Preaspiration in phonological stop contrasts : an instrumental phonetic study
This study is an experimental phonetic investigation of phonological voicing oppositions - specifically, those involving preaspiration as found in Icelandic, Scottish Gaelic, and Irish. Three main aspects of these oppositions are dealt with. - The first involves the production 8f these contrasts. Productions by native speakers of the three languages were monitored using techniques including electroaerometry and photoelectric glottography. Specific attention is directed to the durational correlates of the opposition, and how these vary across languages and for different phonetic environments, including stress variation. The differences and similarities between contrasts which involve preaspiration and those which involve postaspiration are discussed in some detail. In considering production aspects of these oppositions, interest focusses also on the laryngeal mechanisms which control voicelessness and aspiration (pre- and post-). Glottographic data presented suggests that the nature and the amplitude of glottal gesture for a voiceless or aspirated stop is very precisely tailored to the prevailing aerodynamic conditions. The second aspect considered is that of the historical development of these contrasts. Past
