The mismatch negativity component (MMN) of auditory event-related potentials (ERP) was recorded in four aphasic patients and in age, gender and education matched controls. The MMN changes elicited by tone, vowel, voicing stop consonant and place-of articulation contrasts were recorded over both hemispheres. The results of MMN amplitude, latency and(More)
—Many phonetic and phonology domain research papers analyzed segmental duration: what factors and interactions between factors determine their duration. Their results often play an important role in Language Technology applications, for example TTS (text-to-speech synthesis), ASR (automatic speech recognition) widely used in infocommunication. Speech sound(More)
In this paper, a large Hungarian spoken language database is introduced. This phonetically-based multipurpose database contains various types of spontaneous and read speech from 333 monolingual speakers (about 50 minutes of speech sample per speaker). This study presents the background and motivation of the development of the BEA Hungarian database,(More)
Neurolinguistic investigations support the dissociation between speech production and speech perception in the case of aphasia. This means that an aphasic patient may be able to understand words and sentences while he is not able to produce them or, he may be able to produce certain linguistic forms properly while he is not able to detect the semantics of(More)
The purpose of this study is to establish whether there is any connection between neonatal morbidity and speech perception and comprehension in children of pre-school age who have previously been treated as newborn infants in an intensive care unit. The test applied is a method invented in Hungary for the analysis of global hearing, speech perception and(More)
