契丹小字中的音译基本不显示汉语的声调区别，但有三种特殊拼写却和汉语去声音节有关，两个与去声有关的声调变化现象也可以证实这一点：一是中古全浊声母上声音节变成了去声；一是中古次浊声母入声音节变成了去声。因此，契丹小字材料中所观察到的次浊入声音节声调变化要比1324年的《中原音韵》中所记录的早了至少200多年。

The Khitan Language, a member of the Altaic language family, is a non-tonal language. It is thus not expected that tonal distinctions of Chinese will be reflected in the transcriptions of the Khitan Lesser Script. However, it is quite surprising that there are three types of special spellings related to Chinese qu-tone syllables. Based on the identification of the special spellings of qu-tone syllables two tonal changes related to the qu tone can be confirmed. One is that the MC shang-tone syllables with voiced obstruent initials have changed to qu-tone, and the other is that the MC ru-tone syllables with sonorant initials have changed to qu-tone. It is worth noting that the tonal change of the ru-tone syllables with sonorant initials observed in the Khitan Lesser Script is at least more than two hundred years earlier than what is recorded in the Zhongyuan Yinyun of 1324.
