A Strategy for Pitch Conversion and Its Evaluation
نویسندگان
چکیده
In order to transform the perceived speaker identity, a voice conversion system should, a.o., convert the speaker’s prosodic characteristics. When considering pitch contours, most systems only transform the pitch by simple scaling. A stochastic system that transforms pitch contours taking into account multiple pitch parameters has been developed and is described. A pitch transplantation system based on the overlap-add (OLA) algorithm is proposed as a tool for the evaluation of this pitch conversion system.

متن کاملStatistical Conversion Algorithms of Pitch Contours Based on Prosodic Phrases
Pitch contour of a speech utterance plays an important role in expressing speaker's individuality and meaning of the utterance. In performing speech conversion from a source speaker to a target speaker, it is important that the pitch contour of the source speaker’s utterance be converted into that of the target speaker. This paper investigates statistical algorithms of pitch contour conversion ...

One of the main tasks of the control systems in the wind turbines is to maintain the power of the wind when its wind speed proceed its nominal value. Because the failure to maintain the power in its nominal value in the region of the turbine curve damages the turbine and increases the mechanical stress. This object is obtained by controlling the pitch angle in the third region of the turbine cu...
