 Fluency shaping therapy, also known as "speak more fluently", "prolonged speech", or "connected speech", trains people who stutter to speak less disfluently by controlling their breathing, phonation, and articulation (lips, jaw, and tongue).It is based on operant conditioning techniques.People who stutter are trained to reduce their speaking rate by stretching vowels and consonants, and using other disfluency-reducing techniques such as continuous airflow and soft speech contacts.
