This study examines phonation in utterance-final vowels in two dialects of Peninsular Spanish in two prosodic contexts: the end of intermediate phrases (ip), and the end of intonational phrases (IP). Non-modal phonation, like creaky voice and breathy voice, is understudied in Spanish Garellek and Keating, 2015; González et al., 2022, 2024; Gordon and Ladefoged, 2001. Creaky voice has slow, more constricted vibration, while breathy voice allows more airflow with less constricted vibration Esling et al., 2019, Data from an elicitation task of 10 participants was examined acoustically using waveforms and spectrograms in Praat following Spanish ToBi Aguilar et al., 2009; Boersma and Veo una boca ip y una nariz (“I see a mouth and a nose”) in the ip context. Chi-Square tests were performed in SPSS. Based on results from six speakers, while breathy voice is pervasive in both dialects (Burgos 46%, Málaga 39%), there is a significant difference in creaky voice, being more prevalent in Burgos (26.4%) than Málaga (5.3%). Additionally, both creaky and breathy voice differ significantly in both prosodic contexts (p 0.001).
