Abstract
The paper proposes a general, flexible and efficient method for the distribution of time-scale modification Factors. The method is inspired by the analogy with a sequence of springs with different rates/constants, allowing simple and straightforward non-linear distribution of modification factors through the speech to modify. The flexibility and generality of the proposed scheme enables its use for any number of speech/sound segment categories of any type and length, while the modification factors can either be set heuristically, ad-hoc, or trained from data. At the end of the paper, an attempt to use statistics of phone durations to set the modification factors is described and discussed.
