One methodological issue in tonal acoustic analyses is revisited and resolved in this study. Previous tone normalization methods mainly served for categorizing tones but did not aim to preserve sociolinguistic variation. This study, from the perspective of variationist studies, reevaluates the effectiveness of sixteen tone normalization methods and finds that the best tone normalization method is a semitone transformation relative to each speaker's average pitch in hertz.
