The system addresses the critical gap in Automatic Singing Assessment (ASA) for microtonal music, particularly Kurdish maqams. Existing ASA tools, built on Western music rules, incorrectly identify micro-intervals and pitch bends as errors. Our deep learning model, focused on Bayati-Kurd, accurately detects fine pitch, rhythm, and modal drift errors, providing culturally relevant feedback. We developed a custom corpus of 50 songs with 221 annotated error spans and trained a CNN-BiLSTM with attention for detection and classification.

Case Study: Empowering Maqam Learning with AI
A music academy struggled to provide consistent, personalized feedback to its Bayati-Kurd maqam students due to limited expert availability. Implementing our AI-powered vocal error detection system, students gained access to instant, specific feedback on fine pitch, rhythm, and modal drift errors. This resulted in a 20% faster skill acquisition for identified error types and a significant reduction in the training burden on instructors, allowing them to focus on advanced artistic nuances rather than basic error correction.
