The purpose of this work was the development of a set of tools to automate the process of multilevel annotation of speech signals, preserving the alignments of the utterance's different levels of the linguistic representation. Our goal is to build speech databases, using speech from non professional speakers with multilevel relational annotations, that can(More)
The emerging new applications of synthetic characters, as a way to achieve more natural interactions, puts new demands on the synthetic voices, in order to fulfill the expectations of the user. The work presented in this paper evaluates a synthetic voice used by a synthetic character in a storytelling situation. To allow for a better comparison, a real(More)
This paper describes the INESC-ID participation in the Blizzard Challenge 2008, which consisted in building the two English voices. We have been developing a new European Portuguese TTS system, called DIXI, for the last two years. This year, the system was already stable enough to be used in the challenge, after a partial adaptation to support synthesis in(More)
A co-design strategy for the implementation of a low-voltage fully integrated CMOS receiver is presented. This co-design approach allows the design of a compact direct-conversion receiver by avoiding 50 Ω matching buffers and networks, and AC coupling capacitors between mixer inputs and LNA and oscillator outputs. Moreover, the proposed circuit does(More)
Background. Peritoneal membrane changes are induced by uraemia per se. We hypothesise that previous renal replacement therapy (RRT) time and residual renal function (RRF) at start of peritoneal dialysis impact on ultrafiltration failure (UFF). Methods. The time course of PET parameters from 123 incident patients, followed for median 26 (4–105) months, was(More)
