Voice Biometric Analysis, Comparison, and Identification

Through voice spectral analysis, comparison, and identification, we can determine whether a voice had been spliced, modified, tampered with, or post-produced. We can also determine to what extent an unknown voice sample matches a known object's voice exemplar. By analyzing the acoustic characteristics of mechanical, ship engine, mobile equipment, and other sound effects, we can assist in identifying the type and even exact model of the unknown mechanical sounds based on the comparison against known voice samples.

●About the Muscene Voice Forensics Laboratory

Muscene Voice Forensics Laboratory has accumulated extensive field experience and theoretical foundations in acoustic physics, acoustic psychology, spatial acoustics, human voice biometrics, audio forensics, speaker recognition, signal-noise control, noise reduction, frequency and sound information extraction, audio synthesis, audio signal enhancement, environmental voiceprint analysis, file conversion and audio compression, audio encoding and decoding, and other related fields.

The parent company of MuScene Voice Forensics Laboratory, the MuScene Recording Studio, had been requested to provide speech analysis, speaker identification, speaker authentication, and other related audio forensics services to the general public back in 2013, when a drastic domestic imbalance between customer demands and service providers in the broad scope of recorded audio evidence existed. Since then the laboratory has been routinely appointed by District Courts for providing outsourced services in various scenarios, ranging from Karaoke copyright infringement disputes, apartment mansion noise disturbance issues, contract frauds in banking institutions, to typical litigations involving falsified recorded conversations.

In July 2015, the MuScene Voice Forensics Laboratory was officially founded, and all forensics related business previously provided by the Studio, including consulting, speaker identification, analysis, speech signal enhancement, basic research, and development, have been transferred to the laboratory for continued expansion of our capacity in research and service quality. Outsourcing services demanded by regional courts and impartial third-party forensic notarization institutions are also among our service scope. The MuScene Voice Forensics Laboratory has played important role as a neutral third-party forensic services provider in upholding the regional justice system.

To have your recorded audio data processed by the MuScene Voice Forensics Laboratory, you need to prepare and submit the following:

1. An authentic copy of the digital source audio file,
2. A written description/summary of the nature of serve you’re looking for,
3. In the case of speaker identification, a recorded speech of the subject person with quality no worse than that of your subject audio recording, otherwise, a legal and mandatory speech exemplar must be scheduled.
4. Transcript of the recorded speech with accurate speaker annotation.

Important message for potential customers: as data originality is of vital importance to recorded audio evidence, KEEP YOUR ORIGINAL COPY OF RECORDED EVIDENCE INTACT before you are instructed by one of our engineers as to how to submit your data for evaluation; simple operations such as file copy may sometimes inadvertently result in data modification with ensuing loss of its probative power. All data manipulation should only be handled by personnel trained for such operation!

In the event that your original acoustic data requires signal enhancement and noise reduction before further aural examination is possible, DO LEAVE THESE TASKS FOR MuScene’s FORENSIC EXAMINERS LEST YOUR ORIGINAL DATA SHOULD BE INADVERTANTLY MODIFIED WITH ENSUING LOSS OF ITS VIABILITY AS LEGAL EVIDENCE.
