Latest Patents

One of her latest patents is titled "Multiple pitch extraction by strength calculation from extrema." This innovative apparatus includes a function module, a strength module, and a filter module. The function module compares an input signal, which has a component, to a first delayed version of the input signal and a second delayed version of the input signal to produce a multi-dimensional model. The strength module calculates the strength of each extremum from a plurality of extrema of the multi-dimensional model based on a value of at least one opposite extremum of the multi-dimensional model. It identifies a first extremum associated with a pitch of the component of the input signal, which has a strength greater than the remaining extrema. The filter module then extracts the pitch of the component from the input signal based on the strength of the first extremum.

Another notable patent is "Systems and methods for speech extraction." In this invention, a processor-readable medium stores code representing instructions to cause a processor to receive an input signal having a first component and a second component. An estimate of the first component of the input signal is calculated based on an estimate of a pitch of the first component. The estimate of the input signal is then calculated based on the estimates of both components. The estimate of the first component is modified based on a scaling function to produce a reconstructed first component of the input signal.
