The Effect of Temporal Manipulation on the Perception of Disfluencies as Normal or Stuttering.

Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more representative of stuttering. (Contains references.) (Author/DB)
