Captioning Device Message Playback Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing-impaired users face difficulties in understanding voice messages stored locally on captioning devices, as the beginning portion of the message is often missed during captioning due to delayed connection establishment with remote call assistants, leading to incomplete captioning.
Innovation Solution
Implementing a method to automatically delay the playback of voice messages on captioning devices until a connection is established with a remote call assistant, ensuring real-time captioning from the beginning of playback, or until a specific time period expires, to prevent prolonged delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If voice message playback is delayed until connection with remote call assistant is established, then captioning completeness is improved, but playback delay increases
Solution Approach 1:
The system establishes the connection with the remote call assistant before initiating voice message playback. This preliminary action ensures that the captioning service is ready to provide real-time captions from the beginning of the message, preventing any loss of information at the start of the playback.
Solution Approach 2:
The system dynamically adjusts the playback timing based on the connection establishment status. It implements a flexible delay mechanism that adapts to network conditions and service availability, balancing the need for complete captioning with the user's expectation for timely playback.
2Reliability
If connection establishment time is extended, then captioning quality is improved, but user waiting time increases
Solution Approach 1:
The system performs connection establishment and service initialization before the user actually needs to play the message. By preparing the captioning service in advance, it ensures high-quality reliable captioning is ready without requiring the user to wait during playback.
Solution Approach 2:
The system automatically manages the connection establishment process with the remote call assistant without requiring user intervention. It handles the timing and coordination autonomously, ensuring captioning quality while minimizing perceived user waiting time.
3Measurement precision
If real-time captioning is implemented from message beginning, then information accuracy is improved, but system complexity increases
Solution Approach 1:
The system introduces a remote call assistant as an intermediary service that handles the real-time captioning processing. This external service absorbs the complexity of real-time speech-to-text conversion, allowing the local captioning device to maintain simplicity while still achieving accurate real-time captioning from the message beginning.
Solution Approach 2:
The system establishes the connection with the remote call assistant and prepares the captioning infrastructure before playback begins. This preliminary setup ensures that when playback starts, the real-time captioning is already operational and ready to provide accurate information from the very beginning of the message.

AI summary
A method for automatically delaying playback of a message at a captioning device may include obtaining, at the captioning device, a request to playback of the message. The method may also include, in response to the request, automatically delaying the playback of the message at the captioning device in order to allow the captioning system to receive the audio of the message from a beginning of the playback of the audio of the message.
