The Fluent Audio Wireless Interview/Coaching System allows for prompting the Interviewer without interrupting the interview. Now the line of questioning can be directed without alerting the suspect that something they said was of interest. The short range (200′) of the system keeps the transmissions in house. Used with the Fluent Wireless Earpiece, this wireless interviewing system allows someone outside the interviewing room, observing the interview, to send questions to the interviewer during the interrogation, very covertly.
Basically, the interviewer wears a covert wireless receiver on their belt or in a pocket. The receiver is attached to a covert loop that hangs around the neck under the shirt. The audio from the receiver flows through the loop around the neck and inductively couples the audio into the ear piece. Additionally, the unit has 25 channels so that more than one interview can be carried out at one time.
