Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Correctional facilities face challenges in monitoring communications for potential illicit activities or provocations, as existing methods lack effective detection of significant volume level changes that may indicate such events during inmate communications.
Innovation Solution
A system and method utilizing a computer system to analyze audio communications for significant volume level changes, creating a flag for detected changes, and storing this information in a database to facilitate monitoring and investigation, which can include alerting authorized personnel and terminating communications if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio communications are monitored in controlled-environment facilities, then security and investigative capabilities are improved, but the complexity of detection systems increases
Solution Approach 1:
The patent applies parameter changes by monitoring volume level parameters in audio communications to detect significant changes that may indicate illicit activities or provocations. The system analyzes audio volume parameters over time and triggers alerts when predefined thresholds are exceeded, enabling effective monitoring without requiring complex analysis of all audio content.
2Measurement precision
If significant volume level changes are detected to identify potential illicit activities, then measurement precision is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system focuses on detecting changes in the volume level parameter rather than analyzing the complete audio signal. By monitoring parameter changes (volume increases or decreases beyond predefined thresholds) and comparing them against baseline values, the system achieves precise detection of significant events while avoiding the complexity of comprehensive audio content analysis.

AI summary
Systems and methods for detecting volume level changes in communications are described herein. In some embodiments, a system comprises a computer system. The computer system comprises at least one processor and a memory coupled to the at least one processor. The memory stores program instructions that are executable by the at least one processor to cause the computer system to perform tasks. The tasks include recording a communication that comprises audio, and analyzing the audio of the communication. The analysis of the audio is operable to detect a change in a volume level of the audio that indicates an occurrence of a potential event of interest. The tasks also include creating and storing an information record corresponding to the communication in a second database. The information record includes an indication of the detected change in the volume level.
