Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for speaker verification. The methods, systems, and apparatus include actions of inputting speech data that corresponds to a particular utterance to a first neural network and determining an evaluation vector based on output at a hidden layer of the first neural network. Additional actions include obtaining a reference vector that corresponds to a past utterance of a particular speaker. Further actions include inputting the evaluation vector and the reference vector to a second neural network that is trained on a set of labeled pairs of feature vectors to identify whether speakers associated with the labeled pairs of feature vectors are the same speaker. More actions include determining, based on an output of the second neural network, whether the particular utterance was likely spoken by the particular speaker.

Abstract: Systems, methods, and computer-readable media are provided for performing actions in response to gestures made by a user in captured images. In accordance with one implementation, a computer-implemented system is provided that includes an image capture device that captures at least one image, a memory device that stores instructions, and at least one processor that executes the instructions stored in the memory device. In some implementations, the processor receives, from the image capture device, at least one image including a gesture made by a user and analyzes the at least one image to identify the gesture made by the user. In some implementations, the processor also determines, based on the identified gesture, one or more actions to perform on the at least one image.

Abstract: This specification describes, among other things, a computer-implemented method. The method can include receiving a stream of audio data at a computing device. The stream of audio data can be segmented into a plurality of audio segments. Respective intensity levels are determined for each of the plurality of audio segments. For each of the plurality of audio segments and based on the respective intensity levels, a determination can be made as to whether the audio segment includes a speech signal. Selective gain control can be performed on the stream of audio data by automatically adjusting a gain of particular ones of the plurality of audio segments that are determined to include a speech signal.
