Une méthode statistique pour le contrôle des changements vocaliques sous l’effet du style de parole. Applications à l’espagnol

It is well known that the speech signal conditions of emission can result in influences on the speaker, leading to dramatic changes on her or his speech productions. However, most of the studies performed on the <i>speaking styles</i> restrict their observations on very contrasted situations and compare the so-called <i>spontaneous</i> speech (collected during an ordinary conversation) to the <i>laboratory</i> speech (produced without any communication intention). In this paper, Spanish productions of a single speaker were analysed. Three situations with gradual involvement of the speaker in the communication process have been studied by means of a new methodology for the assessment of the system’s degree of organization in each speaking style, as initiated by previous analysis of Frenchspeaking subjects.
