Objective consonant evaluation using palatograph tracing and digital acoustic assessment methods are valuable tools for speech assessment that can be used to track speech improvement in patients wearing a removable prosthesis. In this case report, we employed the psychoacoustic parameter – sharpness - to compare the quality of consonants in a cleft palate patient while wearing the old prosthesis, the new prosthesis, and the new prosthesis following palatogram guided modification. The result suggests that sharpness can be successfully analyzed as a criterion to monitor consonants quality during prosthesis fabrication for cleft palate patients.
