Change in resonance is the most commonly experienced speech problems in children diagnosed with cleft lip and palate. The degree of nasality during normal speech production is maintained by the changes in velopharyngeal port. These variations in speech signal are reported to be successfully captured using acoustical tools like spectral analysis.
