Assistance Device Speech Name Identification for Non-Verbal Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assistance devices that recognize speech cannot effectively identify care receivers who are unable to speak, limiting their usability.
Innovation Solution
An assistance device equipped with a speech detector and a name acquiring section that identifies care receivers based on names spoken by caregivers, allowing for reliable user identification regardless of the care receiver's ability to speak.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition is used to identify care receivers, then user identification can be performed based on spoken commands, but care receivers who cannot speak cannot use the device
Solution Approach 1:
The patent introduces caregivers as intermediaries who speak on behalf of non-verbal care receivers. The speech recognition system detects names spoken by caregivers, and the control unit identifies the intended care receiver based on these spoken names, enabling non-verbal users to operate the device through third-party assistance
Solution Approach 2:
The system automatically processes the spoken name to identify the care receiver without requiring manual selection or additional input. The control unit extracts the name from the speech signal and automatically retrieves the corresponding user profile, enabling seamless operation
2Measurement precision
If speech-based identification is implemented, then the system can recognize specific care receivers, but the system becomes dependent on the care receiver's ability to speak
Solution Approach 1:
The speech recognition system serves multiple functions: it can identify care receivers who speak directly, and it can also capture names spoken by caregivers on behalf of non-verbal users. This multi-functional approach allows the same system to adapt to different user conditions while maintaining accurate identification
3Reliability
If the system relies on care receivers speaking their own names, then direct user input is obtained, but user identification fails when caregivers change
Solution Approach 1:
By using caregivers as intermediaries who speak the care receiver's name, the system creates a reliable identification method that works regardless of which caregiver is present. The speech recognition captures the name from any caregiver's speech, ensuring consistent user identification across different caregivers
Data Source
AI summary
An assistance device that more appropriately identifies a user using speech. The assistance device is provided with a speech detector, a name acquiring section that acquires a name of a person based on speech detected by the speech detector, and a user identifying section that identifies a care receiver who is a user of the assistance device based on the name acquired by the name acquiring device.
