Their vocal quality is better than non-passerine, but still much less than oscine passerine. Compared with non-passerine, they appeared longer syllable length, higher basic frequency and more viable frequency ranges. Though the amplitude modulation properties enhanced their vocal production, the type of syllable is still stable and less of variety. So thephrase consisted of syllables are comparatively few and changes of the tone are relatively less.
且表现出很强的频率调制特性和特有的幅度调制特性，相对的音节时程比较长，基频较高且频率变化范围较大，所特有的幅度调制特性更增加了其控声的能力，但其音节的种类仍很单一，缺乏变化，由音节所组成的句型较少，音调变化幅度不大，因此，其叫声质量尽管较非鸣禽有所改善，但相对鸣禽而言却又远远不如。

The calls of non-passerine are some kinds of monotonous dull vocalizations with the characteristics of low and deep frequency, single syllable, low basic frequency and with no ability of modulation in frequency and amplitude. Most of the calls are monotonous and low quality mainly based on the basic song. Compare the vocal of sub-oscine passerine with non-passerine, they have some similar aspects, but the former possesses of stronger capability of vocal control.
非鸣禽的叫声低沉而单调，音节种类单一，基本音频率低，缺乏频率调制以及幅度调制的能力，叫声的品质因数很低，不悦耳，大多为以基本音为主的单音调低音品叫声，亚鸣禽的叫声与非鸣禽近似，但在控声能力方面又有所提高。
