Speech Lighting Control with State-Based Recognition Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speech recognition systems for controlling light fixtures are prone to errors, leading to incorrect state changes of light fixtures.
Innovation Solution
A lighting control system that includes a speech recognition unit, a lighting control unit, a state decision unit, and a condition setting unit, which performs speech recognition, controls light fixtures based on recognized commands, and adjusts recognition conditions based on the state of the light fixture to reduce errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition is used to control light fixtures, then ease of operation is improved, but speech recognition errors cause incorrect state changes
Solution Approach 1:
The system displays the recognized speech and intended state change to the user before execution. This feedback mechanism allows users to verify recognition accuracy and correct errors, resolving the contradiction by maintaining ease of operation while improving reliability through user confirmation
Solution Approach 2:
The system performs preliminary speech recognition and displays the recognized content before actually changing the light fixture state. This preliminary action allows error detection and correction before execution, ensuring reliable operation while maintaining user-friendly speech control
2Ease of operation
If speech recognition sensitivity is increased to capture more commands, then ease of operation is improved, but false activations increase
Solution Approach 1:
The system provides feedback by displaying recognized speech and intended actions before execution. This allows users to identify and correct false activations, maintaining high sensitivity for ease of operation while eliminating harmful false activations through user verification
Solution Approach 2:
The system takes preliminary action by displaying and confirming recognized commands before execution. This prevents false activations from causing harmful effects while maintaining the sensitivity needed for easy operation, as users can block incorrect commands before they execute
Data Source
AI summary
A microphone picks up a speech and outputs a speech signal. A lighting control unit recognizes the speech by performing speech recognition on the speech signal, thereby generating command data corresponding to the speech recognized. The lighting control unit controls a light fixture based on the command data. A state decision unit makes a state decision of the light fixture. A condition setting unit sets, depending on the state decision made by the state decision unit, a condition for a speech recognition unit to perform the speech recognition.
