Figure 1From: Mismatch negativity in children with dyslexia speaking Indian languages(a to f). The figure shows spectrograms of six syllables used to elicit MMN. The total duration of stimuli /tΣa/, /dZa/, /sa/, /da/&/δ8a/ was approximately 250 ms. Whereas, duration of das/ was 175 ms. All the syllables spoken by an adult male speaker were digitally recorded at a sampling frequency of 16 kHz and 16-bit digitisation. They were then edited using analysis by synthesis method to achieve the target duration and were normalized.Back to article page
