Voice-Enabled Push-to-Talk Service for Hands-Free Data Queries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile value-added services, particularly push-to-talk (PTT) technologies, are limited in providing user-friendly data services as they require manual input through screens, which diverts user attention and is not efficient for tasks like navigation or data searches, especially in environments where hands and eyes need to be focused elsewhere.
Innovation Solution
Implementing voice-enabled push-to-talk services on mobile devices with a dedicated button for initiating voice sessions, allowing users to navigate and request data services verbally, leveraging existing PTT infrastructure and integrating with online services like WINDOWS LIVE™ for quick queries and low latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input through screen is used for PTT services, then device complexity is reduced, but user attention is diverted and efficiency is reduced
Solution Approach 1:
The patent replaces manual mechanical input (touching screen, scrolling, typing) with voice-based acoustic input. Users speak commands naturally without looking at or touching the device, substituting the mechanical interaction model with a voice-driven model that keeps eyes and hands on the road.
Solution Approach 2:
The patent introduces voice recognition technology as an intermediary between the user and the PTT service system. Instead of direct manual interaction with the interface, the voice recognition system translates spoken commands into system actions, serving as a mediator that eliminates the need for visual attention during operation.
2Productivity
If voice recognition is implemented for PTT services, then user attention is freed for other tasks, but processing capability and service scope are limited
Solution Approach 1:
The patent makes the voice-enabled PTT button universal by programming it to recognize and execute multiple different commands beyond simple PTT initiation. The same physical button handles navigation requests, information searches, media control, and communication functions, allowing one element to perform many functions.
Solution Approach 2:
The patent implements dynamic functionality where the voice recognition system adapts to different user needs and contexts. The system can interpret various types of commands (navigation, information, media, communication) and adjust its response based on the recognized intent, making the interface flexible rather than fixed.
3Device complexity
If existing PTT infrastructure is leveraged for voice services, then device complexity is minimized, but service functionality remains basic
Solution Approach 1:
The patent enables the existing PTT infrastructure to serve itself by allowing the voice-enabled button to initiate not only traditional PTT calls but also data services, navigation, and information retrieval. The system uses its own communication capabilities to access additional services without requiring separate dedicated hardware for each function.
Data Source
AI summary
Initiation of a search query is accomplished by voice direction, rather than by reading choices and texting or clicking through options. A mobile phone includes a dedicated voice query service button for generating a signal for initiating a voice enabled service session, a speaker and microphone for transducing sounds and electrical signals, a display for displaying visual information to a user, memory for storing data, a transceiver for receiving and transmitting data and a processor. The processor receives a signal generated by the service button for initiating a voice enabled service session, communicates a prompt to a user to begin speaking, stores voice data from a user and transmits the stored voice data to a server for transforming the voice data to a result satisfying the spoken voice service request.
