Abstract: Techniques for automatically triggering video surveillance using embedded voice, speech, or sound recognition are provided. In one embodiment, a computer system can receive an audio signal captured from an area to be monitored via video surveillance. The computer system can further recognize, via an embedded recognition component, a voice, speech phrase, or environmental sound in the audio signal, and can determine that the recognized voice, speech phrase, or environmental sound corresponds to a predefined trigger condition. The computer system can then automatically transmit a signal to one or more video capture devices to begin video recording of the area.

Abstract: Systems, methods, and devices for location-based context driven voice recognition are disclosed. A mobile or stationary computing device can include position locating functionality for determining the particular physical location of the computing device. Once the physical location of the computing device determined, a context related to that particular physical location. The context related to the particular physical location can include information regarding objects or experiences a user might encounter while in that particular physical location. The context can then be used to determine delimited or constrained voice recognition vocabulary subset based on the range of experiences a user might encounter within a particular context. The voice recognition vocabulary subset can then be referenced or used by a voice recognizer to increase the speed, accuracy, and effectiveness in receiving, recognizing, and acting in response to voice commands received by the user while in that particular physical location.

Abstract: A client/server text-to-speech synthesis system and method divides the method optimally between client and server. The server stores large databases for pronunciation analysis, prosody generation, and acoustic unit selection corresponding to a normalized text, while the client performs computationally intensive decompression and concatenation of selected acoustic units to generate speech. The units are transmitted from the client to the server in a highly compressed format, with a compression method selected based on the predetermined set of potential acoustic units. This compression method allows for very high-quality and natural-sounding speech to be output at the client machine.
