In this paper we document a previously unknown allophony pattern of the posterior affricate in Mee (Trans New Guinea; Indonesia). The affricate is realized as a laterally released velar stop [gʟ] before front vowels and with uvular closure followed by a fricative release [ɢʁ] before back vowels. Our description is confirmed in an acoustic study that shows differences in the second formant of the preceding vowel and the periodicity of the release for the two allophones. The interaction between the consonant's place and the following vowel challenges previous claims about the absence of major place (or C-Place) assimilation between vowels and consonants. Our OT-Analysis captures this process by postulating two agreement constraints: one requiring agreement between the release and the vowel and another -- between the closure and the release. Although there is no constraint promoting agreement between C closure place and V quality, we show that this effect can be derived from two local constraints.

Velar lateral sounds are rare and their acoustics and contextual effects are understudied. Positional variants of velar laterals are also rarely reported. This paper documents a previously unknown allophony pattern of the velar lateral in Mee (Trans New Guinea; Indonesia), based on an elicitation study with two speakers and a controlled set of recordings from one of the speakers. Our main dataset included carrier phrase recordings of Mee words with the velar lateral, representing the diverse set of contexts where the velar lateral occurs. Our acoustic findings suggest that the Mee velar lateral is realized as a laterally released velar stop [ɡᶫ] before front vowels, and with uvular closure followed by a fricative release [ɢʁ] before back vowels. In line with this description, we found differences in the second formant of the preceding vowel and the periodicity of the release for the two allophones. We explore the implications of our findings for the typology of velar laterals.

Purpose The main purpose of this study was to evaluate aging effects on the predominantly subcortical (brainstem) encoding of the second-formant frequency transition, an essential acoustic cue for perceiving place of articulation. Method Synthetic consonant–vowel syllables varying in second-formant onset frequency (i.e., /ba/, /da/, and /ga/ stimuli) were used to elicit speech-evoked auditory brainstem responses (speech-ABRs) in 16 young adults ( M age = 21 years) and 11 older adults ( M age = 59 years). Repeated-measures mixed-model analyses of variance were performed on the latencies and amplitudes of the speech-ABR peaks. Fixed factors were phoneme (repeated measures on three levels: /b/ vs. /d/ vs. /g/) and age (two levels: young vs. older). Results Speech-ABR differences were observed between the two groups (young vs. older adults). Specifically, older listeners showed generalized amplitude reductions for onset and major peaks. Significant Phoneme × Group interactions were not observed. Conclusions Results showed aging effects in speech-ABR amplitudes that may reflect diminished subcortical encoding of consonants in older listeners. These aging effects were not phoneme dependent as observed using the statistical methods of this study.
