Abstract
An apparatus for oversampling audio signals is described herein. The apparatus includes one or more microphones to receive audio signals and an extractor to extract a set of feature points from the audio signals. The apparatus also includes a processing unit to determine a distance between each pair of feature points and an oversampling unit to generate a plurality of new feature points based the distance between each pair of feature points.
Claims25
An apparatus, for oversampling audio signals comprising:
- one or more microphones to receive audio signals;
- an extractor to extract a set of feature points from the audio signals;
- a processing unit to determine a distance between each pair of feature points of the set of feature points;
- and
- an oversampling unit to generate a plurality of new feature points based on the distance between each pair of feature points and to generate a speaker voice model.
An method for oversampling audio signals, comprising:
- capturing audio signals from an utterance;
- extracting a set of feature points from the audio signals;
- determining a distance between each pair of feature points of the set of feature points;
- generating a plurality of new feature points based on the distance between each pair of feature points of the set of feature points;
- and
- identifying a user via recognition decisions based on the plurality of new feature points and the set of feature points.
(canceled)
A system for oversampling audio signals comprising, comprising:
- a microphone;
- a memory that is to store instructions and that is communicatively coupled to the microphone;
- and
- a processor communicatively coupled to the microphone and the memory, wherein when the processor is to execute the instructions, the processor is to:
- receive audio signals from an utterance;
- extract a set of feature points from the audio signals;
- determine a distance between each pair of feature points of the set of feature points
- generating a plurality of new feature points based on the distance between each pair of feature points of the set of feature points;
- extrapolate a plurality of feature vectors based on the plurality of new feature points and the set of feature points;
- and
- identify a user via recognition decisions based on the plurality of new feature points, the set of feature points, and the plurality of feature vectors.
A non-transitory computer-readable medium, comprising instructions that, when executed by the processor, direct the processor to
- capture audio signals from an utterance;
- extract a set of feature points from the audio signals;
- determine a distance between each pair of feature points of the set of feature points;
- generate a plurality of new feature points based on the distance between each pair of feature points of the set of feature points;
- and
- identify a user via recognition decisions based on the plurality of new feature points and the set of feature points.
