Abstract: A method and a voice processor that includes (i) an input that is configured to receive of audio signals that represent audio, (ii) a wake word detection circuit, (iii) a first buffer that is configured to store at least wake word signals and prebuffer signals, and (iv) a communication module that is configured to (a) output, over an interrupt port, an interrupt request to an application processor, following a detection of the wake word signals, (b) following an acceptance of the application processor to receive content, access the first buffer and retrieve the prebuffer signals and the wake word signals; and (b) output the content, over the I2S port, to the application processor. The content includes the wake word signals, the prebuffer signals, and query or command signals.

Abstract: A method for determining an occupancy of a meeting room, the method may include receiving or determining, by a computerized system, an allocation of the meeting room to a meeting during a time period; checking whether audio feedback regarding an actual usage of the meeting room was received at a beginning of the time period; determining an actual usage of the meeting room based on a reception of the audio feedback or a lack of reception of the audio feedback; and updating a database and multiple user devices regarding the actual usage of the meeting room.
