Token SelectionPress F9 to open the "Select Sound" window and Select the desired Sounds, then click "OK". Here shows the example how token selection function works in consonant recognition test. •Step 1: First load the consonant recognition test by clicking Standard > Consonant Recognition Test;•Step 2: Press F9 to open “Select Sound” Window;•Step 3: Select the desired tokens, for example, if only stop consonants are needed, remove all other tokens except 6 stop consonants ;•Step 4: The original setting has 10 talkers, in the selection menu, choose subcategory selection, 10 talkers are listed in the windows, select the desired number of talkers;•Step 5: Click OK, then the new test is ready for use. There are 200 testing tokens in the original setting (10 talkers * 20 consonants). However, there are only 24 testing tokens in the new setting (4 talkers * 6 consonants). •The Screenshot of Old and New Setting is shown as follows; Generate Noisy SpeechPress F8 to open the "Calibration, Presentation, and Background" window and Select the "Test with Background Noise" and Specify the Noise Type and desired signal-to-noise ratio, then click "OK". Then click “Run” button or Press F2 to start the testing. Noisy speech signals will be generated in real time according to the noise type and desired signal to noise ratio.Cochlear Implant SimulationPress F6 to open the "Speech Processor Design" window and Enable the "Noiseband Vocoder Processor" and Specify the Parameters, then click "OK". Then click “Run” button or Press F2 to start the testing. Vocoded speech signals will be generated in real time according to the parameters specified in the vocoder setting (e.g. the number of spectral channels). The background noise setting and vocoder setting can be combined so the program can test vocoded speech sigansl under various listening conditions, such as different background noise and signal-to-noise ratio.

This function allows the user to see whether the response is correct or not. After the whole test is completed, the screen also shows the detailed analysis of the results, including the percent correct, confusion matrix, information transmitted, percent correct for individual talker etc. Also, all these detailed test results and analysis can be printed out by press “Ctrl+P” or Press the “Print” button in the toolbar (2nd button in the toolbar).
