Voice Output Apparatus Text Voice Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice output apparatuses that transmit information via both voice and text messages often fail to effectively capture user attention, as the user's focus is primarily on the voice message, rendering the text message ineffective in conveying information due to the time required to process and focus on it.
Innovation Solution
A voice output apparatus that incorporates a delay mechanism, estimating the time necessary for a user to visually identify and focus on a text message, and then outputs the corresponding voice message after this delay, ensuring simultaneous recognition and attention to both text and voice messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the voice output apparatus outputs both voice message and text message simultaneously, then the information transmission redundancy is improved, but the user's attention to the text message deteriorates because the user focuses on the voice message
Solution Approach 1:
The patent applies preliminary action by displaying the text message before outputting the voice message. The text message is presented to the user first, allowing the user to read and process the visual information while the voice message is being prepared. This sequencing ensures that the user's attention is naturally directed to the text message initially, improving the effectiveness of text-based information transmission while maintaining the redundancy benefit of dual-channel output.
2Productivity
If the text message is displayed for a short duration, then the information transmission efficiency is improved, but the user cannot visually identify the text message within the available time
Solution Approach 1:
The patent applies dynamics by making the text message display duration variable rather than fixed. The display duration is dynamically adjusted based on the estimated time required for the user to visually identify and process the text message. This dynamic timing ensures that the text message remains on screen long enough for the user to read it completely, while not displaying it excessively long, thus balancing information transmission efficiency with user identification accuracy.
3Speed
If the voice message is output immediately after text display, then the response speed is improved, but the user cannot process both text and voice information effectively
Solution Approach 1:
The patent applies preliminary action by having the text message displayed before the voice message is output. This sequencing allows the user to first process the visual information at their own pace, then transition to processing the auditory information. The voice message is output after the text display begins, creating an overlapping period where the user can read the text while anticipating or processing the voice message, thereby ensuring complete information processing without sacrificing overall response speed.

AI summary
A voice output apparatus, enhancing a robustness of an interface between a user and the apparatus by transmitting, information to the user via text message and voice message. The voice output apparatus including a display unit (107) displaying a text message that is apparatus-transmitting information to be transmitted to the user, a delay unit (105), and a voice output unit (106) estimating a delay time necessary for an action taken by the user to visually identify the text message displayed by the display unit (107), and outputting, via voice message, the apparatus-transmitting information, when the delay time (T) passes after the text message is displayed.
