AURAL SIMILARITY MEASURING SYSTEM FOR TEXT
First Claim
1. An aural similarity measuring system for measuring the aural similarity of texts comprising:
- a text input interface;
a reference text source;
an output interface; and
a processor adapted to convert the input text into a string of phonemes, to adjust the phoneme string of the input text and/or a phoneme string of a reference text so that the two phoneme strings are equal in length, and to assign a score to the reference text representative of the similarity of the two phoneme strings, which score is output via the output interface.

Abstract
The aural similarity measuring system and method provides a measure of the aural similarity between a target text (10) and one or more reference texts (11). Both the target text (10) and the reference texts (11) are converted into a string of phonemes (15) and then one or other of the phoneme strings are adjusted (16) so that both are equal in length. The phoneme strings are compared (12) and a score generated representative of the degree of similarity of the two phoneme strings. Finally, where there is a plurality of reference texts the similarity scores for each of the reference texts are ranked (13). With this aural similarity measuring system the analysis is automated thereby reducing risks of errors and omissions. Moreover, the system provides an objective measure of aural similarity enabling consistency of comparison in results and reproducibility of results.

8. An aural similarity measuring server comprising:
-
an input/output interface adapted for communication with one or more remote user terminals and further adapted to receive an input text and to output one or more reference texts each associated with a similarity score; a data store in which is stored a plurality of reference texts; and a processor adapted to convert an input text into a string of phonemes, to adjust the phoneme string of the input text and/or a phoneme string of a reference text so that the two phoneme strings are equal in length, and to assign a score to the reference text representative of the similarity of the two phoneme strings, which score is output via the input/output interface. - View Dependent Claims (9, 10, 11, 12, 13)

14. A computer readable medium encoded with a computer program having instructions for aural similarity measurement, the computer program comprising program instructions for performing the following steps:
-
a receiving step in which an input text for which an aural similarity score is required is received; a conversion step in which the input text is converted into a string of phonemes; an adjustment step in which the phoneme string for the input text and/or a phoneme string associated with a reference text is adjusted so that the two phoneme strings are equal in length; a ranking step in which the similarity of the two phoneme strings is assigned a score; and an output step in which the reference text and the its ranking is output to the user. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. An aural similarity measuring method for measuring the aural similarity of texts, the method comprising the steps of:
-
receiving an input text for which an aural similarity score is required; converting the input text into a string of phonemes; adjusting the phoneme string for the input text and/or a phoneme string associated with a reference text so that the two phoneme strings are equal in length; ranking the similarity of the two phoneme strings to assign a score; and outputting the reference text and its ranking to the user.
