Voice intensity levels produced by 20 patients with cuffed speaking tracheostomy tubes (Communi‐Trach I ® ) at three different airflow rates were investigated. Results indicated that audible and intelligible speech was produced with significantly greater intensity over ambient room noise at 5 l/minute, 10 l/minute, and 15 l/minute of airflow. Criteria for use, common causes of malfunctioning, and rehabilitation techniques necessary for the successful use of cuffed speaking tracheostomy tubes are discussed.
