Abstract

A device and method are disclosed for testing the intelligibility of audio announcement systems. The device may include a microphone, a translation engine, a processor, a memory associated with the processor, and a display. The microphone of the analyzer may be coupled to the translation engine, which in-turn may be coupled to the processor, which is in-turn may be coupled to the memory and the display. The translation engine can convert audio speech input from the microphone into data output. The processor can receive the data output and can apply a scoring algorithm thereto. The algorithm can compare the received data against data that is stored in the memory of the analyzer and calculates the accuracy of the received data. The algorithm may translate the calculated accuracy into a standardized STI intelligibility score that is then presented on the display of the analyzer.

First claim

The invention claimed is:

1. An intelligibility testing device comprising:
an audio input device;
a translation engine coupled to the audio input device and configured to receive audio data from the audio input device and to convert the received audio data to output data;
a processor coupled to the translation engine and configured to receive the output data from the translation engine and to compare the received output data to stored test data to generate an accuracy score re…
