This paper presents new achievements done with our Calliphony software [1, 2] which allows for real-time modification of the intonation and rhythm of speech, driven by manual control of both fundamental frequency and time scaling either independantly or conjointly. We will present here the main features of the software and discuss possible use for prosody research.

Index Terms: intonation modification, rhythm modification, speech synthesis, prosody analysis, gestural control.
