Abstract (en)
[origin: WO0131434A2] The invention relates to a method for detecting the time sequences of a fundamental frequency of an audio-response unit to be synthesised. The invention is characterised in that input macro segments of the fundamental frequency are detected by means of a neuronal network and are reproduced by means of fundamental frequency sequences that are stored in a data base. According to the inventive method, the fundamental frequency is produced based on a greater text section which is analysed by means of the neuronal network. Microstructures are transferred from the data base to the fundamental frequency. The thus produced fundamental frequency is optimised in the macro and microstructure thereof. An extremely natural sound is thus obtained.
