Microphone actuation control system suitable for teleconference systems
TLDR
In this paper, a decisional circuitry monitors the microphone signal of the associated microphone with respect to a MAX bus which carries microphone signals representative of the level of microphone signals at the other microphones.Abstract:
A microphone and loudspeaker arrangement for use in a teleconference system, wherein a plurality of microphones are held in a fixed relationship to a loudspeaker. The microphones are independently gated ON in response to (1) speech picked up by the microphone, (2) a loudspeaker signal driving the loudspeaker and (3) an electrical signal related to the microphone signals of the other associated microphones. A noise adapting threshold circuit generates a voltage level representative of background noise which is compared with the microphone signal of a respective microphone for determining whether the microphone is receiving speech. A decisional circuitry monitors the microphone signal of the associated microphone with respect to a MAX bus which carries microphone signals representative of the level of microphone signals at the other microphones. The decisional circuitry generates a signal indicating that the associated microphone is the first loudest microphone signal.read more

Intelligent Automated Assistant
Thomas R. Gruber,Adam Cheyer,Dag Kittlaus,Didier Rene Guzzoni,Christopher Dean Brigham,Richard Donald Giuli,Marcello Bastea-Forte,Harry J. Saddler +7 more
TL;DR: In this article, an intelligent automated assistant system engages with the user in an integrated, conversational manner using natural language dialog, and invokes external services when appropriate to obtain information or perform various actions.
Patent
Using context information to facilitate processing of commands in a virtual assistant
TL;DR: In this article, a virtual assistant uses context information to supplement natural language or gestural input from a user, which helps to clarify the user's intent and reduce the number of candidate interpretations of user's input, and reduces the need for the user to provide excessive clarification input.

Sound actuated microphone system
TL;DR: In this paper, the output signals of each microphone element are converted to D.C. logarithmic signals which are compared for gating an electrical output signal of a microphone element to the output/amplifying system.
Patent
Control apparatus for sound reinforcement systems
TL;DR: In this paper, a control apparatus for a sound reinforcement system having plural audio input program microphones installed in a theater or like environment is described, where the ambient sound or noise level in the environment is sensed and is employed to control each microphone individually so that a microphone is activated only if the audio material impinging thereon exceeds the ambient noise level.

Multimicrophone loudspeaking telephone system
TL;DR: A modified speakerphone conference system with a plurality of microphones employs a comparator in combination with logic circuitry that selects the microphone with the greatest output and connects it to the speakerphone input while simultaneously disconnecting the others as discussed by the authors.
Patent
Directable microphone system
TL;DR: In this article, a plurality of directable beam microphones structures are directed to a prescribed location, and the signals produced in the microphone structures are selectively adjusted to accept sounds from a predetermined volume surrounding the location and to reject sounds outside the prescribed volume.
Patent
Control system for audio amplifying system having multiple microphones
TL;DR: A conference-type audio amplifier system has a plurality of voice-controlled microphones which produce individual output signals as mentioned in this paper, each microphone has an analog switch for turning the microphone on or off in response to its control signal relative to a reference threshold.
