This acoustical and Electroglottography (EGG) study investigates the effect of coda deletion and co-articulatory phasing on vowels and final coda stops, [p t k ?], in Taiwan Min checked tones 3 and 5 syllables. Vowel duration, f0, spectral tilt (H1*-A3*), cepstral peak prominence (CPP) and glottal contact quotient (CQH) were analyzed. Compensatory lengthening, f0 lowering and increasing periodic phonation during the production of vowels after coda deletion were observed. During gradual phasing when codas were produced as energy damping, the vowels were found to be shorter in duration and less periodic in voicing than vowels abruptly phased with coda that were produced as full stop closure. However, spectral tilt H1*-A3* was not affected by either coda deletion or co-articulatory phasing. Therefore, these findings suggest that H1*-A3* may play a salient role in checked tone identification, and, as a result, is unaffected by sound change.

This study explored the effective articulatory and acoustic parameters for distinguishing Taiwan Min falling unchecked tones 53 and 31 and checked tones 5 and 3. Data were collected from Zhangzhou, Quanzhou, and mixed accents in northern, central, and southern Taiwan. Results showed that EGG parameters, Contact Quotients (CQ) and Peak Increase in Contact (PIC) were not effective in distinguishing checked from unchecked tones across speakers. In contrast, f0 contour and Cepstral Peak Prominence (CPP) consistently distinguished checked tones from unchecked tones across speakers. The f0 onset was highest for tone 53, followed in order by tone 3, 5 and 31. The f0 contours of tone 5 were the highest in the later half of the vowels. CPP measures of checked tones were higher than those of unchecked tones in the latter portion of vowels.

This study investigates the effect of L2-English experience on the perception of the English tense-lax high vowel contrast. Experienced L1-Mandarin, inexperienced L1-Mandarin and L1-English listeners identified and discriminated synthetic heed-hid and who'd-hood continua varying in five steps of F I, F2, and F3 variations and seven steps of duration variations. The results show a strong reliance on formant variations by L1-English listeners; reliance on duration variations by the inexperienced L1-Mandarin listeners, and a more dominant reliance on formant cues than on duration cues by the experienced L1-Mandarin listeners.

This paper tried to probe the merging tones and the application of sandhi rule for unchecked tones (/24/[33] and /33/[33]) in Hailu variety of Hakka language. Generally speaking, the sandhi rule was applied in both the younger (under 30) and the older (above 50) groups. Tone merging phenomenon (/24/[24] merging toward /33/[33]) was not found in the older group. Yet, the merging phenomenon was found in the younger group. The sandhi rule for /24/ and /33/ was not observed in most of the young speakers. It is proposed that the /24/ and /33/ tones were undergoing sound change by the younger generation.

This study explores the effects of prosodic boundaries on nasality at intonational phrase, word, and syllable boundaries. The subjects were recorded saying phrases that contained a syllable-final nasal consonant followed by a syllable-initial stop. The timing, duration, and magnitude of the nasal airflows measured were used to determine the extent of nasality across boundaries. Nasal amplitudes were found to vary in a speaker-dependent manner among boundary types. However, the patterns of nasal contours and temporal aspects of the airflow parameters consistently varied with boundary type across all the speakers. In general, the duration of nasal airflow and nasal plateau were the longest at the intonational phrase boundary, followed by word boundary and then syllable boundary. In addition-to the hierarchical influence of boundary strength, there were unique phonetic markings associated with individual boundaries. In particular, two nasal rises interrupted by nasal inhalation occurred only across an intonation phrase boundary. Also, unexpectedly, a word boundary was marked by the longest postboundary vowel, whereas a syllable boundary was marked with the shortest nasal duration. The results here support the hierarchical effect of boundary on both domain-edge strengthening and cross-boundary coarticulation. (c) 2007 Acoustical Society of America.
