The paper is focussed on the vocalic differences between spontaneous and laboratory speech in Spanish. The first and second formants of 954 vowel utterances (477 in laboratory and 477 in spontaneous speech) have been measured. They constitute clusters in the F1/F2 space. The paper describes inter- and intra-cluster variabilities caused by communication situations changes. In spontaneous speech, the formants values show (1) a marked schwa-tendency; (2) increasing intra-cluster variability. Both phenomena result in lowered differenciation of the sounds in spontaneous speech. © 1992.
