Vehicle Audio Interaction for Hands-Free Lyrics and Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in vehicles often experience boredom during long journeys due to the lack of engaging audio entertainment options, particularly when drivers cannot safely access song lyrics or control audio playback.
Innovation Solution
An interactive audio entertainment system that includes an audio playback module, recognition module, and text-to-speech module, allowing users to interact with audio streams through voice commands, identify lyric information, and switch between instrumental and vocal tracks, with feedback via speakers and haptic elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all players have access to lyrics and playback controls, then entertainment quality is improved, but device complexity and safety risks increase for drivers
Solution Approach 1:
The patent segments the user interface into multiple interaction modes: voice commands for drivers (safe interaction) and traditional touchscreen/physical controls for passengers (full access). The system divides functionality so that drivers can request lyrics and control playback through natural speech, while passengers retain access to visual displays and manual controls, thereby reducing the complexity burden on the driver interface while maintaining comprehensive system capabilities.
Solution Approach 2:
The patent introduces a voice recognition intermediary that translates driver intent into system commands without requiring direct interaction with complex control interfaces. The voice interface acts as a mediator between the driver and the audio system, converting natural language requests into structured commands for playback control and lyric display, thereby simplifying the driver's interaction while maintaining full system functionality.
2Ease of operation
If drivers access lyrics through traditional interfaces, then lyric access is improved, but safety deteriorates due to distraction
Solution Approach 1:
The patent replaces mechanical/touch-based interaction interfaces with voice-based acoustic interaction for driver lyric access. Instead of requiring drivers to touch screens or manipulate physical controls to view lyrics, the system enables drivers to request and receive lyric information through voice commands, substituting the mechanical interaction paradigm with acoustic speech recognition, thereby eliminating the distraction associated with visual and manual engagement.
Solution Approach 2:
The system enables drivers to independently access lyrics and control playback through natural voice commands without requiring visual attention or manual operation. The voice interface allows drivers to self-serve by requesting lyrics, pausing playback, or adjusting volume through speech, making the interaction intuitive and hands-free, thereby eliminating safety risks while maintaining ease of operation.
3Ease of operation
If voice control is implemented, then ease of operation is improved, but measurement precision of user intent deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system confirms voice commands to the driver, allowing for clarification or correction of recognized intents. The voice recognition system provides auditory feedback about what it has understood, enabling the driver to confirm or rephrase commands, thereby improving the precision of command recognition while maintaining the ease of voice-based interaction.
Data Source
AI summary
A system for interacting with an audio stream to obtain lyric information, control playback of the audio stream, and control aspects of the audio stream. In some instances, end users can request that the audio stream play with a lead vocal track or without a lead vocal track. Obtaining lyric information includes receiving via a text to speech module an audio playback of the lyric information.
