ProZed. A prosody editor for linguists

ProZed is a tool designed to allow linguists to manipulate the prosody of an utterance via a symbolic representation in order to evaluate linguistic models. Prosody is manipulated via a Praat TextGrid which allows the user to modify the rhythm and melody. Rhythm is manipulated by factoring segmental duration into three components: (i) intrinsic duration determined by phonemic identity (ii) local modifications encoded in the Rhythm unit and (iii) global variations of tempo encoded in the Intonation Unit. Melody is similarly determined by tonal segments in the Tonal Unit (corresponding to pitch accents) and the Intonation Unit (corresponding to boundary tones) together with global parameters of \\emph{key} and \\emph{span} determining changes of pitch register. The TextGrid is used to generate a Manipulation object which allows an immediate interactive assessment of the prosody determined by the annotation.
