Time-domain harmonic scaling

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]

History

Proposed by D. Malah in 1979^[4]
