Library and toolkit ROOTS
ROOTS, standing for Rich Object Oriented Transcription System, is a C++ library dedicated to annotated sequential data management, usually speech or text. Beside C++, a complete Perl binding has been developed.
The library is coming along with scripts and wrappers enabling quick basic operations on a speech signal (ranging from linguistic to acoustic). ROOTS can be used in combination with standard tools like Transcriber and Wavesurfer, widely used in the speech community.
Unit selection synthesis engine
A speech sythesis engine based on a unit selection algorithm with possibilities to propose and test new cost functions.
Optimal building of corpora using Lagrangian relaxation and a greedy algorithm.
Listening test platform
HTML5 Web platform to conduct subjective listening tests with most popular evaluation standards.
Grumph is a grapheme-to-phoneme converter based on conditional random fields (CRFs) and weighted finite state transducers (WFSTs). Grumph generates probabilistic phoneme lattices. See [Lecorve2015] for more details.
Sequential Data Mining under Constraints (SDMC)
SDMC provides a set of tools for sequential data mining. SDMC has been developped in conjunction with the GREYC, MODYCO and LIPN institutes, using our sequential pattern mining algorithms.
