Abstract Monitoring small, mobile organisms is crucial for science and conservation, but technically challenging. Migratory birds are prime examples, often undertaking nocturnal movements of thousands kilometres over inaccessible inhospitable geography. Acoustic technology could facilitate widespread monitoring bird migration with minimal human effort. Acoustics complements existing methods by ...

This study examines the acoustic correlates of relative prominence in connected Mandarin speech, particularly those acoustic manifestations that reveal an interaction between stressed and unstressed syllables. The acoustic measurements are primarily concerned with segment duration, intensity, and F0. This study shows that: (1) stressed CV syllables have significantly longer consonant and vowel ...

Introduction: Vocal loudness variation can influence the reability of acoustics analysis. Therefore an intensity acoustic measure such as the Long Term Average Spectrum (LTAS) should be submitted to standard calibration and analysis procedures for realistic results. Purpose: The purpose of this study is to compare the LTAS intensity measures with and without implementation of intensity averagin...

research on stress and stress perception has primarily focused on the acoustic characteristics of stressed versus unstressed syllables, and how listeners make use of acoustic cues to make judgements as regards the occurrence of stress. Most phoneticians agree that the three acoustic dimensions involved in the realisation of stress are duration, fundamental frequency, and intensity. These acoust...
