Abstract
A system and method for testing communication devices, such as speakerphones, are disclosed. In one embodiment, a two-way conversation is pre-recorded for playback through one or more test communications devices to evaluate communications device performance. The test set-up permits the recording of a two-way full-duplex communication onto two or more channels of the same recording/playback device, thereby preserving the content and timing relationships between speech segments. A comparison can be made between the live conversation and the conversation as it was realized in the playback condition over a test communications device. The original and the test will be different based on the performance of the communications device. This method decreases the test time and provides other efficiencies useful in connection with testing, evaluation and quality control for communications device acoustic and network performance testing.
