Languages may differ in fundamental frequency of voicing (f0), even when they are spoken by a bilingual individual. However, little is known in bilingual/L2 acquisition research about simultaneous bilinguals. With the expectation that speakers who acquired two languages early use f0 differently for each language, this study measured f0 in English-Korean early bilinguals' natural speech. The f0 level was higher for Korean than English, regardless of gender, age, or generational status (early and late bilinguals did not differ). The f0 span showed a language-gender interaction: males' span was larger in Korean, while females' span was larger in English. This study demonstrates that languages differ in f0 independent of speaker anatomy and suggests that children may acquire these differences in early childhood.
语言在基频（f0）方面可能存在差异，即使是双语者使用的语言也是如此。然而，在双语/L2 习得研究中，对于同时掌握两种语言的双语者知之甚少。本研究期望那些早期习得两种语言的人会根据语言的不同而以不同的方式使用 f0，因此测量了英语-韩语早期双语者自然言语中的 f0。韩语的 f0 水平高于英语，无论性别、年龄或代际地位（早期和晚期双语者之间没有差异）。f0 跨度显示出语言-性别交互作用：男性的韩语 f0 跨度较大，而女性的英语 f0 跨度较大。本研究表明，语言在 f0 方面存在差异，与说话者的解剖结构无关，并表明儿童可能在幼儿期就开始习得这些差异。
