Comparaison de parole journalistique et de parole spontanée : analyses de séquences entre pauses (Comparison of journalistic and spontaneous speech: analysis of sequences between pauses) [in French]

________________________________________________________________________________________________________ Comparison of journalistic and spontaneous speech: analysis of sequences between pauses. In this study we compare the ESTER corpus of journalistic speech (Galliano et al., 2005) and the NCCF corpus of spontaneous speech (Torreira et al, 2010) in terms of duration, f0 and spectral reduction in productions automatically detected as sequences between, pauses. Continuation f0 rises are overall absent in spontaneous speech and sequences reveal a declination slope with less amplitude than in journalistic speech. For both corpora, lengthening starts around 60% of the sequence duration, but significantly less in spontaneous speech. Lengthening in the initial part of the sequence is observed in journalistic speech only. As expected we measure a faster speech rate in spontaneous speech with shorter vowel durations implying a more important vowel reduction.
