OBJECTIVES/HYPOTHESIS: Voice imitation of a famous personality results in detection and reproduction of some vocal features, including spectral characteristics but also prosody, speech flow, or articulatory patterns. The objective of this study was to describe vocal flexibility in one of the best French impersonators and determine his strategies.
Prospective study.
We have downloaded the recording of a political speech by former French President Jacques Chirac, who we have chosen for his very specific and recognizable voice. After transcription, we asked one professional impersonator and four control subjects to do several readings in their natural voice and in a spontaneous imitation task (ie, without listening to any of Chirac's recording). To facilitate the control subject's task, we made an additional recording after having them listen to the target sample. Using Praat freeware, we have compared several prosodic measurements taken on each sample: pitch, pitch range, articulatory speed, duration of pauses, and number of pauses.
Results showed significant modifications in the participant's prosody and significant differences in the strategies used by the professional impersonator and the control group.
The professional impersonator's imitation strategy lies in the reproduction of global characteristics and instant alignment of prosodic variations.
目的/假设：模仿名人的声音会导致对某些声音特征的检测和再现，包括频谱特征，但也包括韵律、语音流或发音模式。本研究的目的是描述一位最佳法国模仿者之一的声音灵活性，并确定他的策略。
前瞻性研究。
我们下载了法国前总统雅克·希拉克（Jacques Chirac）的一段政治演讲录音，我们选择他是因为他的声音非常特别且易于辨认。转录后，我们请一位专业模仿者和四位对照组受试者用自然声音和自发模仿任务（即不听任何希拉克的录音）进行多次朗读。为了方便对照组受试者的任务，我们在让他们听目标样本后进行了额外的录音。我们使用 Praat 免费软件比较了每个样本的几个韵律测量值：音高、音高范围、发音速度、停顿持续时间和停顿次数。
结果显示，参与者的韵律发生了显著变化，专业模仿者和对照组使用的策略也存在显著差异。
专业模仿者的模仿策略在于对整体特征的再现和韵律变化的即时调整。
