Introduction
The TalkBox is an active acoustic signal generator for speech intelligibility measurements of
evacuation and announcement systems, as well as for level alignment of teleconference or
any audio system incorporating a microphone input. In combination with the XL2, it facilitates
complete end-to-end evaluation of the speech intelligibility STIPA from the talker’s microphone
to the listeners’ ears.
The TalkBox simulates a human talker (60 dBA @ 1 meter according to the IEC 60268-16 stan-
dard) 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 preci-
sion loudspeaker. A variety of supplied or user-defined test signals may
be faithfully reproduced for different alignment application areas.
