SYSTEMS AND METHODS FOR AVOIDING INADVERTENTLY TRIGGERING A VOICE ASSISTANT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282308 titled 'SYSTEMS AND METHODS FOR AVOIDING INADVERTENTLY TRIGGERING A VOICE ASSISTANT
- Simplified Explanation:**
This patent application describes a system and method to prevent accidental activation of a voice assistant by audio played through a speaker. By analyzing the quality of captured audio signals, the system can determine if the audio is from a pre-recorded source and avoid triggering the voice assistant.
- Key Features and Innovation:**
- Capturing audio signals at a higher sampling frequency than expected to detect artifacts from compression or approximation.
- Calculating a quality metric of the captured audio to determine if it is pre-recorded.
- Preventing the voice assistant from being activated if the audio is identified as pre-recorded.
- Potential Applications:**
This technology can be used in smart speakers, home automation systems, and other devices with voice assistants to improve user experience and prevent unintended activations.
- Problems Solved:**
The technology addresses the issue of voice assistants being triggered by background audio, leading to unwanted responses or actions.
- Benefits:**
- Enhanced user privacy by avoiding accidental voice assistant activations.
- Improved user experience with more accurate voice assistant responses.
- Prevents disruptions caused by unintended voice assistant interactions.
- Commercial Applications:**
- Title: "Advanced Audio Detection System for Voice Assistants"
- This technology can be integrated into smart home devices, automotive systems, and consumer electronics to provide a more reliable and user-friendly voice assistant experience.
- Market Implications: Increased demand for smart devices with enhanced voice control capabilities.
- Prior Art:**
Research into audio signal processing, voice recognition technology, and smart speaker systems may provide insights into similar methods or systems.
- Frequently Updated Research:**
Stay informed about advancements in audio signal processing, voice assistant technology, and privacy features in smart devices.
- Questions about Voice Assistant Activation Prevention:**
1. How does the system differentiate between live audio and pre-recorded audio? 2. What are the potential challenges in implementing this technology across different types of devices?
Original Abstract Submitted
systems and methods are provided herein for avoiding inadvertently trigging a voice assistant with audio played through a speaker. an audio signal is captured by sampling a microphone of the voice assistant at a sampling frequency that is higher than an expected finite sampling frequency of previously recorded audio played through the speaker to generate a voice data sample. a quality metric of the generated voice data sample is calculated by determining whether the generated voice data sample comprises artifacts resulting from previous compression or approximation by the expected finite sampling frequency. based on the calculated quality metric, it is determined whether the captured audio signal is previously recorded audio played through the speaker. responsive to the determination that the captured audio signal is previously recorded audio played through the speaker, the voice assistant refrains from being activated.
