NOISE CANCELLATION FOR OPEN MICROPHONE MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240312454 titled 'NOISE CANCELLATION FOR OPEN MICROPHONE MODE
Simplified Explanation:
The patent application describes a system where multiple audio-enabled devices communicate with each other using an open microphone mode. When a user says a trigger word, the nearest device validates it and opens a communication channel with another device. The device analyzes the audio signal to detect when the user stops talking, transitioning from transmission to reception mode.
- Key Features and Innovation:
- Multiple audio-enabled devices communicating over open microphone mode - Trigger word activation for communication between devices - Continuous analysis of audio signal to detect user speech - Transition from transmission to reception mode based on user speech patterns
Potential Applications: This technology can be used in various applications such as smart home devices, conference call systems, and voice-controlled assistants.
Problems Solved: - Efficient communication between audio-enabled devices - Seamless transition between transmission and reception modes - Accurate detection of user speech patterns
Benefits: - Improved user experience with seamless communication - Enhanced efficiency in audio-enabled device interactions - Better control and management of audio signals in conversations
Commercial Applications: Potential commercial applications include smart home automation systems, conference call solutions, and voice-controlled devices for various industries.
Prior Art: Readers can explore prior art related to audio signal processing, speech recognition technologies, and communication systems for further research.
Frequently Updated Research: Stay updated on advancements in audio signal processing, speech recognition algorithms, and communication protocols relevant to this technology.
Questions about the Technology: 1. How does the system differentiate between user speech and background noise? 2. What measures are in place to ensure data security and privacy in the communication process?
Original Abstract Submitted
a system has multiple audio-enabled devices that communicate with one another over an open microphone mode of communication. when a user says a trigger word, the nearest device validates the trigger word and opens a communication channel with another device. as the user talks, the device receives the speech and generates an audio signal representation that includes the user speech and may additionally include other background or interfering sound from the environment. the device transmits the audio signal to the other device as part of a conversation, while continually analyzing the audio signal to detect when the user stops talking. this analysis may include watching for a lack of speech in the audio signal for a period of time, or an abrupt change in context of the speech (indicating the speech is from another source), or canceling noise or other interfering sound to isolate whether the user is still speaking. once the device confirms that the user has stopped talking, the device transitions from a transmission mode to a reception mode to await a reply in the conversation.
