DIVA model based on the constant delay mechanism

A lot of speech models emerge as human speech perception are more and more attention in recent years, especially which are built according to clinical trial data. DIVA (Direction Into Velocities of Articulators) is a clinical data model based mathematical model that can accurately describe the role of the human brain involved in speech production and speech understanding by the region, and simulate the process. Studied, we found the model in the simulation pronunciation and realistic physiological processes have some access, and did not achieve the desired results because that the voice processing is too complex. Thus, this paper uses the constant delay mechanism, makes its workflow more reasonable and having a realistic sense of simulation results. In the simulation experiment, after introducing the new delay module, the sound process is satisfactory, it can be more close to the physiological processes.
