Muscle Tension Dysphonia (MTD) changes how you produce your voice due to excess muscle tension. The muscles in and around your larynx may be affected. This condition may or may not affect the sound of your voice. It is often a “secondary” problem but does occur by itself.
MTD is within the Functional Class of Voice Disorders and often responds well to external changes (e.g., improving your environment) and internal “motor” behavior changes. Some of the symptoms of MTD include: 
Increased effort when vocalizing The sensation of squeezing or pushing in the throat or neck Increased tension in the upper body Pain in the throat, particularly during Phonation (vocalizing) Feeling as if the throat is tired when speaking or singing The voice cannot get louder or softer or even both The voice may be rough or raspy Problems singing notes that used to be easy Voice cutting out Feeling winded Treatment MTD is usually treated with voice therapy. The speech therapist will help you to decrease the tension in your throat and increase “vocal efficiency.” Methods to achieve greater vocal ease will include exercises designed to increase awareness of how you produce your voice, increase your ability to care for and maintain your voice, breathe more efficiently during phonation, or loosen the muscles around your larynx.
You must perform exercises regularly. You are encouraged to record sessions to help you practice at home.
If you participate in therapy through a virtual or video session, please ensure you can sit or stand well-supported and have tools such as straws, water, kazoos, or other items your clinician has prescribed to assist your therapy.
