本研究旨在探讨麦克风类型(动态与冷凝器)和模式(全方位与心形)对持续发声的语音扰动措施提取的影响。声源和麦克风之间的距离和角度的影响也令人感兴趣。选择了四个专业级麦克风和两个消费级麦克风进行分析。在100赫兹和300赫兹的基频下，通过扬声器呈现了不同幅度和频率调制的合成发声。人类发声也被包括在内，以测试扬声器演示的有效性。麦克风的放置采用三个距离(4 cm、30 cm、1 m)和三个角度(0°、45°、90°)。在专业级传声器中，心形电容式传声器对微扰测量的影响最小。一般而言，冷凝器类型比动态类型提供更好的结果。输出不平衡的麦克风表现不如输出平衡的麦克风。麦克风灵敏度和距离对干扰措施的影响最大，除了距离嘴几厘米外，很难解决正常的声音抖动。角度对短距离的影响不大，但对长距离的影响更大。这些结论是初步的，因为麦克风、距离和信号类型的采样非常粗糙。这项研究只是为今后的工作指明了方向。
This study was conducted to explore the effects of microphone type (dynamic vs. condenser) and pattern (omnidirectional vs. cardioid) on the extraction of voice perturbation measures for sustained phonation. Also of interest were the effects of distance and angle between the source and the microphone. Four professional-grade and two consumer-grade microphones were selected for analysis. Synthesized phonation with different amplitude and frequency modulations at fundamental frequencies of 100 Hz and 300 Hz were presented over a loudspeaker. Human phonation was also included to test the validity of loudspeaker presentations. Three microphone distances (4 cm, 30 cm, 1 m) and three angles (0°, 45°, 90°) were used for microphone placement. Among the professional grade microphones, the cardioid condenser type had the smallest effect on perturbation measures. In general, condenser types gave better results than dynamic types. Microphones with an unbalanced output did not perform as well as those with balanced outputs. Microphone sensitivity and distance had the largest effect on perturbation measures, making it difficult to resolve normal vocal jitter at anything but a few centimeters from the mouth. Angle had little effect for short distances, but a greater effect for longer distances. These conclusions are preliminary because the sampling of microphones, distances, and signal types was very coarse. The study serves only to chart the course for future work.
