On automatic cross-lingual subtitle timing
Autor: Karel Blavka, Michal Rott, Marek Bohac
Publikováno v: 2015 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM).
In the last years automatic speech recognition (ASR) technologies are applied as assistant technologies for hearing-impaired people. ASR technologies typically produce some kind of subtitles by two ways: i) directly by the automatic speech recognitio

Iterative grapheme-to-phoneme alignment for the training of WFST-based phonetic conversion
Autor: Marek Bohac, Jiri Malek, Karel Blavka
Publikováno v: TSP
In this paper we propose an algorithm for grapheme-to-phoneme (G2P) alignment. Such alignment is needed mainly for the data-driven training of G2P conversion tools. Our approach utilizes a given phonetic alphabet and a set of given orthographic-phone
