Automated Assistant Media Trigger Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple automated assistant devices, unintended activations can occur due to audio data from digital media being processed by one device triggering hotword detection in other nearby devices, leading to negative user experiences and resource wastage.
Innovation Solution
A system that detects and suppresses triggers in audio segments of digital media likely to activate nearby automated assistant devices by identifying active capabilities of nearby devices and modifying the media to prevent unintended activations, using techniques such as inserting digital watermarks or adjusting audio segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hotword detection is performed continuously by multiple automated assistant devices in an environment, then the ability to respond to user commands is improved, but unintended activations from digital media audio segments increase
Solution Approach 1:
The system performs preliminary detection of hotwords in digital media audio segments before playback occurs. By analyzing the media content in advance and identifying segments that contain hotwords or similar-sounding phrases, the system can suppress or modify these segments during playback to prevent unintended activations of automated assistants in the environment.
2Productivity
If audio data from digital media is processed by automated assistants, then the assistants can respond to commands, but computational resources are wasted on unintended activations
Solution Approach 1:
The system performs preliminary analysis of digital media audio segments to identify those containing hotwords before they are played back. By detecting and suppressing these problematic segments in advance, the system prevents wasted computational resources from being consumed by unintended hotword detection and processing operations.
Solution Approach 2:
The system applies preliminary anti-action by suppressing or modifying audio segments that contain hotwords before they can trigger unintended automated assistant activations. This preventive measure counteracts the potential harmful effect of resource wastage by blocking the problematic audio data from reaching the automated assistants' processing systems.
3Adaptability or versatility
If multiple automated assistant devices are deployed in close proximity, then service coverage is improved, but cross-triggering from digital media increases
Solution Approach 1:
The system performs preliminary detection of hotwords in digital media before playback, enabling it to suppress or modify audio segments that would otherwise trigger cross-triggering between multiple automated assistant devices. This allows multiple devices to coexist in close proximity without causing unintended activations.

AI summary
Techniques are described herein for detecting and suppressing commands in media that may trigger another automated assistant. A method includes: determining, for each of a plurality of automated assistant devices in an environment that are each executing at least one automated assistant, an active capability of the automated assistant device; initiating playback of digital media by an automated assistant; in response to initiating playback, processing the digital media to identify an audio segment in the digital media that, upon playback, is expected to trigger activation of at least one automated assistant executing on at least one of the plurality of automated assistant devices in the environment, based on the active capability of the at least one of the plurality of automated assistant devices; and in response to identifying the audio segment in the digital media, modifying the digital media to suppress the activation of the at least one automated assistant.
