Design and Development of an Indian Classical Vocal Training Tool

When learning any form of classical music vocals without a teacher, even subtle deviations can lead to wrong training, which can be difficult to remedy in future. We are developing a real-time tool to deal with this situation by assisting people in learning Indian Classical Music. This tool will have a set of pre-defined Swaras, Alankaras, and Ragas (Indian Classical Music concepts). Users can practice any musical piece from this set and the tool will inform them of the mistakes they make, by smartly matching their voice with the dynamically defined pattern. Users are free to sing in any given scale, which they define in the beginning by singing the root note of their preferred scale. Using PredominantPitchMelodia Algorithm, the tool identifies the pitch of the musical piece and for pattern identification of the musical piece, it implements k-means clustering algorithm. We propose that Voice Stability and Pitch Accuracy could serve as the evaluation criteria. The functioning of the tool is testified on a varied range of audio samples, namely, male and female voices, and Harmonium audio samples.
