Audio Transcription Services
Audio transcription is the process of converting speech from audio and video recordings into written text for use in legal or investigative contexts. The transcription process involves applying advanced technology to identify speech, the number of speakers, and each speaker.

Benefits of Our Transcription Services
Our transcriptions are generated and validated first by a qualified forensic technician, then by a forensic expert. We pride ourselves on the accuracy of the final product, a Certified Audio Transcript, which is considered an accurate depiction of the audible events, most discernible by the average listener. The final certified transcript and enhanced audio recording simplify the process for an investigative body or the trier of fact (Judge and Jury) to follow the video and audio evidence as it is played back in courtrooms worldwide.
Audio Transcription Process
1. Evidence Intake
We can provide audio transcription services from common audio formats like WAV, MP3 and M4A. We can also provide audio transcription services from common video recorders, including Ring cameras, key fob cameras, button cameras, dash cameras, and body-worn cameras.
2. Audio Signal Preparation
Primeau Forensics converts and cleans captured sound waves to ensure maximum fidelity and minimal noise interference so that your case highlights the truth.
3. Audio Enhancement
Some recordings contain distortions or other noises that make it difficult to detect or identify speech. Audio enhancement can help increase the intelligibility of poor-quality or unclear recordings throughout the transcription process. This process is thoroughly documented to meet best practices in Digital Forensics.
4. Critical Listening
Evaluate the recorded evidence to gain context. This is a critical juncture for setting expectations regarding what is possible for transcription. Transcription for context and utterances is the key takeaway. We do not always determine an utterance or word spoken.
5. ASR Transcription (Automatic Speaker Recognition)
ASR (automatic speech recognition) tools that utilize open-source artificial intelligence models like Open Whisper are considered as accurate, if not more accurate than, the human ear when applied next. This methodology is most effective for recordings with multiple speakers or lengthier audio/video recordings. This process not only identifies speech but can also identify speakers through a process called Speaker Diarization.
6. Validate Transcription
A transcription includes timestamps, which help the listener identify the specific portion of speech being transcribed, the speaker responsible for the speech, or other sounds.
7. Generate Exhibits & Certification
The forensic transcript may be used as evidence in court, during police investigations, or for intelligence gathering, authentication, and discovery purposes.
Expert Witness Services
Primeau Forensics can also provide an audio forensic expert who offers unbiased testimony based on our experience and findings. Our experts are trained to serve as witnesses and undergo thorough preparation to strengthen their testimony.
They also provide detailed reports about how audio enhancements and transcriptions were conducted, as well as their opinions on the results.
