Mismatch negativity response parameters; latency, amplitude, and duration - to natural Arabic and natural English CV syllables - were obtained from normal-hearing adult Egyptians, in two experiments. In the first experiment, MMN was obtained in response to English CV syllable paradigms (Ba-Wa) and (Ga-Da) differing in formant duration and start of third formant, respectively. In the second experiment, MMN response for Arabic paradigm (Baa-Waa), English paradigm (Ba-Wa), and for Arabic-English paradigm (Waa-Wa) was obtained. Results revealed that the three levels of speech representation; acoustic, phonetic and phonologic could be probed preattentatively by MMN. The acoustic properties of speech signal are processed earlier than the phonetic and phonologic properties.
