This paper documents the acoustic effects of onset and coda consonants on the F0 trajectory of the preceding vowel in the Austroasiatic language Eastern Khmu. In addition to an onset voicing contrast, Eastern Khmu permits syllables ending in sonorants, unreleased plosives, a voiceless glottal fricative, and a glottal stop. While glottal stop and fricative codas are frequently implicated in tonogenesis, their coarticulatory effects on the pitch of the preceding vowel are reported to vary. Here, we analyze data from 20 speakers of Eastern Khmu producing monosyllables in which both onset voicing and coda type were varied. Growth curve analysis indicates that, relative to sonorant-final syllables, the presence of a non-sonorant final raises F0 of the preceding vowel for syllables with both voiced and voiceless onsets. Onset F0 effects are also visible in syllables with voiceless onsets, regardless of coda type. Coda-induced variations in the shape of the F0 trajectory are detectable early in the F0 excursion, a conclusion validated by a neural network classifier. We propose that the co-intrinsic effects of codas can impose a laryngeal setting affecting the F0 trajectory of the entire preceding syllable. We discuss the implications of these findings for classical models of tonogenesis.
