Smartphones allow good quality recordings; however, it cannot be claimed that the acoustic parameters obtained from them are comparable to those obtained with a professional microphone. The objective of this study is to establish whether there are significant differences when comparing the values of six acoustic parameters obtained from recordings using four smartphones and a professional microphone. The Praat programme was used to obtain the acoustic parameters: f0, Jitter, Shimmer, HNR, Alpha Ratio and L1 - L0 of the recording of a sustained vowel /a/ using iPhone SE, iPhone 6, Samsung S8, Huawei Y7 and the Behringer ECM 8000 microphone. The sample was made up of 26 men and 26 women, from 18 to 26 years old without declared voice pathology. The repeated sample ANOVA test was used to compare the values. All the equipment show reproducibility between consecutive repeated measurements. The parameters f0 and Jitter were the only ones that did not show significant differences between the smartphones and the professional microphone. None of the smartphones studied can replace the professional microphone in voice recording for the evaluation of the six parameters analysed, except for f and Jitter.
智能手机可以进行高质量的录音；然而，我们不能声称从它们获得的声学参数与使用专业麦克风获得的参数可比。本研究的目的是确定使用四部智能手机和一个专业麦克风进行录音时，六个声学参数的测量值是否存在显著差异。使用 Praat 程序获取声学参数：使用 iPhone SE、iPhone 6、Samsung S8、Huawei Y7 和 Behringer ECM 8000 麦克风录制持续元音/a/时的 f0、Jitter、Shimmer、HNR、Alpha Ratio 和 L1-L0。样本由 26 名男性和 26 名女性组成，年龄在 18 至 26 岁之间，无声明的语音病理学。使用重复样本 ANOVA 检验来比较数值。所有设备在连续重复测量之间都表现出可重复性。参数 f0 和 Jitter 是智能手机和专业麦克风之间唯一没有显示出显著差异的参数。在所研究的智能手机中，没有一款可以替代专业麦克风用于评估分析的六个参数，除了 f 和 Jitter。
