Summary: This article presents a detailed analysis of nine Konkani vowels, including an acoustic-phonetic analysis, and proposes a vowel chart for Konkani based on experimental results. The study also observes a partial loss of Konkani vowel in the regular speech of native speakers.

Summary: The study evaluated the effect of ageing on vowel articulation and provided normative acoustic data for all Czech monophthongs. Age-related changes in pitch were sex-dependent, while alterations in F-2/a/, F-2/u/, VSA, and vowel duration seemed to be sex-independent. The findings suggested small or anti-centralization changes in vowel articulation across several decades of adult life.

Summary: This study aimed to explore the effects of speakers' intended confidence on both prosodic and formant features of vowels in Wuxi dialect. The results showed that speakers raised both F1 and F2 in the confident level, and F1 could distinguish between confident and unconfident expressions. The study also found that speakers modulated mean f0, mean intensity, and intensity range to a greater extent in the unconfident level compared to the confident level. Additionally, the modulation of f0 and intensity range was more prominent in the contour tone than in the flat tone.

Summary: Speech impairment is a common problem after maxillary tumor resection, and maxillofacial prosthodontists play a vital role in restoring speech function. This study determined that Praat and CSL have similar results for speech analysis, and the default settings in Praat can be used for formant analysis in maxillectomy patients.

Summary: Music, as a human communicative art, may have evolved from capacities related to cooperation and competition. A study found that human chorusing involves both cooperative behavior to attract potential mates and competitive behavior to attract actual mates. In a renowned boys choir, older boys with deeper voices increased the acoustic prominence of their voices by enhancing high-frequency energy when there were girls in the audience. Female listeners showed a preference for this subtle vocal modulation and were more sensitive to it compared to male listeners.

Summary: GTSL features, inspired by nonlinear phenomena in human phonation and incorporating auditory characteristics, quantify turbulent noise through nonlinear compression. In pathological voice detection, GTSL features outperform traditional features with higher accuracy with traditional machine learning algorithms.

Summary: This study proposes three different neural network architectures for multi-class classification of various voice pathologies, achieving high accuracies. The MLP and STFT models performed well in terms of accuracy, while the MFCC model showed improved accuracy on the Reflux Laryngitis class. The study also identifies crucial features and highlights the challenges in voice abnormality classification.

Summary: This study presents an acoustic analysis of Oromo vowels of the northern dialect. The study collected data from 19 speakers and analyzed measures such as duration, fundamental frequency, and formant frequencies. The results show that gender and vowel quality have significant effects on the acoustic measures, with females producing vowels with greater duration and formant frequencies. Support Vector Machine was used for vowel classification, showing time-varying frequency not being advantageous for separating genders but being effective for dialect classification.

Summary: This study aims to provide a fully-automated approach for children's age prediction based on voice acoustics. Using sustained phonation of vowels as features, accurate age estimation for children can be achieved, with higher accuracy for boys. However, there may be some errors in predicting the age of early childhood.

Summary: Common measurement tools in the perceptual evaluation of voice quality often yield ordinal data, making it difficult to establish mathematical relationships. Develop standard measurement scales for voice quality dimensions, aiming to create scales for breathiness and roughness qualities. Establish relationship between perceived voice quality and physical units, supporting quantitative comparisons of perceptual judgments.

Summary: This paper explores the temporally dynamic patterns of vowel nasalization in two speakers of Arabana. By using gradient tree boosting algorithms, a speaker-specific mapping between acoustics and vowel nasality is statistically learned to measure the dynamic nasality. The three primary findings are: (1) NVN contexts consistently exhibit nasalization, suggesting resistance to diachronic change; (2) anticipatory nasalization is comparable to carryover nasalization, contrary to previous claims; and (3) vowel nasalization in word-initial contexts is relatively high, indicating the ongoing sound change involves loss of oral constriction but not complete loss of the velum gesture.

Summary: Diagnosing Parkinson's Disease (PD) and monitoring symptom progression is crucial for timely treatment. Recent studies have shown the potential of using audio recordings to detect signs of PD. However, disparities between studies may be due to differences in methodology and data preparation. This paper evaluates the influence of methodological issues in automatic PD detection, provides recommendations to address these issues, and emphasizes the importance of avoiding overoptimistic or misleading results.
