The TalkBox is an acoustic signal generator for speech intelligibility measurements in evacuation and announcement systems, as well as for level alignment of teleconference or other audio systems. It allows performing the complete end-to-end evaluation of the speech intelligibility STI-PA from the talker’s microphone to the listener’s ears.
The TalkBox simulates a human talker (60 dBA @ 1 meter according to IEC 60268-16) with the STI-PA test signal and spoken messages. Further it provides a wide range of test signals like sine, pink noise, white noise and delay.
