Speaker recognition / sound carrier evaluation
From the voice of a blackmailer to the perpetrator. The NRW State Office of Criminal Investigation offers the possibility of investigating and evaluating the spoken word.

The "trained ear" is required in this specialist area, where audio recordings are forensically examined.
A variety of high-quality technical equipment enables voice analyses, voice comparisons, the improvement of disturbed sound recordings, the analysis of background noise, etc.

In the context of a voice comparison report, a questionable voice performance of an unknown person can be compared with comparative recordings of a possible defendant. Tampering with audio carriers, e.g. cutting out information originally recorded on the audio carrier, can be uncovered with the help of technology.
