We have called upon a...

Prussian Blue nanoparticles were electrodeposited on transparent grapheme film, which showed a promising electrochromism with response times in the range of 3.3-38 s.

Phonetic alignment is the task of finding limits phones and higher units in an audio file. This has been reliably done many languages such as English, French German, but, so far, no available Brazilian Portuguese aligner had a performance comparable with ones used for these other languages. Thus, main goal this work was to implement useful tool forced Portuguese. The implementation two steps, g...

Information retrieval from spoken audio has attracted the attention of a number of research groups, in part driven by the recent NIST Spoken Term Detection (STD) evaluation. A common approach is to split the task into two stages. In the first, a large vocabulary continuous speech recognition (LVCSR) system is used to generate a word or phone lattice corresponding to the audio, and in the second...
