Three experiments examine the effect of a difference in fundamental frequency (F0) range between two simultaneous voices on the processing of unattended speech. Previous experiments have only found evidence for the processing of nominally unattended speech when it has consisted of isolated words which could have attracted the listener's attention. A… (More)
Studies that have dealt with the effect of sound spectral and temporal properties on environmental sound identification have focused on a narrow range of sounds [1, 2, 3]. The purpose of the research was to evaluate the effect of sound temporal characteristics on the identification of 72 different environmental sounds, 29 of them having a rhythmic… (More)
This study assessed the influence of tempo on selecting a sound sequence. In Exp. 1, synchronization with one of the two regular subsequences in a complex sequence was measured. 30 participants indicated a preference for the fastest subsequence when subsequences were in a slow tempo range (> or = 500 msec. IOI), and with the slower subsequence when they… (More)
Rivenez et al. [J. Acoust. Soc. Am. 119 (6), 4027-4040 (2006)] recently demonstrated that an unattended message is able to prime by 28 ms a simultaneously presented attended message when the two messages have a different F0 range. This study asks whether a difference in vocal-tract length between the two messages rather than a difference in F0 can also… (More)
(Expérience 2 et 4) et de timbre (Expérience 3 et 4) entre les messages co-occurrents sur le traitement du message non focalisé.
This study addresses the question of speech processing under unattended conditions. Dupoux et al. (2003) have recently claimed that unattended words are not lexically processed. We test their conclusion with a different paradigm : participants had to detect a target word belonging to a specific category presented in a rapid list of words, in the attended… (More)
