Purpose This tutorial addresses fundamental characteristics of microphones (frequency
response, frequency range, dynamic range, and directionality), which are important for …

While human vocalizations generate acoustical energy at frequencies up to (and beyond) 20
kHz, the energy at frequencies above about 5 kHz has traditionally been neglected in …

Purpose This article integrates published acoustic data on the development of vowel
production. Age specific data on formant frequencies are considered in the light of …

The linear source-filter theory of speech production assumes that vocal fold vibration is
independent of the vocal tract. The justification is that the glottis often behaves as a high …

Speakers of rhotic dialects of North American English show a range of different tongue
configurations for/r/. These variants produce acoustic profiles that are indistinguishable for …

Recent advances in physiological data collection methods have made it possible to test the
accuracy of predictions against speaker-specific vocal tracts and acoustic patterns. Vocal …

The Onset of Language outlines an approach to the development of expressive and
communicative behaviour from early infancy to the onset of single word utterances. Nobuo …

This work reviews the advancements in the non-conventional analysis of speech signals,
particularly from an AM-FM analysis point of view. The benefits of such an analysis, as …

Abstract Magnetic Resonance Imaging (MRI) plays an increasing role in the study of speech.
This article reviews the MRI literature of anatomical imaging, imaging for acoustic modelling …

The vocal tract shape is three-dimensionally complex. For accurate acoustic analysis, a finite-
difference time-domain method was introduced in the present study. By this method, transfer …
