Abstract
This paper describes the implementation of the PSOLA algorithm for two mobile platforms with embedded operating systems: Android and iOS. In order to mask the voice identity of a telephony subscriber using a virtual voice, a modification of the time scale of the utterance and of the pitch of the speaker have been implemented, with the influence of these modifications on the recognition of the identity by listeners being studied. Mobile platforms were compared in terms of signal processing time, including the read and write times.
