摘要
目的探讨国产智能手机录音用于测试基频(F0)的可能性及潜在影响因素。方法38例成年女性朗读一句话(语料2)以及持续发元音/a/(语料1),用两种智能手机(华为G7 Plus和Vivo X6)和Praat软件进行录音,测试F0,两种智能手机分别被随机放置在三个角度(0°、45°和90°)和四个距离(距离口唇5、10、15、20 cm),而用Praat录音的Shure-SV100C动态麦克风保持在45°和距离口唇15厘米以获得标准参考数据;将智能手机测得的F0与Praat测得的标准参考数据相比较。结果智能手机的放置位置和语音材料对F0无显著影响,设备、语料、距离和角度的主效应均不显著(P>0.05),而智能手机的类型却有明显不同,两种测试语料Vivo手机和Praat测得的F0差异均有统计学意义(对于/a:/,P=0.014<0.05;对于句子,P=0.028<0.05),而华为G7 Plus与Praat测得的F0差异无统计学意义(P>0.05)。结论国产智能手机(华为G7 Plus和Vivo X6)可用于F0的测试,手机的放置位置和语音材料对F0测试结果无显著影响,但使用华为G7 Plus手机进行F0测试时,录音距离和角度分别为5~20 cm和0°~90°。
Objective To study the possibility and potential influencing factors of using smartphone recording to test F0.Methods Thirty eight adult women read a sentence(corpus 2)and pronounced the sustained vowel/a/(corpus 1)which were recorded with two kinds of smart phones(Huawei G7 plus and vivo x6)and Praat software to test F0.Two kinds of smart phones were randomly placed at three angles(0°,45°and 90°)and four distances(5,10,15 and 20 cm away from the lip),while the Shure-SV100C dynamic microphone recorded by Praat was kept at 45°and 15 cm away from the lip to obtain standard reference data.The F0 measured by smartphone was compared with the standard reference data measured by Praat.Results The location of smart phones and speech materials had no significant effect on F0.The main effects of recording device,corpus,distance and angle were not significant(P>0.05),while the types of smart phones were significantly different.There were significant differences in F0 between vivo and Praat(for/a:/,P=0.014<0.05;for sentences,P=0.028<0.05),but there was no significant difference in F0 between Huawei mobile phone and Praat(P>0.05).Conclusion Whether it is Huawei G7 plus or vivo X6,the location of smart phones and voice materials have no significant effect on F0 test results.However,not all types of mobile phones are suitable.When using Huawei G7 plus mobile phones to test F0,the recording distance and angle are 5~20 cm and 0°~90°respectively.
