简要总结
Like many other animals, humans produce nonverbal vocal signals including screams, grunts, roars, cries and laughter across a variety of contexts. However, despite their importance in the human vocal repertoire, the mechanisms and functions of non-verbal signals remain little studied and poorly understood in humans.Our studies aim to improve our understanding of the nature and function of non-verbal signals.
详细描述
Like many other animals, humans produce nonverbal vocal signals including screams, grunts, roars, cries and laughter across a variety of contexts. Many of these signals (such as cries) are already produced at birth and likely serve a number of important biological and social functions. In addition, human speech is characterised by nonlinguistic acoustic parameters (such as pitch, formant frequencies, and nonlinear phenomena) that are known to correlate with biologically important traits of the vocalizer.
However, despite their importance in the human vocal repertoire, the mechanisms and functions of non-verbal signals remain little studied and poorly understood in humans.
Theses studies aim to improve the understanding of the nature and function of non-verbal signals. Thus, this study is part of a long-term research project in which investigators are trying to clarify the information contained in the acoustic structure of human non-verbal signals, and to investigate the factors influencing their production.

研究组 & 干预措施
Healthy adult population aged 18 to 80 years
Participants will be asked to produce vocal sounds of different nature according to the non-verbal parameters of interest for the given study.
干预措施: Production of vocal sounds (Behavioral)
结局指标
主要结局
Vocal analysis
时间窗: During the vocal production
Participants will receive instructions on what to say or what type of non-verbal vocalisation to produce during the manipulation. The vocalisations thus produced by the participants will be systematically recorded and analysed using software adapted to acoustic analysis Measurement of acoustic variables such as fundamental frequency (pitch), vocal tract resonances (formants) and vocal disturbances (jitter, shimmer), the nonlinearities and chaotic/noise properties of vocalisations
次要结局
- Skin conductance (Siemens)(During the vocal production)
- Heart rate (bpm)(During the vocal production)
- Skin temperature (°C)(During the vocal production)
- Nociception Level Index (NOL)(During the vocal production)
- Pupillary diameter (millimeter)(During the vocal production)
