Note. The capital letters—F0, (Δ)PITCH, DUR, and INT—denote the acoustic parameters, that is, F0, voice pitch (change), duration, and intensity. The component that follows each refers to the specific measurement made, for example, at a single point (valley, peak, onset, and offset) or by taking the mean, range, or ratio. The last part of the abbreviated form refers to the location where the measurement is made (utterance-final word, non-utterance-final words, and utterance).
