Latest Patents
Cumani's latest patents include a method and apparatus for efficient i-vector extraction. This innovation addresses the complexities associated with typical i-vector extraction procedures, which are often demanding in terms of computations and memory usage. His 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, Cumani's approach significantly reduces memory usage and enhances execution speed.
Another notable patent is for 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. By efficiently representing these uncertainties, Cumani's technique allows for improved memory usage and computation, ultimately leading to a more accurate assessment of whether two speech samples belong to the same speaker.
