Advances in Large Vocabulary Continuous Speech Recognition in Greek: Modeling and nonlinear features
Rodomagoulakis, I.; Potamianos, G.; Maragos, P. (2013)The main goal of this work is the development of an improved Large Vocabulary Continuous Speech Recognition (LVCSR) framework in Greek. Language modeling is carried out in a collection of journalistic text and in the ... -
The Athena-RC system for speech activity detection and speaker localization in the DIRHA smart home
Giannoulis, P.; Tsiami, A.; Rodomagoulakis, I.; Katsamanis, A.; Potamianos, G.; Maragos, P. (2014)We present our system for speech activity detection and speaker localization inside a smart home with multiple rooms equipped with microphone arrays of known geometry and placement. The smart home is developed as part of ... -
ATHENA: A Greek multi-sensory database for home automation control
Tsiami, A.; Rodomagoulakis, I.; Giannoulis, P.; Katsamanis, A.; Potamianos, G.; Maragos, P. (2014)In this paper we present a Greek speech database with real multi-modal data in a smart home two-room environment. In total, 20 speakers were recorded in 240 one-minute long sessions. The recordings include utterances of ... -
Experiments on far-field multichannel speech processing in smart homes
Rodomagoulakis, I.; Giannoulis, P.; Skordilis, Z. I.; Maragos, P.; Potamianos, G. (2013)In this paper, we examine three problems that rise in the modern, challenging area of far-field speech processing. The developed methods for each problem, namely (a) multichannel speech enhancement, (b) voice activity ... -
Robust far-field spoken command recognition for home automation combining adaptation and multichannel processing
Katsamanis, A.; Rodomagoulakis, I.; Potamianos, G.; Maragos, P.; Tsiami, A. (2014)The paper presents our approach to speech-controlled home automation. We are focusing on the detection and recognition of spoken commands preceded by a key-phrase as recorded in a voice-enabled apartment by a set of multiple ...
