Abstract:
One way of investigating how tone languages and dialects differ with
respect to their tonal phonetics is to use bilingual or bidialectal
speakers. In this paper, the tones of a speaker who has native command
of not just two, but three varieties of tone language are investigated
acoustically and perceptually: Standard Thai, with 5 tones; Lao, with
7; and Nyo, with 4. This makes a maximum of 16 possible Linguistic-tonetically
different tones. Mean fundamental frequency and duration values are
presented for the allotones of the Lao, Standard Thai and Nyo tonemes
on syllables with unstopped Rhymes. A perceptual experiment is described
to determine how many of the 16 allotones are identifiable by Nyo tridialectal
listeners. This approach enables us in a sense to see through the ears
of both native speaker and native listener. The acoustic and perceptual
data are used to demonstrate the existence of 10 linguistic-tonetically
distinct tones. It is speculated that this might represent an upper
limit for a multidialectal speaker.

Abstract:
This paper examines the behaviour of complex tones in tone sandhi,
using data from a seven-tone Southern Thai dialect. Measurements of
mean fundamental frequency and duration are presented for unstopped
and stopped citation allotones and also for unstopped tones in combination.
Tonological implications are drawn.

Abstract:
The tonemes of the Waromung Mongsen dialect of Ao Naga, a Tibeto-Burman
of northeast India, are described with respect to their auditory and
acoustic features. Even though rather small FO differences are found
to separate each contrasting toneme, the results of a perception test
nevertheless demonstrate that these small differences are perceptually
salient to a native speaker and are readily identifiable.

Abstract:
This paper examines one aspect of the phonetic mapping of tone onto
segmental material. It asks whether prevocalic semivowels ([j- &
w-]) can be said to constitute part of the material over which tonal
F0 is distributed. The distribution of acoustical correlates of tone
(F0, duration) is determined on syllables differing with respect to
semivowels in the segmental structure in three of the contrasting contour
tones (falling, convex and low rising) from the Chinese Wu dialect
of Zhenhai. Four different syllable-structures are examined. It is
concluded that (1) syllable-initial semivowels are not tonally relevant,
and (2) semivowels behave differentially with respect to phonetic mapping
depending on whether they are preceded by a syllable-initial consonant.
Implications of the finding are explored for the phonological integration
of semivowels into metrical syllable structure. The relevance of the
finding is also pointed out for the measurement of tone (and intonation)
acoustics in running speech.
