Time-domain harmonic scaling (TDHS) is a method for time-scale modification of speech (or other audio signals),[1] allowing the apparent rate of speech articulation to be changed without affecting the pitch-contour and the time-evolution of the formant structure.[2] TDHS differs from other time-scale modification algorithms in that time-scaling operations are performed in the time domain (not the frequency domain).[3] TDHS was proposed by D. Malah in 1979.[4]
