ABSTRACT:
The present invention, according to one embodiment, comprises a speech intelligibility testing system and method. The invention comprises a sound device for producing a plurality of stimulus words to be heard by a test subject and a display means configured to display a set of word pairs corresponding to a set of contrasting speech sounds. Each word pair comprises two words which are real words with a high degree of familiarity to the test subject, and are displayed whenever a stimulus word is transmitted to the test subject. The first word of the word pair corresponds to the stimulus word, while the second word differs from the first word by at least one of the set of contrasting speech sounds. The invention also comprises a means for the test subject to select one word of the word pair after deciding which of the two words was heard. In accordance with one embodiment, the present invention employs a set of rules to generate vowel and consonant contrasts to be tested. In accordance with another embodiment, each word consists of three speech sounds, and the intelligibility test of the present invention is employed to test the contrasting speech sounds in either or all of a first consonant, a second vowel and third consonant speech sounds of the words.
