How we harnessed AI for audio evidence review





In the high-stakes environment of a criminal trial, a large organization found themselves in need of expert assistance to handle a massive volume of voice recordings and intercepts, amounting to up to 25,000 hours. The task involved not just transcribing this enormous dataset but also reviewing it meticulously to aid in the legal proceedings. The complexity of the task was further amplified by the initial state of the source data, which was messy and devoid of any relevant metadata, posing a significant challenge in terms of processing and review.


The primary challenge was to coordinate a process that spanned from decryption of the source material to its transcription and eventual integration into the eDiscovery solution, RelativityOne. The sheer volume of the data, coupled with its disorganized state, necessitated the deployment of advanced technological solutions to ensure accuracy and efficiency in processing the data for the review team. The task at hand was not just labor-intensive but required a high degree of expertise to filter and categorize the data effectively, setting the stage for a successful review by the counsel.


Our solution was a coordinated effort that leveraged cutting-edge technology and expert oversight at every stage. The methodology involved:

  1. Decryption and Preliminary Review: The first step was to decrypt the source material, followed by a preliminary review to understand the scope and nature of the data involved.
  2. Integration with RelativityOne: Following decryption, the data was processed and integrated into the eDiscovery solution, RelativityOne, setting a structured pathway for detailed analysis.
  3. Utilization of Artificial Intelligence: Our partners employed artificial intelligence technologies, including machine learning, natural language processing (NLP), and real-time speech recognition, to transcribe and visualize the data, facilitating a streamlined review process.
  4. Data Categorization and Filtering: The final stage involved a meticulous categorization and filtering of the data by our team. This ensured the culling of irrelevant information and the highlighting of pertinent data, paving the way for an effective review by the counsel.

Through this structured approach, we transformed a chaotic dataset into a well-organized collection of transcriptions, ready for a comprehensive review. Our efforts ensured that the counsel could focus on the most relevant pieces of information, equipped with the tools and data necessary to build a robust case in the criminal trial.
