What are resonance problems in CP most likely to lead to?

Resonance problems, particularly in individuals with cerebral palsy (CP), are most likely to lead to hypernasality. This is primarily due to the fact that these resonance issues can affect how sound travels through the vocal tract, leading to an unintended excess of airflow through the nasal cavities during speech. Hypernasality occurs when there is an imbalance in the nasal and oral resonance, often because of inadequate closure of the velopharyngeal port, which can be a common challenge for individuals with CP.

In contrast, the other options presented do not align with the characteristics of resonance issues in this population. Enhanced vocal clarity, improved sound reproduction, and consistent voice pitch typically indicate well-regulated resonance control and coordination, which is generally not the case when resonance problems are present. The presence of hypernasality serves as an indication of these disturbances, making it the most likely outcome for individuals experiencing resonance problems related to CP.
