Fluency Disorders

Fluency means uninterrupted and smooth flow of sounds, syllables, words and phrases when put together while speaking.

If dysfluencies are observable then one must consult a Speech Language Pathologist or Speech Therapist.

Most common fluency disorders are stuttering and cluttering.


Stuttering also known as stammering.

Stuttering is a most common fluency disorder in which continuity of speech flow is interrupted.

Stuttering is characterized by interruptions such as repetitions, prolongations, blocks, hesitations and secondary behaviours.

Person with stuttering knows what he/she wants to say but has trouble speaking in a flowing way (effortful).

Stuttering symptoms increases when the person is excited, tired or under stress, or when feeling self-conscious, hurried or pressured.

A stutter feels difficulty speaking in front of a group or talking on the phone.


Cluttering is a speech, language and communication disorder characterized by irregular speech rate, jerky speech, erratic rhythm, and poor syntax or grammar, making speech difficult to understand.

Cluttering is also characterized by slurred speech.

Clutterer can put thoughts into words but cannot organize thoughts while speaking to produce fluent speech.

A clutterer is usually unaware of his/her speech dysfluencies.

Cluttering is often misdiagnosed as stuttering.
