Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for processing and analyzing audio communications in law enforcement and call centers are labor-intensive, time-consuming, and ineffective, making it difficult to efficiently connect information across different days or individuals.
Innovation Solution
A system and method that converts audio data from voice calls into searchable text transcripts, storing the data in a database for efficient retrieval and analysis, allowing for user interface searches and automatic alerts based on keywords or metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual transcription and review of audio calls is used, then information can be accessed, but the process is labor intensive and time consuming
Solution Approach 1:
The patent replaces manual mechanical transcription processes with automated speech-to-text conversion systems. Audio calls are automatically converted to text transcripts using computer-based speech recognition technology, eliminating the need for human transcribers to manually write down spoken words. This substitution dramatically reduces both the time required and labor costs while maintaining transcription accuracy.
Solution Approach 2:
The system enables self-service by allowing users to automatically search and retrieve information from transcribed calls without requiring manual intervention. The searchable database automatically indexes transcribed text, enabling users to query and access call information independently through keyword searches, thus eliminating the need for manual information retrieval processes.
2Loss of information
If manual review of individual transcripts is used, then information can be connected, but the process is expensive and ineffective
Solution Approach 1:
The patent implements a universal searchable database system that handles multiple types of queries and search criteria simultaneously. The same database infrastructure supports searches by keyword, speaker, time period, call type, and other parameters, allowing diverse information retrieval needs to be met through a single unified system rather than multiple separate manual review processes.
Solution Approach 2:
The patent introduces an automated speech-to-text conversion system as an intermediary between audio calls and human analysts. This intermediary automatically transcribes and indexes call content, serving as a bridge that transforms unstructured audio data into structured, searchable text data without requiring direct human intervention in the transcription process.
3Speed
If searchable database indexing is implemented, then quick access to audio data is enabled, but automated processing requires significant resources
Solution Approach 1:
The patent applies preliminary action by automatically transcribing and indexing audio call data immediately upon receipt, rather than waiting for manual processing. The speech-to-text system converts audio to text and the database system creates searchable indexes in advance, so that when users need to retrieve information, the data is already prepared and readily accessible, eliminating delays.
Solution Approach 2:
The patent creates text copies of audio call data through automated speech-to-text conversion. Instead of requiring users to listen to original audio recordings, the system generates accurate text transcripts that can be searched and retrieved efficiently. These text copies serve as lightweight surrogates that are much faster to process and search than the original audio files.
Data Source
AI summary
The present invention discloses a system, apparatus, and method that obtains audio and metadata information from voice calls, generates textual transcripts from those calls, and makes the resulting data searchable via a user interface. The system converts audio data from one or more sources (such as a telecommunications provider) into searchable usable text transcripts. One use of which is law enforcement and intelligence work. Another use relates to call centers to improve quality and track customer service history. Searches can be performed for callers, callees, keywords, and/or other information in calls across the system. The system can also generate automatic alerts based on callers, callees, keywords, phone numbers, and/or other information. Further the system generates and provides analytic information on the use of the phone system, the semantic content of the calls, and the connections between callers and phone numbers called, which can aid analysts in detecting patterns of behavior, and in looking for patterns of equipment use or failure.
