A fluency aid 1 for users with a stammer, stutter or other speech impediment in logopedic therapy comprises an audible pacing signal generator 10 (eg. a regularly timed click or tone) which can be faded out under the control 20 of a Voice Activity Detection (VAD) module 60a. A masking sound (eg. white noise) may be generated in conjunction with the click whose volume may depend on the loudness of the detected voice or ambient noise, and Altered Auditory Feedback (AAF) may be provided based on the detected voice.
