Solution Overview

Problem

Voice output devices struggle to properly recognize and respond to user voices due to noise within the device, distance from the speaker, and surrounding noise, leading to ineffective delivery of responses.

Innovation Solution

An intelligent voice output method that selects an appropriate response device based on recognition state information, determines spoken distance and noise levels, and adjusts response intensity using microphone detection signals and noise information, leveraging a 5G wireless communication system for noise modeling and device state integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a voice output device uses a preset voice for control, then the device can respond to user commands, but the voice recognition accuracy deteriorates due to noise within the device, distance from speaker, or surrounding noise

Engineering Contradiction:
Improveresponse delivery effectivenessVSAvoidvoice recognition accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system uses feedback from multiple voice output devices to determine recognition state information. Each device provides feedback on its ability to recognize the preset voice, and this feedback is used to select the most appropriate device for response delivery, thereby resolving the contradiction between response effectiveness and recognition accuracy

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Multiple voice output devices are employed, each capable of both issuing preset voices and receiving recognition state information. This multi-functionality allows the system to simultaneously perform control operations and evaluate recognition conditions across different devices, selecting the optimal device for each interaction

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the voice output device operates in noisy environments or at distances from the speaker, then the device can maintain operational functionality, but the voice recognition reliability deteriorates

Engineering Contradiction:
Improveoperational functionality in various conditionsVSAvoidvoice recognition reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system obtains recognition state information from multiple devices to assess their performance under different environmental conditions. This feedback mechanism enables the system to identify which devices maintain reliability in noisy or distant conditions and select them for response delivery

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically selects the appropriate voice output device based on real-time recognition state information. This dynamic adaptation allows the system to maintain reliability by choosing devices that are currently in optimal conditions, rather than relying on a fixed preset device

Inventive Principle:
Principle #15Dynamics
