    Rhythm in reading aloud: artificial and natural voice
    2015, Vol.XX-2, pp. 63-77

    This paper compares the rhythmic features obtained in natural and in synthesized speech along three dimensions: the speech type (synthesized vs natural speech), the literary genre (rhymes, poems vs story telling), and the communication setting (speech addressed to children vs addressed to adults). The study is based on the analysis of duration patterns observed in a corpus recorded by two speakers and generated by a synthesis system. Results show that rhythmic differences between synthesized and natural speech are mostly due to the marking of prosodic structure by duration.This work is achieved within a project aiming at improving the naturalness of synthesized speech for use in pedagogical software.

    French ‘liaison’ in casually spoken French, as investigated in a large corpus of casual French speech
    2012, Vol. XVII-1, pp. 113-128

    In this paper, the realisation of the French Liaison is investigated in a large corpus of casual speech. Considering that casual speech gives rise to a large range of pronunciation variants and that overall temporal reduction increases, one may hypothesize that French liaison tends to be less productive in this speaking style. We made use of automatic processing such as automatic speech alignments to evaluate when liaison is realized in the NCCFr corpus. Realized liaisons were examined and measured for the most frequent liaison consonants (/z/, /n/ and /t/) as a function of a liaison sites classified as mandatory, optional or forbidden. The relation between speech rate and liaison realization is also examined.
