The multimodal perception and production of speech production have gained a lot of attention as a result of various studies in the 1990s up to now. Although there are discussions about the importance of the role of different perceptual systems in speech production, there is agreement over the facilitating role of vision in speech. This experimental study examines the impact of congenital visual deprivation on the production of Persian voiced stop consonants as well as the patients’ compensation strategies for producing these phonemes. The researcher recorded 864 naturally produced speech samples from eight congenitally blind children and eight sighted ones all ranging from 8 to 15 years (mean age: 13±1.69 years old) during the production of the three repetitions of the Persian stop-vowel consonants in a CV sequences. The results of The F2 and F3 formant transition analyses revealed that blindness may have an effect on the difference of offset and onset of the second formant transition. However, the onset and offset of the second and third formant transition and the difference of the offset and onset of the third formant transition were unaffected.
