Speaker-normalized Acoustic Distance for Japanese Pitch Accent: Design Principles and Evaluation

Year: 2026

Type: software

Abstract: Code and materials for a speaker-normalized acoustic distance that positions Japanese speakers along documented pitch-accent gradients. Axis poles are anchored in independent phonological descriptions of four canonical accent varieties (Tokyo, Kansai, Tarui, Kagoshima). Includes the F0 normalization pipeline (semitone + MAD z-scoring), the Sakoe-Chiba constrained DTW distance, baseline metrics (mean F0, histogram EMD, wav2vec 2.0), and the gradient-preservation evaluation on 68 speakers from Kashiwabara (intermediate Tarui zone).
