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 providing access to a plurality of reference texts;
a processor adapted toa) convert an input text into a string of phonemes,b) to adjust the phoneme string of the input text and a phoneme string of a reference text from said reference text source so that the two phoneme strings are equal in length,c) to assign a similarity score to the reference text representative of the similarity of the two phoneme strings, andd) to repeat steps b) and c) for at least one further reference text from said reference text source; and
an output interface adapted to output a plurality of reference texts to which similarity scores have been assigned and their respective assigned similarity scores.

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.

23. A computer readable medium encoded with a computer program for execution on a computer or server comprising at least one processor to cause the computer or server to perform an aural similarity measuring method, 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 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 similarity score; a repeating step in which the adjustment step and the ranking step are repeated for further reference texts; and an output step in which a plurality of reference texts to which similarity scores have been assigned and their assigned similarity scores are output to the user. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
