Audio Navigation Speed Control on Standard Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio navigation techniques are inefficient for users with standard phones, as they struggle to skim through audio content quickly and maintain continuity due to sequential inputs disrupting the control flow, and existing methods fail to provide effective speed control and marker placement for convenient navigation.
Innovation Solution
The system allows users to receive audio browsing commands over a telephone channel, saving application state and re-synthesizing audio to alter playback speed, and enabling marker placement for convenient navigation, using speed control processing techniques that analyze user interactions to generate new audio files with adjusted speeds and maintain prosody, while utilizing client-server architecture to facilitate efficient audio navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users provide sequential navigation inputs over telephone/audio channel, then audio content can be accessed on standard phones, but the continuity of audio content is disrupted
Solution Approach 1:
The system pre-generates multiple speed versions of audio content (e.g., 0.5x, 0.75x, 1.0x, 1.25x, 1.5x playback speeds) before user interaction. When users provide navigation inputs, the system can immediately switch between pre-generated speed versions without disrupting audio continuity, as the transitions occur between pre-prepared segments rather than requiring real-time processing during playback.
2Productivity
If audio playback speed is altered to enable skimming, then navigation efficiency is improved, but audio quality and prosody may be degraded
Solution Approach 1:
The system changes the playback speed parameter of audio content by generating multiple versions with different speed factors (0.5x, 0.75x, 1.0x, 1.25x, 1.5x). Each speed version is pre-generated with adjusted temporal parameters while maintaining the original audio quality characteristics. This allows users to select appropriate playback speeds for different navigation needs without degrading the fundamental audio quality, as each speed version preserves the original prosody and articulation patterns within acceptable ranges.
3Ease of operation
If markers are placed to enable quick navigation, then user convenience is improved, but system complexity increases
Solution Approach 1:
The system automatically generates and manages audio markers without requiring manual intervention. Markers are placed at semantically significant points in the audio content based on automatic analysis of the audio stream, such as detecting topic transitions, key information points, or natural segmentation boundaries. This self-service approach provides convenient navigation markers to users while minimizing the need for complex manual configuration or intervention, as the system autonomously performs marker placement based on predefined criteria.

AI summary
Systems and associated methods configured to provide user-driven audio content navigation for the spoken web are described. Embodiments allow users to skim audio for content that seems to be of relevance to the user, similar to visual skimming of standard web pages, and mark point of interest within the audio. Embodiments provide techniques for navigating audio content while interacting with information systems in a client-server environment, where the client device can be a simple, standard telephone.
