TONE-INTERVAL INTERFACE 協音指南
團隊早前與粵語母語使用者進行聆聽實驗。實驗者需要為每個粵語聲調組合辨識協音音程(函蓋大九度,即十四個半音距離之內的所有音程)。以下為部分實驗數據。

m2 = minor 2nd; M2 = major 2nd; m3 = minor 3rd; M3 = major 3rd; P4 = perfect 4th; A4 = augmented 4th; d5 = diminished 5th;
P5 = Perfect 5th; m6 = minor 6th; M6 = major 6th; m7 = minor 7th; M7 = major 7th; P8 = Octave; m9 = minor 9th; M9 = major 9th
*Intelligible Intervals: intervals that over 75% of respondents considered intelligible for at least one of its occurrence in a diatonic scale.
協音音程:即研究中有超過75% 測試對象,能夠在自然音階中從至少一組唱名組合的音程辨識到正確的聲調組合。
