METHOD FOR DETECTING THE TIME SEQUENCES OF A FUNDAMENTAL FREQUENCY OF AN AUDIO-RESPONSE UNIT TO BE SYNTHESISED

摘要

Predetermined macrosegments of the fundamental frequency are determined by a neural network, and these predefined macrosegments are reproduced by fundamental-frequency sequences stored in a database. The fundamental frequency is generated on the basis of a relatively large text section which is analyzed by the neural network. Microstructures from the database are received in the fundamental frequency. The fundamental frequency thus formed is thus optimized both with regard to its macrostructure and to its microstructure. As a result, an extremely natural sound is achieved.
