Multi-Device Voice Response Volume Selection by Command Loudness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In homes with multiple voice-operated user devices, coordinating responses to voice commands and adjusting response volumes becomes cumbersome, as existing systems lack efficient methods to determine which device should respond and at what volume, often leading to user inconvenience.
Innovation Solution
A media guidance application that detects voice commands and determines the response volume based on the voice command's volume level, identifying the nearest device by comparing volume levels across multiple devices and adjusting responses accordingly, while also considering ambient noise and user profiles to ensure optimal audio delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple voice-operated user devices are deployed in a home, then device coverage and accessibility are improved, but coordination complexity and difficulty in determining which device should respond increase
Solution Approach 1:
Each voice-operated user device autonomously determines its own suitability for responding to a voice command by analyzing the volume level of the command it receives. The device compares its received volume level against volume levels received by other devices (or a threshold) and automatically decides whether to respond, eliminating the need for external coordination or user intervention in device selection.
Solution Approach 2:
The system uses the volume level parameter of the voice command as received by different devices to dynamically determine which device should respond. By changing the response behavior based on the volume level parameter, the system resolves the coordination problem among multiple devices without requiring complex communication protocols or centralized control.
2Ease of operation
If response volume is automatically adjusted based on voice command volume, then ease of operation is improved, but reliability of response delivery may worsen when background noise is present
Solution Approach 1:
The system performs preliminary filtering of the voice command signal to remove background noise before determining the volume level. By预先 removing the background noise component from the audio signal, the system ensures that the subsequent volume-based response determination is based on accurate voice command levels rather than contaminated by ambient noise, thus maintaining reliability while enabling automatic volume adjustment.
Solution Approach 2:
The system uses feedback from multiple devices about the volume level they received to determine the appropriate response volume. By aggregating volume level information from multiple sources and using this feedback to adjust the response, the system can compensate for background noise interference and ensure reliable response delivery at an appropriate volume level.
3Measurement precision
If manual device selection and volume setting are required, then response accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The voice-operated user device automatically performs both device selection and volume setting based on the volume level of the received voice command. The device determines its own suitability for responding and automatically configures the appropriate response volume, eliminating the need for manual user intervention while maintaining accurate response delivery based on the voice command's characteristics.

AI summary
Systems and methods are provided herein for responding to a voice command at a volume level based on a volume level of the voice command. For example, a media guidance application may detect, through a first voice-operated user device of a plurality of voice- operated user devices, a voice command spoken by a user. The media guidance application may determine a first volume level of the voice command. Based on the volume level of the voice command, the media guidance application may determine that a second voice-operated user device of the plurality of voice-operated user devices is closer to the user than any of the other voice-operated user devices. The media guidance application may generate an audible response, through the second voice-operated user device, at a second volume level that is set based on the first volume level of the voice command.
