FORENSIC AUDIO TRANSCRIPTION
WHAT IS FORENSIC AUDIO TRANSCRIPTION?
Forensic audio transcription is the scientific observation of words under controlled conditions derived from an enhanced audio recording. Audio enhancement is the process of removing unwanted sound and enhancing the wanted sound. Additionally, our audio transcription services often include the enhancement of dialogue.
Then, the expert witness signs off on the forensic transcript document and its contents. I label content I am unable to understand as unintelligible.
The transcript most commonly ends: “I reserve the right to amend my conclusions and opinions as additional materials provided in conjunction with future oral testimony. Pursuant to 28 U.S.C. Section 1746, I declare under penalty of perjury that the foregoing transcript is true and correct.
A FORENSIC APPROACH TO AUDIO TRANSCRIPTION
I have forensically enhanced thousands of audio recordings using principles accepted in the scientific community. An expert like myself goes deeper than simply listening. I analyze and decipher any hidden dialogue.
With this intention, I also analyze recording details such as syllables and formatting in a spectrogram. A spectrogram is a visual display of the sound.
FORENSIC AUDIO TRANSCRIPTION SERVICES FOR VIDEO
I often enhance and transcribe audio within video recordings. I follow the same procedures to preserve audio integrity and quality for enhancement as well as transcription.
Once enhanced, we reattach the audio to the video recording. The transcript is now included on screen as subtitles, making the video a demonstrative exhibit for court. This exhibit s a powerful tool if the trier of fact will not allow the forensic transcript to stand alone.
CREATING A DEMONSTRATIVE EXHIBIT FOR COURT:
- Audio evidence extracted from original video recording
- Audio evidence enhanced or clarified
- Evidence then reattached to the video recording
- Closed captions added as an overlay to the video recording
- Video recording exported for courtroom use
As a result, we have a demonstrative piece of video with forensically enhanced audio and transcribed words on screen. Then the exhibit becomes valuable based on its diverse functionality. Not to mention, it has been created based on a scientific foundation for the trier of fact.
However, the bottom line is that forensic audio transcription services help support the evidence in your case. It is important to remember that audio isn’t always reproduced to the trier of fact, opposing counsel, and the jury accurately.
AUDIO EXPERT WITNESS
Primeau Forensics often provides audio enhancement to help the court better understand the events as they occurred. In addition to enhancement, we also offer transcription services so the judge and jury can follow along with the evidence. Subsequently, audio transcription is extremely useful in poor listening environments where not all parties can clearly hear the recording during playback.
