Audio Evidence

Epiq audio evidence experts, applied intelligence, and processes helps corporations and law firms make the case without breaking the budget


Audio evidence is often a critical source of discovery content in litigation and regulatory investigations, as well as in regular monitoring activity and internal investigations. Managing audio evidence can be costly and time consuming, which is why clients using Epiq’s audio solutions reduce the cost and risk associated with voice recordings.

Identification and collection 

We help you produce comprehensive data maps and identification plans, as well as manage the process of minimising data extraction from tape or archive. You’ll have all the tools you need to quickly and efficiently find the voice evidence you need, when you need it.

Automatic speech recognition 

Epiq’s partners with best of breed technologies to generate accurate transcripts of conversations, with associated analytics such as speaker recognition and mood analysis.


You have a choice of review services, from first-pass relevancy review of voice recordings to in-depth issue coding and privilege review.

Compliance and monitoring 

We work with you to design and implement compliance monitoring programs that document all required data-driven elements and reduce organisational risk. Our process/workflow ensures that implementation is rigorous, well-documented and defensible in case of future scrutiny. Your compliance teams also will be able to incorporate audio seamlessly into existing programs for monitoring textual electronically stored information (ESI).

Analysis, culling and prioritising 

When audio data and its associated metadata are initially collected and verified, there is often a much higher volume than is practical or necessary to review. We help reduce the cost and time of manual audio evidence review through identification of silence, inspection of metadata, indexing of voice recordings, automatic speech recognition technology and sophisticated analytical tools.
