In analyzing physiological signals related to speech, it is necessary to average several repetitions in order to improve the signal-to-noise ratio. However, in a recent experiment, considerable differences were found in the articulation rate of repeated realizations of a medium length utterance, especially for untrained subjects. This makes averaging of related physiological signals a non-trivial problem. A new method of time-alignment and averaging of the physiological signals is described. In this method a dynamic programming algorithm is used, which successfully corrects for the timing differences among the repetitions.
