Audible Message Alert via Challenge Phrase Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile devices often cannot read or listen to messages due to safety concerns or silent mode settings, leading to missed important communications.
Innovation Solution
A mobile device with an audible presentation module that analyzes messages for a predetermined challenge phrase, allowing messages to be played loudly even when the device is in silent mode, ensuring users receive critical messages without distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile device is set to silent mode to prevent distraction, then user privacy and focus are improved, but the user cannot hear important messages
Solution Approach 1:
The system applies different audio output qualities to different messages. Important messages containing the challenge phrase are routed to the loud speaker for audible notification, while other messages maintain silent mode. This local differentiation resolves the contradiction by allowing selective audio output based on message importance.
Solution Approach 2:
The challenge phrase acts as an intermediary mechanism between the silent mode setting and message notification. By embedding the challenge phrase in important messages, the system creates a covert communication channel that bypasses the silent mode restriction, allowing critical information to reach the user without compromising overall privacy.
2Loss of information
If the user holds the phone to their ear to hear messages, then message delivery is improved, but user safety and convenience are worsened
Solution Approach 1:
The system changes the spatial dimension of message delivery by using the loud speaker to project audio outward into the environment, rather than requiring the user to hold the device to their ear. This dimensional shift allows message delivery while the user keeps their hands free and maintains situational awareness.
Solution Approach 2:
The mobile device autonomously detects the challenge phrase and automatically routes the message to the loud speaker without requiring user intervention. The system self-determines which messages require audible notification, eliminating the need for the user to manually hold the device to their ear.
3Loss of information
If all messages are played audibly, then complete information delivery is improved, but user distraction and privacy loss increase
Solution Approach 1:
The system applies selective audio output based on the local characteristics of each message. Messages containing the challenge phrase receive audible notification through the loud speaker, while other messages remain silent. This localized audio treatment ensures complete information delivery for critical messages while maintaining privacy and reducing distraction for non-critical communications.
Solution Approach 2:
Instead of applying audio notification to all messages (excessive action), the system applies it only to messages containing the challenge phrase (partial action). This selective approach provides sufficient information delivery for important messages while avoiding the negative effects of universal audio notification.

AI summary
Methods and apparatus to audibly provide messages an electronic device are described. An example method includes receiving a message at the electronic device, determining that the message includes a predetermined phrase, and in response to determining that the message includes the predetermined phrase, audibly presenting, at the electronic device, an alert that requests an audio input.
