System and method for voice modification

Abstract

A system for conducting voice modification on an audio input signal comprising speech to obtain an audio output signal according to an embodiment is provided. The system comprises a feature extractor for extracting feature information of the speech from the audio input signal. Moreover, the system comprises a fundamental frequencies generator to generate modified fundamental frequency information depending on the feature information, such that the modified fundamental frequency information comprises modified fundamental frequencies being different from real fundamental frequencies of the speech, and/or such that the modified fundamental frequency information indicates a modified fundamental frequency trajectory being different from a real fundamental frequency trajectory of the speech. Furthermore, the system comprises a synthesizer for generating the audio output signal depending on the modified fundamental frequency information and depending on the feature information.
