Using naïve listener imitations of native speaker productions to investigate mechanisms of listener-based sound change by Carignan, Christopher

“…This study was designed to test whether listener-based sound change—listener misperception (Ohala, 1981, 1993) and perceptual cue re-weighting (Beddor, 2009,…”

A comparison of acoustic and articulatory methods for analyzing vowel differences across dialects: Data from American and Australian English by Blackwood Ximenes, Arwen, Shaw, Jason A., Carignan, Christopher

“…In studies of dialect variation, the articulatory nature of vowels is sometimes inferred from formant values using the following heuristic: F1 is inversely…”

The origins of babytalk: smiling, teaching or social convergence? by Kalashnikova, Marina, Carignan, Christopher, Burnham, Denis

“…When addressing their young infants, parents systematically modify their speech. Such infant-directed speech (IDS) contains exaggerated vowel formants, which…”

Perceptual identification of oral and nasalized vowels across American English and British English listeners and TTS voices by Gwizdzinski, Jakub, Barreda, Santiago, Carignan, Christopher, Zellou, Georgia

“…Nasal coarticulation is when the lowering of the velum for a nasal consonant co-occurs with the production of an adjacent vowel, causing the vowel to become…”
