Introducing Phonetic Science

Stance and affect in conversation: On the interplay of sequential and phonetic resources

“…Within intonation studies and descriptions of voice quality there is a continuing tradition of employing lay attitudinal categories (e.g. ÔchallengingÕ, ÔsurprisedÕ, ÔsympatheticÕ, ÔsadÕ, ÔinvolvedÕ, ÔuncertainÕ, ÔpassionateÕ, ÔexasperatedÕ) in trying to account for the distribution and meaning of intonation contours (Ashby and Maidment 2005;Bolinger 1989;Cruttenden 1997;Hirschberg 2002;Ladd 1996;Sweet 1911;but cf. Selting 1996 for a rigorous analysis of so-called Ôastonished repairsÕ in German which takes into account both prosodic and interactional details).…”

Language Science and Language Technology in Africa: Festschrift for Justus C. Roux

“…There are also specialised instruments for measuring airflow and air pressure variations in aerodynamic studies. Detailed descriptions of techniques and technical devices of the phonetics laboratory, for speech analysis and for the study of the anatomy and physiology of speech production are found in, among others, Ashby and Maidment (2005), Johnson (1997) and Ladefoged (2003). Language researchers on Bantu languages in Southern Africa cannot therefore continue to rely solely on subjective methods of direct observation and sensory perception when tools are actually available to conduct scientific investigations of the sound systems of these languages.…”

The speech signal segmentation algorithm using pitch synchronous analysis

“…It should be noted that the base pitch frequency is characteristic of any speaker and is determined by individualities of the larynx structure. The average for a male voice ranges from 80 to 210 Hz, for female -from 150 to 320 Hz [10]. Therefore, frequencies located above or below this range are considered to be redundant for the task of PF isolating.…”
