以前的研究表明，歌手修改发音是为了避免基音频率F0超过第一共振峰F1的正常值(正常)。用5帧/S的磁共振成像技术，分析了一位专业女高音演唱从C4到G5(262-784赫兹)的元音/i、e、u、o、a/的上行三和弦模式的清晰度。测量并分析了唇颌张开度和舌背高度随螺距变化的规律。音高以下四个或五个半音，其中F0=F1(正常)，舌背高度在/i，e，u，a/中降低，而在/o/中唇口加宽，在/a/中下巴开口也变宽。在较高的音调下，所有元音的下巴张开都是扩大的。这些发音动作可能会提高这些元音中的F1。
Previous studies suggest that singers modify articulation to avoid that the pitch frequency F0 exceeds the normal value of the first formant F1(Normal). Using magnetic resonance imaging at a rate of 5 frames/s, articulation was analyzed in a professional soprano singing an ascending triad pattern from C4 to G5 (262-784 Hz) on the vowels /i, e, u, o, a/. Lip and jaw opening and tongue dorsum height were measured and analyzed as function of pitch. Four or five semitones below the pitch where F0 = F1(Normal) the tongue dorsum height was reduced in /i, e, u, a/, whereas in /o/ the lip opening was widened and in /a/ also the jaw opening was widened. At higher pitches, the jaw opening was widened in all vowels. These articulatory maneuvers are likely to raise F1 in these vowels.
