In a voice transformation context, prosody transformation using parallel corpora is quite unrealistic as such corpora are difficult and also expensive to build. Based on this observation, we propose an approach for transforming prosody using non-parallel corpora thanks to the MLLR adaptation strategy. This methodology is applied to the joint transformation(More)
This article is interested in the problem of the linguistic content of a speech corpus. Depending on the target task, the phonological and linguistic content of the corpus is controlled by collecting a set of sentences which covers a preset description of phonological attributes under the constraint of an overall duration as small as possible. This goal is(More)
This article describes a new approach to estimate F 0 curves using a B-Spline model characterized by a knot sequence and associated control points. The free parameters of the model are the number of knots and their location. The free-knot placement , which is a NP-hard problem, is done using a global MLE within a simulated-annealing strategy. The optimal(More)
This article is interestedin the problem of the linguisticcon-tent of a speech corpus. Depending on the target task (speech recognition, speech synthesis, etc) we try to control the phono-logical and linguistic content of the corpus by collecting an optimal set of sentences which make it possible to cover a pre-set description of phonological attributes(More)
