Acoustic differences between the vowels in filled pauses and ordinary lexical items such as nouns and verbs were examined to know if there was systematic difference of voice-quality. Statistical test of material taken from the Corpus of Spontaneous Japanese showed that, in most cases, there was significant difference of acoustic features like F0, F1, F2, intensity, jitter, shimmer, TL, H1-H2, H...

The paper is devoted to investigation of Bragg diffraction of light by ultrasound propagating in media possessing strong anisotropy of acoustic properties. It is shown that acoustic anisotropy of crystals influences on the process of light and sound interaction. In case of Bragg regime of acousto-optic interaction, intensity of diffracted light and frequency bandwidths of diffraction in the cry...

The laser Doppler flowmeter has been shown to give a response from the cochlea during high intensity acoustic stimulation which is not related to blood flow through the cochlea. The magnitude of this response depends upon the intensity and frequency of stimulation and the location of the probe on the cochlea. Evidence is presented that the response is derived from the vibration of cochlear tiss...

This study investigates acoustic characteristics of Aymara ejectives. Acoustic measurements of the Aymara ejectives were conducted in terms of the durations of the release burst, the vowel, and the intervening gap (VOT), the intensity and spectral centroid of the release burst, and H1-H2 of the initial part of the vowel. Results showed that ejectives vary with place of articulation in the durat...

This article is concerned with the acoustic correlates that characterize stress and accent in Catalan and Spanish. We analyzed four acoustic correlates of stress (syllable duration, vowel quality, overall intensity, and spectral balance) in four conditions, namely, stressed and unstressed syllables in both accented and unaccented environments. This allowed us to examine the relative strength of...

Wojtczak and Viemeister [J. Acoust. Soc. Am. 106, 1917-1924 (1999)] demonstrated a close relationship between intensity difference limens (DLs) and 4-Hz amplitude modulation (AM) detection thresholds in normal-hearing acoustic listeners. The present study demonstrates a similar relationship between intensity DLs and AM detection thresholds in cochlear-implant listeners, for gated stimuli. This ...

This paper presents the first results of the acoustic analysis of 12 pairs of monosyllabic acted vs. spontaneous expressions of satisfaction, irritation and anxiety produced by 4 subjects, discriminated and rated for emotional intensity differences in previous perceptual experiments. Acoustic features in each pair were extracted from the utterances, compared and correlated with perceptual ratin...

This study investigates the acoustic characteristics of /t/ lenition in conversational speech of Brunei Mandarin, a variety of Mandarin Chinese. Based on data from 20 Chinese Bruneians, /t/ lenition was found in the third-person pronoun tā /ta/, which is frequently pronounced as hā [ha]. Perceptual judgments, spectrographic analysis and acoustic measurements were conducted to examine the featur...

This study investigates the acoustic correlates of the distinction between primary and secondary stress in English. It is shown that pitch, intensity, and jitter contribute significantly to that distinction, while durational cues are weak. Left-prominent words are characterized by the acoustic prominence of the primarily stressed syllable (higher pitch, greater intensity, low jitter). In contra...

Humans excel at assessing conspecific emotional valence and intensity, based solely on non-verbal vocal bursts that are also common in other mammals. It is not known, however, whether human listeners rely on similar acoustic cues to assess emotional content in conspecific and heterospecific vocalizations, and which acoustical parameters affect their performance. Here, for the first time, we dir...
