A fluency aid 1 for users with a stammer, stutter or other speech impediment in logopedic therapy comprises a user-operated ON switch 20 which causes a masking sound (eg. white noise) and haptic output to be generated or faded out under the control of a Voice Activity Detection (VAD) module 40. Altered Auditory Feedback (AAF, 50 fig. 2) may be provided based on the detected voice, and a pacing signal (eg. a click or metronome, 60 fig. 3) may be generated at regular intervals.
