Abstract
Phonetic distances are empirically measured as a function of speech recognition engine recognition error rates. The error rates are determined by comparing a recognized speech file with a reference file. The phonetic distances can be normalized to earlier measurements. The phonetic distances/error rates can also be used to improve speech recognition engine grammar selection, as an aid in language training and evaluation, and in other applications.
Claims17
A method of generating a phonetic distance matrix comprising:
- determining a plurality of error occurrences by comparing a recognized speech file with a reference file;
- determining a plurality of error rates corresponding to the plurality of error occurrences;
- determining a plurality of phonetic distances as a function of the plurality of error rates;
- and
- outputting a phonetic distance matrix based on the plurality of phonetic distances.
