A distributed intelligibility testing system provides standardized audio tests to a plurality of remotely located client systems. The testing system includes a test manager that records a plurality of audio test words based on established intelligibility standards and generates a test protocol corresponding to the audio test words. A database receives and stores the audio test words and the test protocol. The audio test words are stored as a plurality of audio test files. Respective client systems in communication with the database receive and play the audio test files in accordance with the test protocol. The client systems record test responses when the audio test files are played. The test responses are stored in a database, and then evaluated.
