Abstract: An apparatus of a multiagent system comprises a processing unit to process a unit of analysis on sensor data received from a sensor, and to provide a latency estimate to process the unit of analysis, and a decision system coupled with the processing unit to execute a decision process in response to an event, wherein the decision system utilizes the latency estimate as part of the decision process.

Abstract: Apparatuses and methods for selecting, for communicating, between signals provided by various pickups on the basis of a calculated signal to noise ratio (SNR) are disclosed. The various pickups may include a microphone and a vibration sensor. Signals from the microphone may be compared with signals from the vibration sensor by extracting a root-mean-square (RMS) profile for each, and comparing the RMS profiles to determine an SNR estimate for the microphone signal. The microphone signal may be selected if the SNR estimate is below a predetermined threshold, otherwise the vibration sensor signal may be selected. The vibration sensor signal may be subject to further processing if selected to approximate the microphone signal.

Abstract: A system, apparatus, method, and computer program product for a speaking aid. The system including network interface circuitry to receive speech input from a user. The speech input includes a partial sentence with a missing word or the partial sentence with a stuttered word. The system also includes a processor coupled to the network interface circuitry and one or more memory devices coupled to the processor. The one or more memory devices include instructions, that when executed by the processor, cause the system to detect a stutter or pause in the speech input, predict the stuttered word or the missing word, present a predicted word from an n-best list to the user; and if a prompt is received from the user, present a next word from the n-best list until the user speaks a correct word to replace the stutter or the pause.

Abstract: A system, method, apparatus and computer readable medium for hierarchical speech recognition resolution. The method of hierarchical speech recognition resolution on a platform includes receiving a speech stream from a microphone. The speech stream is resolved using a lowest possible level automatic speech recognition (ASR) engine of multi-level ASR engines. The selection of the lowest possible level ASR engine is based on policies defined for the platform. If resolution of the speech stream is rated less than a predetermined confidence level, the resolution of the speech stream is pushed to a next higher-level ASR engine of the multi-level ASR engines until the resolution of the speech stream meets the predetermined confidence level without violating one or more policies.

Abstract: A system, apparatus, method, and computer readable medium for using an audio trigger for surveillance in a security system. The method including receiving an audio input stream via a microphone. Dividing the audio input stream into audio segments. Filtering high energy audio segments from the audio segments. If a high energy audio segment includes speech, then determining if the speech is recognized as the speech of users of the system. If the high energy audio segment does not include the speech, then classifying the high energy audio segment as an interesting sound or an uninteresting sound. Determining whether to turn video on based on classification of the high energy audio segment as the interesting sound, speech recognition of the speech as the speech of the users of the system, and contextual data.
