Estimation of possibilities connected with usage of electroglotography method in speech signal analysis

The research presented in this paper deals with the speech signal with use of elecroglotography method analysis issue. This is an instrumental analysis, so the device called Laryngograph is presented, as a practical application. In this paper capabilities of this device are estimated. The very interesting fact is that the visualization of the speech signal obtained using Laryngograph allows to detect its acoustically and phonetically most important features, and presenting them in a graphical form. The analysis process performed using a computer and the specified computer attachment is easier, faster and ensures higher quality than other methods. Computer voice recording enables not only visualization but also objective assessment and its repetitiveness. In the context of presented questions, practical capabilities of integrated system for speech examination - Speech Studio are discussed.
