Voice changing device

SRS Voice Changer is a specialized device designed for the purpose of making the protected witness unrecognizable by the voice

Available models:
SRS VC12 desktop model (built-in microphone, automatic modes of voice transformation)
SRS VC13 rack model (with external microphone, automatic and manual modes of voice transformation)

These voice changing devices are designed to change the voice in order to exclude the possibility of identifying the speaker. The device can be used for both male and female voices

The devices are used to ensure the unrecognizability of the protected person (witness, victim, etc.) at questioning (interrogation) during the court proceeding or pre-trial investigation
Easy integration with recording and video conferencing systems (both hardware and software) allows for remote interrogation
Currently, thousands of voice-changing devices are successfully used in the courts of the Republic of Kazakhstan, Republic of Kyrgyzstan, Bulgaria, Spain, Hungary, Turkey, Ukraine, etc.
