INTRODUCTION

The TalkBox is an active acoustic signal generator for speech

intelligibility measurements in evacuation and announcement

systems, as well as for level alignment of teleconference or any

audio system incorporating a microphone input. It allows perfor-

ming complete end-to-end evaluation of the speech intelligibility

STIPA from the talker’s microphone to the listener’s ears.

The TalkBox simulates a human talker (60 dBA @ 1 meter ac-

CF Card containing

Test Signals & Calibration Data

cording to IEC 60268-16) with the STIPA test signal and spoken

messages. Further it provides a wide range of test signals like

sine, pink noise, white noise and delay.

The TalkBox features human head-like dimensions and is based

on a solid-state-generator. It replays the STIPA test signal with

a precise frequency response, individually equalized for each

TalkBox, also ensuring best performance through the internal

amplifier and the precision loudspeaker. A variety of supplied or

user-defined test signals may be precisely output for different

alignment applications.
