Mobile Voice-to-Speech Driving Mode With Audible Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-to-speech services are not optimized for users operating vehicles, leading to safety concerns as visual feedback from screens can distract and disrupt driving.
Innovation Solution
A method and mobile terminal implementation that detects vehicle operation and switches to a driving mode, prioritizing audible feedback with increased speed and minimizing visual feedback to enhance user safety while driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual feedback is provided through GUI on the screen, then information delivery is complete and accurate, but user safety deteriorates due to distraction during driving
Solution Approach 1:
The patent replaces the visual display mechanism (GUI on screen) with an acoustic output mechanism (speaker). The text-to-speech conversion system transforms visual information delivery into auditory information delivery, allowing drivers to receive complete information without visual distraction. The controller activates the speaker to output audible feedback instead of relying on screen display.
Solution Approach 2:
The patent changes the output parameter from visual (screen display) to auditory (speaker output). By detecting driving status through sensor information and automatically adjusting the feedback mode, the system transforms how information is presented - converting GUI visual feedback into TTS audible feedback with adjusted playback speed appropriate for driving conditions.
2Object-affected harmful factors
If audible feedback is provided through speaker, then user safety is improved by reducing visual distraction, but information delivery efficiency deteriorates due to longer processing time
Solution Approach 1:
The patent dynamically adjusts the playback speed of audible feedback based on driving status. When driving mode is detected, the system increases the playback speed of text-to-speech output compared to non-driving mode. This dynamic speed adjustment allows complete information to be delivered auditorily in less time, compensating for the generally slower pace of auditory processing.
Solution Approach 2:
The system implements a feedback loop where sensor information about driving status is continuously monitored, and the output mode (visual vs. auditory) and parameters (playback speed) are automatically adjusted in response. This feedback mechanism ensures optimal information delivery timing by adapting to real-time driving conditions.
3Loss of information
If detailed information is provided as GUI feedback, then information completeness is improved, but ease of operation deteriorates due to difficulty in using while driving
Solution Approach 1:
The patent replaces the visual interaction mechanism (GUI requiring screen viewing and manual operation) with an acoustic interaction mechanism (speaker and microphone). Users can receive and interact with detailed information through voice commands and audible feedback without needing to view or manually operate visual interfaces, greatly improving ease of operation during driving.
Solution Approach 2:
The system provides universal information delivery that works equally well whether the user is driving or not. By offering both visual and auditory feedback channels that can function independently, the system ensures complete usability in all conditions - auditory feedback serves as a universal interface that replaces visual interaction when needed.

AI summary
A method of providing a voice to speech service in a mobile terminal and a corresponding mobile terminal are provided. The method includes receiving sensing information from a sensor unit, determining whether to set an operating mode of the voice to speech service as a driving mode according to the sensing information, and providing audible feedback according to pre-stored driving mode setting information when an operating mode of the voice to speech service is set as the driving mode.
