FORENSIC AUDIO TRANSCRIPTION
WHAT IS FORENSIC AUDIO TRANSCRIPTION?
Forensic audio transcription is the process of converting an audio file into written words. This conversion is completed under controlled conditions with an enhanced audio recording. Our forensic audio transcription services often include audio enhancement to ensure the best results.
Next, the expert witness signs off on the transcription document and its contents. In addition to signing off on the document, I label any content I am unable to understand as unclear. Finally, I commonly end the transcript with the following sentence.
“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 enhanced thousands of audio recordings throughout my career. All of these enhancements follow best practices accepted by the scientific community.
Not to mention, a forensic expert like myself goes deeper than simply listening. I also analyze and explain any hidden dialogue. This includes analyzing 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. And I do so by following the same practices that I mentioned previously. This preserves audio integrity and audio quality for both enhancement and transcription.
Once enhanced, we reattach the audio to the video recording. However, the transcript is now included on screen as subtitles. Including the transcript in this way makes the video a demonstrative exhibit for court. This exhibit is a powerful tool if the trier of fact will not allow the forensic transcript to stand alone.
CREATING A DEMONSTRATIVE EXHIBIT FOR COURT:
- First, we extract audio evidence from the original video recording.
- Second, we enhance or clarify the audio evidence.
- Third, we reattach evidence to the video recording.
- Next, we add closed captions as an overlay to the video recording.
- And finally, the video recording is exported for courtroom use.
As a result of these steps, we have created a demonstrative piece of video. This video includes 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.
Above all, forensic audio transcription services help support the evidence in your case. It is important to remember that audio isn’t always accurately reproduced to the trier of fact and opposing counsel.
AUDIO EXPERT WITNESS SERVICES
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. With this in mind, audio transcription is useful in poor listening environments where not all parties can hear a recording clearly.
