We present a novel efficient algorithm for time-scale
modification (TSM) of speech which gives output
quality equal to that of a conventional TSM algorithm,
but having computational load an order of magnitude
less. The algorithm presented uses a fixed length
rectangular stepping window and a simple peak
alignment criterion to track the local natural scaling
factor and adapt the window step size. The desired
TSM factor is realised by the appropriate number of
applications of the constantly varying local natural
scaling factor. The local natural scaling factor estimate
is updated at sub-pitch period intervals giving accurate
pitch tracking and high quality in the output scaled
signal.
