Abstract
A method and device for recognizing dialectal variations in a language. From an incoming speech is on one hand a speech recognition procedure being performed, and on the other hand the fundamental tone curve being extracted. Out of the speech recognition is created an allophone string which together with the fundamental tone curve is used for the detecting of the maximun and minimum values of the fundamental tone. The recognized speech is compared with a lexicon with orthography and transcription for the finding of suitable word candidates. The found word candidates are further analyzed regarding syntax. This in mentioned way found syntactical and lexical information is used for creating a model of the speech. The fundamental tone outline of the model and the fundamental tone of the speech are compared, at which the maximun and minimum values of the fundamental tones are appointed and a difference between the model and the speech are obtained. The difference is after that influencing the model which is brought to correspond to the given speech. The in mentioned way modelled model is then used for the speech recognition, at which an increased possibility to understand the different …
