Item Características acústicas del fonema alveolar sordo /S/ en población con fisura labio palatina: Reporte de casos(Universidad Santiago de Cali, 2020) Aragón Rentería, Belquin Rosany; Cardozo León, Nathalia; Sánchez Mejía, Francy Daniela; Arguello Vélez, Patricia (Directora)This research makes a report of 13 clinical cases describing: type of fissure, speech therapy diagnosis, number of surgeries to correct the fissure, presence or not of velopalatine insufficiency, integrity of anatomical structures such as: nasal and oral cavity, nasal patency and presence or not of articulatory compensations of the phoneme / s /, where the clinical database registered in the thesis registered in 2019 was taken as a reference: case report. In addition, it shows the acoustic characteristics of the deaf alveolar fricative phoneme / s / in people with cleft lip and palate, analyzing it through the PRAAT software, which provides acoustic data which can facilitate objective evaluation and diagnosis, as well as measure the therapeutic evolution and effectiveness of the speech therapy; this acoustic parameter can be projected as an indicator of the effectiveness of velopharyngeal closure and its impact within the joint of the phoneme being evaluated or treated. The object of study was the deaf alveolar fricative phoneme / s /, which is called fricative due to the friction produced in the passage of air with the teeth and lips; it is also deaf since the sound is air and there is no vibration of the vocal cords at the moment of articulation. This phoneme was chosen, since it is the only one of the fricatives that provides height of stridency within the acoustic characteristics, which provides articulatory information in relation to clinical correlates such as dental occlusion, palatal integrity and oral resonance. The analysis of the phoneme was carried out using the PRAAT Software, which yielded acoustic and articulatory behavior values, which were objectively analyzed.
