Many young children have speech disorders. The research focused on one such disorder, known as specific language impairment (SLI) or developmental dysphasia in Czech (DD). A major problem in treating this disorder is the fact that specific language impairment is detected in children at a relatively late age. For successful speech therapy, early diagnosis is critical. This paper provides the issue of identifying SLI in children on the basis of their speech and presents two different approaches to this issue using. The First access is a new method for detecting specific language impairment based on the number of pronunciation errors in utterances. The success rate of detection of children with SLI is higher than 93%. An advantage of this method is its simplicity in the form of a simple test. This test is used in a mobile application SLIt Tool which is designed for iPad. The second method is based on the acoustic features of the speech signal. The feature set used to analyze speech data contains 1582 acoustic features and the success rate is almost 97%. An advantages of these different methods is that they could be used together to develop of the robustness automatic detection system.
