Content-Aware Speaker Recognition

摘要

A content-aware speaker recognition system includes technologies to, among other things, analyze phonetic content of a speech sample, incorporate phonetic content of the speech sample into a speaker model, and use the phonetically-aware speaker model for speaker recognition.

主权项

1. A text-independent speaker recognition system comprising:
a front end module to:
process an audio signal comprising a current sample of natural language speech;identify a speech segment in the current sample of natural language speech; andcreate a phonetic representation of the speech segment of the current speech sample; and a back end module to:
create a current speaker model based on the phonetic representation of the speech segment of the current speech sample, the current speaker model mathematically representing at least one speaker-specific phonemic characteristic of the current speech sample; andcompare the current speaker model to a stored speaker model, the stored speaker model mathematically associating phonetic content with one or more other speech samples.
