All participants were randomly selected from the outpatient clinic of phoniatrics from five speech disorders affecting speech intelligibility.

Results The results showed highly significant correlation between the scores of the Arabic speech intelligibility test and the average scores of the raters. Conclusion The developed test proved to be valid and reliable for measuring speech intelligibility and could be categorically classified into ranges of severity.
