Speech Recognition Apparatus Visual Timing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users unfamiliar with speech recognition apparatuses struggle to recognize the timing for inputting commands due to difficulty in visually distinguishing prohibition and permission messages amidst a list of available speech options, leading to potential misinterpretation of intended actions.
Innovation Solution
The apparatus displays distinct prohibition and permission messages using different fonts, colors, and imagery alongside the speech list, ensuring users can easily identify when to input commands by clearly indicating whether speech is allowed or prohibited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a list of speeches is displayed on the screen, then users can see available commands, but users unfamiliar with the apparatus cannot easily recognize the timing for inputting commands
Solution Approach 1:
The patent applies color changes by displaying prohibition messages in red and permission messages in green. This color-coding system allows users to quickly and intuitively understand whether speech input is currently allowed or prohibited, resolving the contradiction between providing timing information and making it easy to recognize. The visual distinction through color enables novice users to grasp speech timing rules without confusion.
2Loss of information
If prohibition and permission messages are displayed on the screen, then users can understand speech timing, but the messages are difficult to visually distinguish from the speech list
Solution Approach 1:
The patent applies local quality by making prohibition and permission messages visually distinct from the speech list through different font styles, colors, and positioning. The prohibition message uses red color and specific font characteristics, while permission messages use green, creating local visual qualities that differentiate these elements. This ensures users can easily detect and distinguish timing information from the command list.
Solution Approach 2:
The patent uses color changes with red for prohibition and green for permission messages, creating strong visual contrast against the speech list. This color-coding system enhances detectability and ensures users can quickly identify speech timing status without confusion, directly addressing the difficulty of visually distinguishing different message types.
3Reliability
If the apparatus waits for preparation and initialization processes, then speech recognition can be performed accurately, but the response time is delayed
Solution Approach 1:
The patent applies feedback by displaying real-time visual indicators (prohibition and permission messages) that inform users of the current speech recognition state. This feedback mechanism allows users to understand when the system is preparing and when it is ready, managing expectations during the time delay while maintaining accurate speech recognition through proper initialization processes.

AI summary
Provided are an audio recognition device, a display method, and a display processing program capable of easily recognizing a timing when a user utters even while looking at a list of words which can be uttered. During a period from the moment when an utterance button is pressed by a user until start of an audio recognition processing by an audio recognition unit (114), a system control unit (116) displays an utterance inhibition message (2a) indicating an utterance inhibition at a position arranged in the same column as an utterance list (1) and displays an utterance inhibition mark (3) at the position overlapped with the utterance list (1). After an audio recognition process is started by the audio recognition unit (114), the utterance inhibition message (2a) and the utterance inhibition mark (3) are erased from the screen.
