In this paper, a system for real-time recorded speech time and pitch scaling by the means of hands or feet gestures is designed and evaluated. Pitch is controlled with the preferred hand, using a stylus on a graphic tablet. Time is controlled using rhythmic frames, or constriction gestures, defined by pairs of control points. The " Arsis " corresponds to the constriction (weak beat of the syllable) and the " Thesis " corresponds to the vocalic nucleus (strong beat of the syllable). This biphasic control of rhythmic units is performed by the non-preferred hand using a button. Pitch and time scales are modified according to these gestural controls with the help of a real-time pitch synchronous overlap-add technique (RT-PSOLA). Rhythm and pitch control accuracy are assessed in a prosodic imitation experiment: the task is to reproduce intonation and rhythm of various sentences. The results show that inter-vocalic durations differ on average of only 20 ms. The system appears as a new and effective tool for perfor-mative speech and singing synthesis. Consequences and applications in speech prosody research are discussed. %G English %2 https://hal.sorbonne-universite.fr/hal-01672232/document %2 https://hal.sorbonne-universite.fr/hal-01672232/file/delalez-dalessandro-IS17.pdf %L hal-01672232 %U https://hal.sorbonne-universite.fr/hal-01672232 %~ SHS %~ CNRS %~ UNIV-PSUD %~ AO-LINGUISTIQUE %~ AO-MUSICOLOGIE %~ LIMSI %~ IJLRDA %~ UNIV-PARIS-SACLAY %~ IJLRDA-LAM %~ UNIV-PSUD-SACLAY %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ TEST-HALCNRS %~ SU-TI %~ ANR %~ LISN %~ GS-ENGINEERING %~ GS-COMPUTER-SCIENCE %~ COMUE-UPSACLAY %~ ALLIANCE-SU %~ MUSCI
