Abstract

A method of composing messages for speech output and the improvement of the quality of reproduction of speech outputs. A series of original sentences for messages is segmented and stored as audio files with search criteria. The length, position, and transition values for the respective segments can be recorded and stored. A sentence to be reproduced is transmitted in a format corresponding to the format of the search criteria. It is determined whether the sentence to be reproduced can be fully reproduced by one segment or a succession of stored segments. The segments found in each case are examined using their entries as to how far the individual segments match as regards speech rhythm. The audio files of the segments in which the examination resulted in the pre-requisites for optimal maintaining of the natural speech rhythm are combined and output for reproduction.
