Voice Playback Information Embedding in Electronic Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for implementing a recording function for electronic signatures require separate storage for voice playback files, which is inconvenient and limits their use in various fields.
Innovation Solution
A method that converts voice playback files into playback information, allowing them to be embedded as header information or bar code images within electronic documents, enabling recognition and playback without the need for separate storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice playback files are stored separately, then voice recording and playback functionality is achieved, but storage complexity and device requirements increase
Solution Approach 1:
The patent merges the voice playback file storage with the electronic document structure by embedding the voice data directly into the document's header information or body content. This integration eliminates the need for separate storage systems, reducing device complexity while maintaining reliable voice recording functionality. The voice data is stored as part of the document structure itself, allowing it to be accessed and played back without requiring external storage resources.
Solution Approach 2:
The electronic document structure is designed to serve multiple functions: it stores both textual information and voice playback files within the same structure. The header information or body content of the document can contain voice data, allowing the document to function as both a text carrier and a voice recording medium simultaneously. This multi-functionality reduces the need for separate specialized storage systems.
2Ease of operation
If voice playback files are embedded in electronic documents, then separate storage is eliminated, but data structure complexity increases
Solution Approach 1:
The patent segments the electronic document into distinct functional areas: header information and body content. Voice playback files can be embedded in either the header or body, creating clearly defined segments with specific purposes. This segmentation provides a systematic approach to data organization, making the structure easier to manage despite the increased functionality. Each segment has a defined role, reducing the operational complexity of working with embedded voice data.
3Measurement precision
If playback information is converted to barcode images, then recognition accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent converts playback information into barcode image representations, creating a visual copy of the data that can be easily recognized and processed. The barcode serves as an accurate representation of the underlying playback information, enabling precise recognition. While the conversion process adds some complexity, the use of standardized barcode formats and automated generation tools minimizes the manufacturing burden, making the process feasible despite the increased steps involved.
Data Source
AI summary
The specification discloses a method of generating and recognizing voice based playback information, and a recording medium for storing instructions for performing the method. That is, a voice playback file for outputting voice is converted to playback information, and the voice is outputted by playing back the voice playback file, when the playback information is recognized. Thus, a recording function, which can be utilized in various fields, can be provided without using a separate storage for storing the voice playback file.
