S/Z

S/Z is a linguistic tool used by speech-language pathologists to analyze speech patterns, specifically focusing on the frequency and nature of the "s" and "z" sounds. By examining these sounds in a person's speech, S/Z analysis helps identify issues like excessive or abnormal production of these sounds, which can indicate underlying speech or respiratory conditions. The test involves measuring how long a person can sustain each sound, providing insights into airflow, vocal function, and potential speech disorders. It’s a useful diagnostic method for assessing and planning treatment for speech clarity and fluency.
