An automatic intonation classifier for L2 English speech is proposed RULF labels are proposed to transcribe an intonation as rising, upper, lower or falling Pitch contour from final pitch accent to the end of intonational phrase(IP) is important for intonation classification Intonation classifier works well, even if we only consider 8 frames of pitch values prior to the end of pitch contour
