Description: Excellent tool for speech intelligibility or general acoustical testing. 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 you to perform a complete end-to-end evaluation of the speech intelligibility STI from the talker’s microphone to the listener’s ears. The TalkBox features human head-like dimensions and is based on a solid-state-generator. It replays the STIPA test signal at the precisely equalized frequency response, also ensuring best performance through the internal amplifier and the precision loudspeaker. A variety of supplied or user-defined test signals may be used for different alignment applications. The NTi Audio TalkBox includes a high-precision broadband loudspeaker, with characteristic little distortion even at low frequencies. Perfect flatness of ±1 dB over the relevant frequency range and highest quality requirements are guaranteed by an individual equalization and calibration using advanced FIR filtering and DSP technology. The radiation characteristic corresponds broadly to the human mouth as defined in the ITU-T P.51 standard.Using the balanced line output, the TalkBox can also be operated as an audio signal generator. Frequency deviations while sampling - a dangerous trap when using portable CD players for STIPA measurements - are completely eliminated.Further, any external signal can be connected to the system using the balanced line input. The applied signal is seamlessly looped to the line output and simultaneously processed in the internal DSP in real-time and played through the speaker.Different Test SignalsThe TalkBox also generates additional test signals: a reference spoken sentence, white noise, pink noise, 1 kHz sine wave and the chirp for delay time measurement. Custom-designed signals may be loaded onto the CF Card and are seamlessly looped.
