Abstract

Voice alteration is the conversion of one speech signal into other, preserving the source content. For Voice alteration, two main parameters of speech must be considered viz. Static and Dynamic. In this paper, only static parameters are considered. The LP coefficients of source and target speech are extracted using LP analysis. The cross mapping of the extracted parameters is achieved by modifying source parameters in line with the target parameters using TD-PSOLA. Results illustrate that the TD-PSOLA method is reliable and efficient approach for voice alteration. The voice alteration system thus developed can contribute greatly to the Medical and Entertainment Industry where specific voice is essential.
