Abstract

This disclosure provides systems, methods, and apparatus associated with an electrostatically driven graphene speaker. In one aspect, a device includes a graphene membrane, a first frame on a first side of the graphene membrane, and a second frame on a second side of the graphene membrane. The first frame and the second frame both include substantially circular open regions that define a substantially circular portion of the graphene membrane. A first electrode is proximate the first side of the circular portion of the graphene membrane. A second electrode proximate the second side of the circular portion of the graphene membrane.

Electrostatic force assisted deposition of graphene

Patent Liang, Xiaogan [Berkeley, CA]

An embodiment of a method of depositing graphene includes bringing a stamp into contact with a substrate over a contact area. The stamp has at least a few layers of the graphene covering the contact area. An electric field is developed over the contact area. The stamp is removed from the vicinity of the substrate which leaves at least a layer of the graphene substantially covering the contact area.

Joint speaker authentication and key phrase identification

Patent McLaren, Mitchell Leigh; Lawson, Aaron Dennis

A spoken command analyzer computing system includes technologies configured to analyze information extracted from a speech sample and, using a joint speaker and phonetic content model, both determine whether the analyzed speech includes certain content (e.g., a command) and to identify the identity of the human speaker of the speech. In response to determining that the identity matches the authorized user's identity and determining that the analyzed speech includes the modeled content (e.g., command), an action corresponding to the verified content (e.g., command) is performed by an associated device.

Speaker verification system using acoustic data and non-acoustic data

Patent Gable, Todd J [Walnut Creek, CA]; Ng, Lawrence C [Danville, CA]; Holzrichter, John F [Berkeley, CA]; ...

A method and system for speech characterization. One embodiment includes a method for speaker verification which includes collecting data from a speaker, wherein the data comprises acoustic data and non-acoustic data. The data is used to generate a template that includes a first set of "template" parameters. The method further includes receiving a real-time identity claim from a claimant, and using acoustic data and non-acoustic data from the identity claim to generate a second set of parameters. The method further includes comparing the first set of parameters to the set of parameters to determine whether the claimant is the speaker.more »« less
