In this paper, with the goal of using Viterbi algorithm as a quick Top-down parsing procedure, a new probabilistic model called “Rule Bi-gram” is introduced. By extending rule bi-gram model, we have implemented a new parsing algorithm (VPA) based on the Viterbi algorithm. Our experiments show that although in applications in which an exact parse of the input sentence is required, this method ma...

Surgical resection of lips is a relatively rare procedure. A defective lip may cause the patient to feel socially vulnerable as well as functionally handicapped and the defect will influence the patient's self-esteem and body image. Patients with labial defects also experience speech problems along with drying and crusting of the tissues in the area of defect. The lip and cheek provide a valve ...

One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...
