JSnoori

JSnoori is written in Java and uses signal processing algorithms developed within WinSnoori software with the double objective of being a platform independent signal visualization and manipulation tool, and also for designing exercises for learning the prosody of a foreign language. JSnoori thus focused the calculation of F0, the forced alignment of non native English uttered by French speakers and the correction of prosody parameters (F0, rhythm and energy). Since phonetic segmentations and annotations play a central role in the derivation of diagnosis concerning the realization of prosody by learners, several tools have been incorporated to segment and annotate speech. In particular, a complete phonetic keyboard is available, several kinds of annotation can be used (phonemes, syllables and words) and forced alignment can exploit variants to cope with non native accents. In addition, JSnoori offers real time F0 calculation which can be useful from a pedagogical point of view.
