In spoken communication, intonation often conveys meaning of an utterance. Thus, incorrect intonation, typically made by second language (L2) learners, could result in miscommunication. We demonstrate In-SPIRE tool that helps the L2 learners to learn intonation in a self-learning manner. For this, we design an interactive self-explanatory front end, which is also used to send learner`s audio and hand-shake signals to the back-end. At the back-end, we implement a system that takes the learner`s audio against a specific stimuli and computes pitch patterns representing the intonation. For this, we apply pitch stylization on each syllable segment in the audio. Further, we compute a quality score using the learner`s patterns and the respective ground-truth patterns. Finally, the score, the patterns of the learners and the ground-truth are sent to the front-end for display as a feedback to the learners. Thus, the learner could correct any mismatch in his/her intonation with respect to the ground-truth. The proposed tool benefits the learners who do not have access to effective spoken language training.
