The subjects developed production are placed relatively high demands on reliability, durability, practicality of use, durability but also a low cost, short production time, and other available materials. Therefore, efforts to find solutions and structures that can meet even in difficult conditions and yet retain the desired characteristics within the desired range. The presented study addressed the possibility of implementing the methods for the detection of changes of parameters influence the overall behavior of the system in MATLAB. Easy to enter tasks and advanced tracking options enable speech systems to better understand their immanent properties, determine and identify the parameter values in the range of optimum response, expect and anticipate possible impacts of changes in overall system behavior in real conditions.
