Voice Mail Speech-to-Text Conversion Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice mail systems lack the ability to efficiently convert and utilize stored speech messages for flexible retrieval and integration into other systems, particularly in multilingual environments, leading to inaccessible information.
Innovation Solution
Incorporating a speech-to-text conversion module to convert speech messages into text format, with optional language translation and text-to-speech conversion for compatibility and user accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If speech messages are stored in voice mail system, then message storage capability is improved, but information accessibility and usability deteriorate
Solution Approach 1:
A speech-to-text conversion module is introduced as an intermediary between the recorder and message storage. This module automatically converts spoken messages into text format, enabling the system to store both audio and text representations of messages. The text format serves as an intermediary representation that makes message content searchable, editable, and integratable with other information systems while preserving the original audio recording.
Solution Approach 2:
The system changes the parameter of message representation from purely audio format to include text format through automatic speech-to-text conversion. This parameter change transforms the physical state of stored information, making it accessible in multiple formats (audio playback and text display/editing) and enabling various processing operations that were not possible with audio alone.
2Adaptability or versatility
If speech messages are stored in standardized format, then system compatibility is improved, but information flexibility for editing and integration deteriorates
Solution Approach 1:
The message storage is segmented into two distinct formats: audio format for faithful reproduction of the original speech and text format for easy editing and integration. The speech-to-text conversion module creates a parallel text representation that can be independently manipulated, allowing users to edit message content, search for keywords, and integrate information with other text-based systems while the original audio recording remains preserved.
3Ease of operation
If speech-to-text conversion module is added, then message accessibility is improved, but device complexity increases
Solution Approach 1:
The speech-to-text conversion module operates automatically without requiring user intervention. When a message is recorded, the system automatically initiates the speech-to-text conversion process, selects appropriate language models, and stores the converted text alongside the audio recording. This self-service approach eliminates the need for manual transcription services while providing comprehensive message accessibility in both audio and text formats.
4Adaptability or versatility
If language translation is implemented, then multilingual accessibility is improved, but processing time increases
Solution Approach 1:
The system performs preliminary speech-to-text conversion immediately when the message is recorded, creating a text representation in the original language. Translation into other languages can then be performed on this pre-converted text rather than on the original audio, significantly reducing processing time. The text-based translation is computationally less intensive than audio processing and can be performed asynchronously or on-demand without blocking the primary message storage function.

AI summary
A method for operating a voice mail system connected to a telecommunication system, having a recorder with a message storage connected thereto, shall enable a particularly flexible use of a speech message stored in the voice mail system. For this purpose, according to the invention, a speech message collected by the recorder, storable as a speech information in the message storage is converted by means of a speech-to-text conversion module into a text message.
