Speaker Recognition.

The issue of identifying and comparing a speaker’s voice in a recording has become an important component in recent years. 

In Conclusive Evidence’s sound lab, two key tools for reviewing and verifying a speaker’s voice are:

1. Biometric Speaker Detection Engine

2. Software for Testing and Comparing the Speaker’s Voice

With these two tools, we can answer the question of the speaker’s identity – whether it is them or not. If necessary, we can also provide an expert opinion to court.

Recognizing the speaker in a voice recording is important because in a voice recording, unlike in a video recording, we do not have the visual element that can help us confirm the identity of the speaker. Moreover, even in video recordings the visual element sometimes fails – because the image is blurry, the lens is partially blocked, the video quality is insufficient – and therefore the identity of the speaker must be verified only by identifying and verifying the audio.

In addition, new computer technologies for voice modulation are being developed daily, and speaker voice recognition is an important and reliable means to prevent attempts to tamper with evidence through these technological means.

Our expert on speaker voice authentication (certified by the Israeli courts as an expert witness for these issues) performs a check of the audio or video file using a specialized software that is approved for the identification of a speaker by the courts around the world. Our expert has many years of experience in voice tests and testifying in court on audio evidence. His expertise and experience in the operation of dedicated software – which examines the identity of a speaker’s voice in comparison with an authenticated sample of any speaker(s) according to several different measurable parameters – gives a certificate that verifies the speaker’s identity (or disqualifies it in case the speaker is not the same).

Any attempt at spoofing a recording by using a copycat or a similar voice would not be able to deceive the capabilities of the system.

We can perform voice recognition and authentication on audio and video recordings made in any language. The language used in the recording is unimportant (even in the case of a multilingual conversation).
