Abstract: In one embodiment, a method receives an acoustic input signal at a speech recognizer configured to recognize the acoustic input signal in an always on mode. A set of responses based on the recognized acoustic input signal is determined and ranked based on criteria. A computing device determines if the response should be output based on a ranking of the response. The method determines an output method in a plurality of output methods based on the ranking of the response and outputs the response using the output method if it is determined the response should be output.

Abstract: In one embodiment, a method includes receiving an acoustic input signal at a speech recognizer. A user is identified that is speaking based on the acoustic input signal. The method then determines speaker-specific information previously stored for the user and a set of responses based on the recognized acoustic input signal and the speaker-specific information for the user. It is determined if the response should be output and the response is outputted if it is determined the response should be output.

Abstract: Embodiments of the present invention are directed toward systems, methods and devices for improving information access to and device control in a home automation environment. Functionality of multiple household device, such as lights, sound, entertainment, HVAC, and communication devices can be activated via voice commands. The voice commands are detected by a nearby control device and relayed via a network communication medium to another control device to which the desired device or system that the user wants to operate is connected. Each control device, disposed throughout the home, can detect a voice command intended for another control box and household device and relay the voice command to the intended control box. In such systems, a user can initiate a telephone call by saying a voice command to a local control box that will forward on the control signal to a mobile phone connected to another control box.

In one embodiment, the present invention includes a method comprising receiving a spoken utterance, processing the spoken utterance in a speech recognizer to generate a recognition result, determining consistencies of one or more parameters of component sounds of the spoken utterance, wherein the parameters are selected from the group consisting of duration, energy, and pitch, and wherein each component sound of the spoken utterance has a corresponding value of said parameter, and validating the recognition result based on the consistency of at least one of said parameters.

Abstract: In one embodiment, a computer system stores speech data for a plurality of speakers, where the speech data includes a plurality of feature vectors and, for each feature vector, an associated sub-phonetic class. The computer system then builds, based on the speech data, an artificial neural network (ANN) for modeling speech of a target speaker in the plurality of speakers, where the ANN is configured to discriminate between instances of sub-phonetic classes uttered by the target speaker and instances of sub-phonetic classes uttered by other speakers in the plurality of speakers.

Abstract: In one embodiment the present invention includes a method comprising receiving an acoustic input signal and processing the acoustic input signal with a plurality of acoustic recognition processes configured to recognize the same target sound. Different acoustic recognition processes start processing different segments of the acoustic input signal at different time points in the acoustic input signal. In one embodiment, initial states in the recognition processes may be configured on each time step.

Abstract: Embodiments of the present invention improve content manipulation systems and methods using speech recognition. In one embodiment, the present invention includes a method comprising configuring a recognizer to recognize utterances in the presence of a background audio signal having particular audio characteristics. A composite signal comprising a first audio signal and a spoken utterance of a user is received by the recognizer, where the first audio signal comprises the particular audio characteristics used to configure the recognizer so that the recognizer is desensitized to the first audio signal. The spoke utterance is recognized in the presence of the first audio signal when the spoken utterance is one of the predetermined utterances. An operation is performed on the first audio signal.

Abstract: Systems and methods for improving the interaction between a user and a small electronic device such as a Bluetooth headset are described. The use of a voice user interface in electronic devices may be used. In one embodiment, recognition processing limitations of some devices are overcome by employing speech synthesizers and recognizers in series where one electronic device responds to simple audio commands and sends audio requests to a remote device with more significant recognition analysis capability. Embodiments of the present invention may include systems and methods for utilizing speech recognizers and synthesizers in series to provide simple, reliable, and hands-free interfaces with users.

Abstract: In one embodiment, a method determines an event at a mobile device and a movement value for a speed of movement of the mobile device based on the event.
