Sixth European Conference on Speech Communication and Technology
We are presenting a tutorial which describes how a human produces speech and how this speech production can be simulated by an LPC vocoder.In the first section, we describe that speech is generated by a periodic or noise-like signal of the vocal cords which excites the articulation tract (mouth, nose cavity). The next section explains how this natural sound production is simulated by an LPC vocoder system. The vocoder was chosen because it gives the user access and manipulation possibilities to the speech parameter, above all, the pitch and the formant structure, expressed by the LPC coefficients. The main advantage of the tutorial are its numerous interactive functions. The tutorial is based on HTML pages and Java applets and can be downloaded from the WWW.
