• a driving unit for reproducing through a loud speaker the respective audio signal files of the test speech signals, the driving unit having the correct recognition results of the test speeches;
• a speech recognizer for executing a speech recognition of the reproduced audio signals in an actual environment where the speech recognizer is located to produce speech recognition results;
• and
• a performance evaluation module for evaluating the performance of the speech recognition by comparing the correct recognition results with the speech recognition results.
