Abstract: Western Katu (kuf) is an Austroasiatic language, belonging to the Katu subgroup of the Katuic branch (Sidwell, 2015, 2021). According to Eberhard, et.al. (2022), Western Katu (hereafter, Katu) is a variety of Katu spoken by nearly 30,000 speakers in Xekong province, southeastern Lao P.D.R. This study compares descriptions of Proto-Katuic (PK) phonology presented by Sidwell (2005) and Gehrmann (2018), a brief phonological sketch of Katu outlined by Costello and Sulavan (1996), and a roughly 1500-item word list elicited from a 25-year-old Katu woman living in Pakse, Lao P.D.R. Various differences from the previously published phonological descriptions of Katu are proposed. Katu is noteworthy among the Katuic languages for being a non-registral language that conservatively preserves the VOT-based onset voicing contrast reconstructed for Proto-Katuic and for Proto-Austroasiatic (Diffloth, 1982; Huffman, 1976; Sidwell, 2005). This study undertakes an acoustic investigation of potentially redundant cues to the voicing contrast, which would indicate Katu is entering the process of registrogenesis. Word pairs demonstrating a voicing contrast between monosyllabic main-syllable onsets in identical or analogous environments were selected as a subset of the data. Three tokens for each word were annotated to indicate the onset of voicing and consonant and vowel segments. Plots modeling VOT, pitch/F0, vowel quality/F1, spectral tilt, and cepstral peak prominence were produced, the results of which suggest that VOT reliably cues the contrast between voiced and voiceless onsets, and that Katu is not in an early stage of registrogenesis.
