Audio/Video Forensic & Restoration Associates –

2 Step Voice comparison process:

Step 1:

The Computer Based Spectrum Analysis:

• Using our Digital Audio Workstation (D.A.W.) we will enhance and transcribe the “unknown” voice recording.
• An “exemplar” sample will be recorded at our facility (Using our sister company Audiomatrix Studios)
  • This can be done either by phone or in person
• We match the words from both the “unknown” and “exemplar” samples.
• These matched words are then compared using the Computer Based Spectrum Analysis.
  • The result is a graphic print displaying two lines for each pair of word samples.
• The sets of graphs are examined and compared.

Step 2:

Qualified Aural Listening:

• With repeated listening to the comparison samples, a subjective but informed impression is reached based on the following factors of Speech and voice qualities:
  • Timbre/Tone
  • Accents
  • Gender
  • Age
  • Emphasis of words and phrases
  • Inflection
  • Cadence (How words and phrases are grouped together by the individual)
• Our Associates have many years of experience listening to audio recordings, transcribing voices and performing voice analysis. This allows us to determine with a reasonable degree of certainty if the voices are:
  • Likely matches
  • Not likely matches
  • Inconclusive
