Reassembling speech sentence fragments using associated phonetic property
First Claim
1. A method of composing messages for speech output consisting of segments (10) of at least one original sentence, which are stored as audio files, in which a message intended for output is composed from the segments (10) stored as audio files, selected using search criteria from the stored audio files,characterised in that each segment (10) is allocated at least one parameter (12) characterising its phonetic properties in the original sentence and using the parameters (12) of the individual segments (10) characterising the phonetic properties in the original sentence a check is made as to whether the segments (10) forming the reproduction sentence to be output as a message are composed according to their natural flow of speech.

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.
