closure gesture. As the escape channel is being closed, air velocity increases and friction is unavoidably created at the place of the closure. However, the duration of this friction is sometimes far greater that can be justified by seeing it as a mere by-product of the closure gesture. Third, a fricative with a place of articulation corresponding roughly with the place of maximal dorsal constriction in the vowel is produced. If the vowel is front and close, the friction will be palatal. If the vowel is open and central or back (e.g., [] or []) one often observes (both auditorily and in spectral analysis) uvular friction, sometimes combined with a pharyngeal stricture. If such a stricture is made, it tends to be maintained throughout much of the production of the preaspiration, and appears to be a way of enhancing the otherwise weak glottal friction. To designate any of these types as a typical or representative preaspiration production of preaspiration in Tórshavn Faroese would be misleading. The different sources of variation interact to produce various results, many of which are illustrated below. s x h e Figure 4–46. Subj.

BJ: […er] mitt [úti…] ‘…is in the middle…’ A common pronunciation for a sequence of an open vowel and a dental fortis stop involves a vocalic interval, an interval of breathiness or aspiration, an interval of friction originating at the stop’s place of articulation, and finally a stop closure. Such a sequence is depicted in Figure 4–46. As glottal abduction is initiated during the production of the vowel ([]), the amplitude in the upper reaches of the vowel spectrum dimin-

ishes sharply. This point is referred to here as modal voice offset (see section 4.1.2). The glottal aperture increases rapidly in this case, and the amplitude weakening spreads to the lower frequencies. Full voice offset follows, but sometimes with a considerable delay. In the present example, full voice offset occurs approximately 25 ms after modal voice offset. Gradually, as the tongue blade forms the dental closure, the fricative noise increases. The resulting []-like sound is approximately 15 ms long in the example in Figure 4–46. After close vowels, especially close front vowels, the oral friction noise is much more obtrusive, and often suppresses the glottal friction noise altogether. In Figure 4–47, a sequence of a close front vowel and a dental stop is produced. Here, modal voice offset occurs more than 50 ms before voice offset and thus the lag between modal voice offset and voice offset is much greater than in the previous example. At the very onset of the preaspiration, the friction noise can be attributed to the narrow escape channel of the vocalic stricture. Then, the friction noise gradually increases in intensity and in frequency range, as the tongue blade moves towards a prepalatal laminal closure. In this case, it is difficult to attribute the stricture for the friction to either vowel constriction or stop closure separately. The articulators involved in the production of the vowel and the stop closure, the tongue dorsum and the tongue blade, cannot act independently of one another. The combination of a close front vowel and a dental stop produces a palato-alveolar constriction. The resulting friction is therefore neither clearly palatal nor dental, but can rather be characterised as coming from a stricture that extends from the palatal to the dental region. In a sequence of a back vowel and a velar stop, the tongue dorsum is responsible for both the vocalic constriction and the stop closure constriction. As a result, the place of articulation tends to be further back than for a velar stop that follows a central or a front vowel, and the vowel tends to be slightly raised. When such stops are preaspirated, as in the example in Figure 4–48, the glottal friction is often modified by a uvular or pharyngeal constriction. Since the dorsal constriction in such sequences contains both the vocalic and consonantal configurations, the – 163 –
