However, there is anecdotal evidence that it has developed a register contrast, i.e. a binary contrast based on a bundle of spectral properties like pitch, voice quality and vowel quality. We conducted production and perception experiments of the voicing/register contrast in two Jarai varieties spoken in Saom Kaning, Cambodia, and Ea Sup, Vietnam, to determine if they preserve voicing and/or have developed a register contrast. Results show that both dialects have a register contrast primarily based on vowel height modulations (F1) and that onset voicing has become at best an optional secondary property of register. F1 is also the primary cue used for register identification in both dialects. Implications for the diachronic development of the register contrast in Chamic languages and in Mainland Southeast Asia in general are discussed.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Voicing or register in Jarai dialects?

However, in the colloquial speech of the capital Phnom Penh, /r/ is lost in onsets, reportedly supplanted by a range of other acoustic cues such as aspiration, a falling- or low-rising f0 contour, breathy voice quality, and in some cases diphthongization, e.g. /krɑː/ ‘poor’ > [kɔ̀ɑ], [kʰɔ̌ɑ], [kɔ̤ɑ̤], /kru:/ ‘teacher’ > [khùː] [kʰǔː], [kṳː]. This paper presents the results of production and perception studies designed to shed light on this unusual sound change. Acoustic evidence shows that colloquial /CrV/ forms differ from reading pronunciation forms in terms of VOT, f0, and spectral balance measures, while a pair of perceptual studies demonstrate that f0 is a sufficient cue for listeners to distinguish underlying /CrV/-initial from /CV/-initial forms, but that F1 is not.

I show how this incipient tonogenesis might arise in a series of computational simulations tracing the evolution of multivariate phonetic category distributions in a population of ideal observers. Acoustic production data from a fieldwork study conducted in Phnom Penh was used as the starting point for the simulations. After establishing that the basic framework predicted relative stability over time, two possible responses to a phonetic production bias were considered: one in which agents correctly identified the source of (and thereby compensated for) the effects of the bias, and one in which agents misattributed the acoustic effects of the bias as a property of the onset. Good qualitative fits to the empirical production data were found for the latter group of learners, while the outcome for compensating learners resembled production data from a related dialect. These results are consistent with the sudden and discontinuous nature of many sound changes, and suggest that what appear to be enhancement effects may also emerge under different assumptions about the number of cue dimensions accessible to or deemed relevant by the learner.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Incipient tonogenesis in Phnom Penh Khmer: Computational studies","attachmentId":32899231,"attachmentType":"pdf","work_url":"https://www.academia.edu/5920902/Incipient_tonogenesis_in_Phnom_Penh_Khmer_Computational_studies","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/5920902/Incipient_tonogenesis_in_Phnom_Penh_Khmer_Computational_studies"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="71948454" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/71948454/On_the_r_h_shift_in_Ki%C3%AAn_Giang_Khmer_supplementary_materials">On the r>h shift in Kiên Giang Khmer: supplementary materials</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="9129471" href="https://hcmussh.academia.edu/%C4%90inhGiang">Đinh Giang</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2017</p><p class="ds-related-work--abstract ds2-5-body-sm">This paper presents an acoustic and perceptual study of the r&gt;h shift in the variety of Khmer spoken in Giồng Riềng district, Kiên Giang province, Vietnam. In Phnom Penh Khmer, /r/ is realized as [h] in syllable onsets and onset clusters, and accompanied by lowered pitch, breathiness, and in some cases a change in the quality of the following vowel. In Kiên Giang Khmer, the r&gt;h shift is accompanied by pitch lowering, but without changes in aspiration or vowel quality, and spectral measures did not indicate substantial differences in voice quality. Consistent with their productions, users of this dialect appear to rely solely on differences pitch to identify these lexical items. We discuss the implications of our findings for Khmer dialectology, mechanisms of sound change, and variation in the realization of rhotics more generally.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"On the r\u003eh shift in Kiên Giang Khmer: supplementary materials","attachmentId":81082001,"attachmentType":"pdf","work_url":"https://www.academia.edu/71948454/On_the_r_h_shift_in_Ki%C3%AAn_Giang_Khmer_supplementary_materials","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/71948454/On_the_r_h_shift_in_Ki%C3%AAn_Giang_Khmer_supplementary_materials"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="63345829" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/63345829/Chrau_Register_and_the_Transphonologization_of_Voicing">Chrau Register and the Transphonologization of Voicing</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="155765033" href="https://independent.academia.edu/NamH%C3%B2aQu%C3%BD">Nam Hòa Quý</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2019</p><p class="ds-related-work--abstract ds2-5-body-sm">Chrau, a Mon-Khmer language of southern Vietnam, has been described as preserving a voicing contrast in onset stops. Instead of voicing, closely related languages have a register contrast in which voiced and voiceless stops have respectively evolved into breathy and modal registers. Unexpectedly, the Chrau dialect investigated in this paper has a register system based on f0, voice quality and vowel quality, just like its sister languages. However, onset stop voicing is not fully neutralized: stops have a short positive VOT in the modal register, but in the breathy register, they either have closure voicing or a VOT slightly longer than modal register stops. There is no evidence for an acoustic trade-off between voicing and register cues. The preservation of VOT differences in onset stops suggests that Chrau has a conservative register system. We discuss how the cooccurrence of VOT and register cues sheds light on models of registrogenesis.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Chrau Register and the Transphonologization of Voicing","attachmentId":75806253,"attachmentType":"pdf","work_url":"https://www.academia.edu/63345829/Chrau_Register_and_the_Transphonologization_of_Voicing","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/63345829/Chrau_Register_and_the_Transphonologization_of_Voicing"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="75469589" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/75469589/Proto_Mon_Khmer_Vocalism_Moving_on_from_Shorto_s_ALTERNANCES_1">Proto-Mon-Khmer Vocalism: Moving on from Shorto’s ‘ALTERNANCES’1</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="32075765" href="https://independent.academia.edu/SidwellPaul">Paul Sidwell</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2015</p><p class="ds-related-work--abstract ds2-5-body-sm">While we have had a century of more-or-less consensus views on the nature of the Proto-Mon-Khmer (PMK) consonant inventory, cries of exasperation have accompanied consideration of PMK vocalism.
