本文依据《鄂温克语语音声学参数数据库》对前高元音的第一、第二共振峰(F1、F2)进行统计分析。在绘出声学元音图的基础上,通过定量和定性分析确定前高元音的分布格局和音位归属,认为前高元音有[i]、[i:]、[I]、[I:]、[e]、[e:]等六个,可归纳为/i/、/i:/、/I/、/(I:)/四个音位,它们具有较明显的阴阳对立关系。 In this paper, the first and second formants (F1 and F2) of the vowel of the former high were statistically analyzed according to the “Ewenki Speech Acoustic Parameter Database”. On the basis of drawing the acoustic vowel graph, the distribution patterns and phoneme assignments of the front high vowels are determined by quantitative and qualitative analysis. The former high vowels are considered as [i], [i:], [I], [I :], [E], [e:] and other six can be summarized as / i /, /i:/, / I /, / (I:) / four phonemes, which have a more pronounced inverse relationship between yin and Yang .
