Latest Patents
One of Laface's latest patents is titled "Method and apparatus for efficient i-vector extraction." This invention addresses the complexities associated with typical i-vector extraction procedures, which are often demanding in terms of computations and memory usage. The method involves determining a representation for each component of a variability operator, which captures the statistical inter- and intra-speaker variability of voice features. By employing a linear operator common to all components, Laface's approach significantly reduces memory usage and potentially increases execution speed.
Another notable patent is "Fast speaker recognition scoring using I-vector posteriors and probabilistic linear discriminant analysis." This method estimates the uncertainties of acoustic coverage for speech utterances by different speakers. It allows for efficient memory usage by discarding dependencies between different sounds, thus streamlining the computation process. The resulting score indicates the likelihood that the speakers are the same individual, enhancing the reliability of speaker recognition systems.
