3. INTRODUCTION
Fluency – derived from Latin word ‘Flure’
Fluent speaker - some one whose speech is easy and that flows from
word to word without effort
The speech flows easily and smoothly in terms of both sound and
information
There are no disruptions of the message and the listener can attend
to the message
4. DEFINITION
Fluency: “People who are fluent are so skilled in the performance of
speech and language behaviors that they don't need to put much
thought or energy into talking.“
( Stark Weather, 1987 )
6. LINGUISTIC FLUENCY (LANGUAGE)
Syntactically fluent: able to construct highly complex sentences using variety of
complex forms.
Semantically fluent: Speakers are readily able to possess large vocabularies.
Phonologically fluent: Speakers are able to pronounce long and complicated
sequence of sounds and syllables.
Pragmatically fluent: Make timely and appropriate verbal responses in a variety
of social and cultural contexts.
7. SPEECH FLUENCY
CONTINUITY
Speech is continuous if it flows without hesitation/stoppage/disfluencies
Pauses/hesitations – filled/unfilled pauses
Filled Pause - Neutral/meaningless sounds (‘um’, ‘er’, ‘uh’, ‘ah’)
Unfilled pause- silence
Goldman-Eiler (1968), Clarke (1971)
• Conventional pauses – used for emphasis or linguistic purpose
• Idiosyncratic pauses – uncertainty over word choice, style or syntax – more
common in spontaneous speech, longer, complex utterances
8. RATE
Refers to the speed in which the words are spoken
According to speaking task, there is considerable variability in rate in terms of
such factors as formality of speaking situation, time pressure,…
Rate is measured in terms of words or syllables per minute (WPM/SPM)
For Hindi-speaking adults, the mean overall speaking rate is 120 - 130
words/minute (wpm)
9. DURATION
Relates closely to the co articulation of the segments
The duration of CV of a language varies considerably with speech rate and
phonetic and linguistic context
Stressed syllables - longer than unstressed (Umeda, 1975)
10. EFFORT
It refers to the ease with which an act is performed
Stark weather (1987) distinguishes 2 types of effort:
- Physical effort (Muscle movement)
- Mental effort (Linguistic planning)
Mental effort: encoding process, difficult to measure
Physical effort : Refers to action in respiratory, articulatory and laryngeal
system.
12. STUTTERING
Stuttering is the most common fluency disorder , is an interruption in the flow
of speaking characterized by repetitions (speech , syllables , words , phrases ) ,
sound prolongations , blocks , interjections and revisions , which may affect the
rate & rhythm of speech .
These disfluencies may be accompanied by physical tension , negative reactions
, secondary behaviors & avoidance of sound , word or speaking situations .

14. NEUROGENIC STUTTERING
Neurogenic stuttering is a type of fluency disorder in which a person has
difficulty in producing speech in a normal, smooth fashion. Individuals with
fluency disorders may have speech that sounds fragmented or halting, with
frequent interruptions and difficulty producing words without effort or struggle.
Neurogenic stuttering typically appears following some sort of injury or disease
to the central nervous system i.e. the brain and spinal cord, including cortex,
sub-cortex, cerebellar, and even the neural pathway regions.

15. CLUTTERING
Cluttering is a fluency disorder characterized by a rapid or irregular speaking rate
, excessive dys-fluencies & often other symptoms such as language or
phonological errors & attention deficits .
Characterized by repetitions of 6-10 units , poor concentrations , short attention
span , perceptual weakness , poorly organized thinking , jerky respiration ,
delayed speech / late talking .
