背景除了双语者和单语者之间基频的语言差异外，研究还包括其他声学参数，以分析与所讲语言相关的声音产生差异。瞄准目的：探讨单语者和双语者在英语制作过程中语音声学参数的差异。探索性横断面研究，两组受试者：单语英语发言者（n = 40），和双语英语-西班牙语发言者（n = 13）。参与者填写问卷并在无噪声和中等混响时间（0.8秒）的“虚拟模拟”声学条件下用英语记录一次阅读（彩虹段落的第二句“彩虹是将白色光划分为许多美丽的颜色”）。按性别分析表明，单语者有较高的基频模式，和较低的标准差的基频相比，双语英语-西班牙语的发言者。双语男性说话者比单语说话者有更高的抖动和谐波噪声比。相反，女性双语者比单语者有更低的抖动和闪烁。讲第二种语言可能会影响语音声学参数，因此，在比较声学语音指标时应予以考虑。
Background. In addition to language differences in fundamental frequency between bilinguals and monolinguals, studies have also included other acoustic parameters to analyze differences in voice production associated with the language spoken. Aim. To identify differences in voice acoustic parameters during English productions between monolingual and bilingual English speakers.Method. Exploratory cross-sectional study with two groups of subjects: monolingual English speakers (n = 40), and bilingual English-Spanish speakers (n = 13). Participants filled out a questionnaire and recorded one reading in English (second sentence of Rainbow passage "The rainbow is a division of white light into many beautiful colors") under a "virtual-simulated" acoustic condition of No Noise and Medium Reverberation Time (0.8 seconds).Result. Analysis by gender shows that monolingual speakers had higher fundamental frequency mode, and lower standard deviation of fundamental frequency compared to bilingual English-Spanish speakers. Bilingual male speakers had higher jitter and harmonics-to-noise ratio than monolingual speakers. On the contrary, female bilingual speakers had lower jitter and shimmer than monolingual speakers.Conclusions. Speaking a second language may influence voice acoustic parameters, and therefore, should be considered when comparing acoustic speech metrics.
