Cluttering is a communication disorder resulting in decreased fluency and intelligibility that often coexists with stuttering.
An exact description of cluttering has not been accepted or agreed upon universally. In general, it is a communication disorder that results in decreased speech intelligibility and may involve one or a combination of the following areas: language, articulation, and fluency, as well as rate and self-monitoring skills.
The characteristics of cluttering vary among clients, but a consistent characteristic is an excessive speech rate. More than 60 other symptoms are listed in well-known chapters and books on cluttering. Some common characteristics include:
-Indistinct, “mumbling” speech involving sound distortions and omissions.
-Errors in connected speech that are not present or less pronounced in single-word production or connected speech that is produced slowly.
-Transpositions of sounds in words, phrases, or sentences (ex: “Many people think so” becomes “Many thinkle peep so”)
-Auditory processing difficulties
-Client may be unaware of his/her speech disorder and surprised when other people do not understand him/her
Stuttering vs. Cluttering
- Disfluencies on units smaller than the word level, such as sound prolongations and sound/syllable repetitions
- Effort/physiologic tension associated with disfluent moments
- Typically person has awareness of disfluencies and a sense of loss of control
- Difficulty making fluent transitions from one sound or syllable to the next.
- Disfluencies typically involve units larger than the sound or syllable level, such as word and phrase repetitions, incomplete phrases, and revisions.
- Little apparent physiologic tension
- Often demonstrate poor self-monitoring skills and decreased awareness of speech errors
- Difficulty making smooth transitions from one syntactic unit to another or one lexical choice to the next or sequencing his/her message cohesively and coherently
- Do not typically produce prolongations or tense pauses
- Fast and/or spurty speaking rate
- Linguistic encoding difficulties leading to poor cohesion and coherence of connected speech
- Reduced speech intelligibility due to articulation errors secondary to fast rate
Diagnosing this disorder:
Since cluttering affects articulation, language, voice, and fluency, its assessment includes each of these areas.
-Individuals may not clutter in all situations. Important to examine in several contexts: Reading lists of multisyllabic words, Reading passages, Spontaneous speech
-Rate language/speech samples for:
– Overall speech rate
– Regularity of rate
– Overall articulation accuracy
– Pragmatic language appropriateness
-Interview client regarding perception of speech difficulty and perception of social penalty of speech difficulty
-Writing sample analysis
– Short paragraph about vacation, etc.
- Looking for illegible writing
- Omissions of letters, syllables, words, as seen in speech
Two fluency-enhancing strategies can be useful in addressing cluttering: prolonged speech and reduced speech rate.
ASHA outlines that therapy should focus on:
Slowing rate (metronome, pacing boards, visuals, etc.)
- Use video or audio-taped conversations and have client identify places where he/she failed to monitor.
- Prepare samples of worst, mediocre and best speech, have them listen/rate daily to assist with ability to monitor on-line.
Using clear speech
- “over-articulate“ multisyllabic words/ discuss what they are feeling
- Imagine they are talking to a person with hearing loss
Using organized language
- Example: focusing on one topic at a time
Interacting with listeners
- taking turns in conversation at reasonable durations (such as 30 seconds)
- thinking about the listener as you speak
Reducing excessive disfluencies
- identifying mazes in his/her speech
Also important to work with parents on modeling clear speech and organized language.
