Obesity and overweight are big healthcare challenges in the world's population. Automatic food intake recognition algorithms based on analysis of food intake sounds offer the potential of being a useful tool for simplifying data logging of consumed food. High inter-individual differences of the users' food intake sounds decrease the classification accuracy(More)
In this paper a method for speech quality evaluation of TTS system is presented and its usability is assessed. The ITU-T P.563 is used as a reference-free objective measurement method for speech sequences synthesized by concatenative TTS system. The method was examined and the achieved results were compared to those measured by subjective auditory tests and(More)
This paper deals with basic principles for projecting and building of speech synthesizer for Macedonian language, based on concatenation of speech segments. The structure of general speech synthesis system is described and there are details about the specific features of Macedonian language important for the speech synthesis, like sound and vowel system and(More)
This paper presents a method that combines variable frame length and rate analysis for speech recognition in noisy environments, together with an investigation of the effect of different frame lengths on speech recognition performance. The method adopts frame selection using an a posteriori signal-to-noise (SNR) ratio weighted energy distance and increases(More)
This paper presents a cross-language development method for speech recognition and synthesis applications for Macedonian language. Unified system for speech recognition and synthesis trained on German language data was used for acoustic model bootstrapping and adaptation. Both knowledge-based and data-driven approaches for source and target language phoneme(More)
In this paper a method for speech quality estimation was evaluated by simulating transfer of speech over packet switched and mobile networks. The proposed system uses Dynamic Time Warping algorithm for test and received speech comparison. Several tests have been made on test speech sample of single speaker with simulated packet (frame) loss effects on the(More)
Glottal stops are sounds produced by the closing and abrupt opening of the vocal folds. In German, glottal stops are frequent before word-initial vowels and are a salient word-linking technique. For this reason, German speakers can transfer this word-linking habit to their English productions. Neither in English nor in German are glottal stops phonemes,(More)
This paper deals with the acknowledgements for data modeling of the educational content objects according to SCORM specifications and their use in additional educational functionalities, like e-testing systems. There is also a description of a prototype of learning management system which manages educational content objects according to the described data(More)
