Early sine-wave speech (SWS) studies showed that the first three formants contain sufficient intelligibility information. The present work assessed the relative perceptual contributions of the first three formants. Mandarin sentences were edited to generate two SWS conditions: removal of one of the first three formant trajectories, and preservation of only one formant trajectory. In addition, SWS synthesis was implemented in the absence of sine-wave amplitude modulation. The results consistently showed that the trajectory of the second formant contributed the most to intelligibility, and the effect of amplitude modulation was smaller than that of the formant number.
早期的正弦波语音（SWS）研究表明，前三个共振峰包含足够的可懂度信息。本研究评估了前三个共振峰的相对感知贡献。对汉语句子进行编辑以生成两种SWS条件：去除前三个共振峰轨迹中的一个，以及仅保留一个共振峰轨迹。此外，在没有正弦波幅度调制的情况下实现了SWS合成。结果一致表明，第二共振峰的轨迹对可懂度的贡献最大，并且幅度调制的影响小于共振峰数量的影响。
