Two-minute spontaneous conversational speech of English and Cantonese was obtained from 86 Cantonese-English bilingual children. As a physical measurement of the rate of vocal fold vibration during speech production, fundamental frequency (F0) characteristics including the mean speaking F0, pitch sigma, minimum and maximum F0 values were measured from the medial 60-second portion of the speech samples by using Praat. F0 data measured from the English and Cantonese productions were statistically compared. Significant correlation was found for speaking F0, pitch sigma, and F0 range values between Cantonese and English. Results indicated that speaking F0 and F0 range values were significantly lower in Cantonese than in English. It is speculated that such difference is related to the tonal nature of Cantonese, although language proficiency may play a role in the discrepant F0 findings.
从86名粤英双语儿童中获取了两分钟的英语和粤语自发对话语音。作为语音产生过程中声带振动速率的一项物理测量，通过使用Praat软件，从语音样本中间的60秒部分测量了包括平均说话基频、音高标准差、最低和最高基频值在内的基频（F0）特征。对从英语和粤语语音中测量得到的F0数据进行了统计学比较。结果发现，粤语和英语之间在说话基频、音高标准差和F0范围值方面存在显著相关性。结果表明，粤语的说话基频和F0范围值显著低于英语。据推测，这种差异与粤语的声调性质有关，尽管语言熟练度可能在F0结果的差异中也起到了一定作用。
