefrontal cortex (DLPFC)—with a 7-day washout period between sessions. Volunteers were evaluated for vocal performance before and after each tDCS session. Voice recordings were taken to assess the following vocal parameters: vocal range profile (VRP) at weak and strong intensities;vocal quality (jitter, shimmer, irregularity, glottal-to-noise excitation ratio, and dysphonia acoustic index) at weak, habitual, and strong intensities;laryngeal diadochokinesis, and self-reported vocal effort using the adapted Borg CR10 scale. M1 stimulation enhanced the VRP by increasing maximum intensity and improving vocal quality, particularly at habitual and strong intensities. Similarly, S1 stimulation improved vocal quality at strong intensities but reduced the VRP by lowering the maximum fundamental frequency. Cerebellum stimulation enhanced neuromuscular control and coordination of the larynx without affecting vocal quality. Additionally, self-reported vocal effort decreased across all stimulated areas following tDCS. Our findings indicate that tDCS applied to different brain areas produces varying effects on vocal parameters. © 2024 The Voice Foundation

Perception of place-of-articulation contrasts of English word-final consonants in connected speech by Japanese and Korean second language learners

An extension of a previous study examining Japanese listeners’ perception of place contrasts of English word-final stops in connected speech (Ito, 2010) was carried out by administering the same experiment to Korean listeners. Stimuli embedded in a carrier sentence and produced in fast casual speech were presented in a three-alternative forced choice identification test, adopting minimal triplets (e.g., sip-sit-sick, bib-bid-big, Kim-kin-king) followed by an adverb starting with /p/, /t/, or /k/. Data for 24 Korean listeners were compared with the previous data for 24 Japanese and 24 American English (AE) listeners. Whereas Japanese listeners had exhibited severe difficulty in perceiving place contrasts of nasal and voiceless stops, Korean listeners were expected to have much less perceptual difficulty on those contrasts because of the different L1 phonological rules of final stops. Results revealed that Koreans’ response accuracy was much higher than that of Japanese on voiceless stops (Korean 82%, Japanese 67%, AE 90%) and nasal stops (Korean 96%, Japanese 66%, AE 98%), conforming to the predictions. The contrasting performance between Korean and Japanese listeners on nasal stops was especially remarkable, strongly supporting the notion that Japanese listeners’ difficulty in perceiving place contrasts of word-final nasals is due to their L1phonological rules.

UNLABELLED:Few studies have demonstrated the pathologic reactions yielded by smoke inhalation on the airway in rats. AIM:The aim of this study was to analyze the possible histopathological effects produced by chronic cigarette smoke inhalation on the vocal folds of rats. STUDY DESIGN:Experimental. MATERIAL AND METHOD:36 male rats (Rattus norvergicus Wistar strain), aged 60 days, were kept in cages and exposed to inhalation of the smoke produced by 10 cigarettes lit 3 times a day, 7 days a week, for periods of 25, 50 and 75 days, and their respective controls. Thereafter the animals were killed and their larynxes were dissected and submitted to histological processing for achievement of histological sections, which were stained with Hematoxylin and Eosin and analyzed by light microscopy. RESULTS:The rats exposed to smoke displayed smaller (p< 0,05) body mass than the control group. There was hyperplasia and squamous metaplasia in the free edge of the vocal fold and squamous hyperplasia on the middle portion of the vocal fold in all 3 study periods. Moreover, the 50-day group revealed keratinizing metaplasia in this area. Morphological alterations in other areas of the larynx and inflammatory reaction of the lamina propria were also not observed. CONCLUSION:It was concluded that the passive inhalation of cigarette smoke yields important morphological changes in the vocal fold epithelium, which may progress to neoplasia.

Perception of bistable stimuli is influenced by prior context. In some cases, the interpretation matches with how the preceding stimulus was perceived;in others, it tends to be the opposite of the previous stimulus percept. We measured high-density electroencephalography (EEG) while participants were presented with a sequence of vowels that varied in formant transition, promoting the perception of one or two auditory streams followed by an ambiguous bistable sequence. For the bistable sequence, participants were more likely to report hearing the opposite percept of the one heard immediately before. This auditory contrast effect coincided with changes in alpha power localized in the left angular gyrus and left sensorimotor and right sensorimotor/supramarginal areas. The latter correlated with participants’ perception. These results suggest that the contrast effect for a bistable sequence of vowels may be related to neural adaptation in posterior auditory areas, which influences participants’ perceptual construal level of ambiguous stimuli. © 2023 The Author(s)

ObjectiveTo examine the association between individual and cumulative leisure noise exposure in addition to acceptable yearly exposure (AYE) and hearing outcomes among a nationally representative sample of ***, distortion-product otoacoustic emissions (DPOAEs) and in-person questionnaires were used to evaluate hearing and leisure noise exposure across age, sex, and household income/education level. High-risk cumulative leisure noise exposure was defined as 85 dBA or greater for 40 h or more per week, with AYE calculations also based on this occupational *** sampleA randomised sample of 10,460 respondents, aged 6–79, completed questionnaires and hearing evaluations between 2012 and *** 50–79 year olds, high-risk cumulative leisure noise was associated with increased odds of a notch while high exposure to farming/construction equipment noise was associated with hearing loss, notches and absent DPOAEs. No associations with hearing loss were found however, non-significant tendencies observed included higher mean hearing thresholds, notches and hearing loss *** outreach and monitoring of hearing among young and middle-aged populations exposed to hazardous leisure noise would be beneficial.

Acoustic correlates of stop consonant voicing in English and Spanish

引用

The Journal of the Acoustical Society of America 2012年第3_SUPPLEMENT期132卷 1937-1937页

作者： Olga Dmitrieva Amanda A. Shultz Fernando Llanos Alexander L.

In English, fundamental frequency at the onset of voicing (onset f0) co-varies with the Voice Onset Time (VOT) of initial stops and provides an additional perceptual cue to the phonetic feature of voicing, especially when VOT is ambiguous. However, aerodynamic and physiological explanations of the onset f0/VOT relationship suggest that onset f0 should correlate with voicing only in languages such as English that contrast short lag (voiceless unaspirated) with long lag (voiceless aspirated) consonants, and not in languages such as Spanish that contrast prevoiced with short lag stops. Previous perceptual research supports this prediction: Spanish speakers with little English experience do not incorporate onset f0 in making voicing decisions, suggesting lack of a correlation in their ambient language. In contrast, Spanish speakers with extensive experience with English show an English-like pattern of onset f0 use, suggesting that exposure to the English pattern of covariation has influenced their perceptual weighting of these two cues. The present study compares the distribution and correspondence between VOT and onset f0 in syllable-initial bilabial stops ([b] - [p]) in Spanish and English. Implications for the typology of voicing contrasts and perceptual strategies for sound categorization in non-native language environments are discussed.
