This paper presents an excitation source model for speech compression and synthesis, which allows for a degree of voicing by mixing voiced (pulse) and unvoiced (noise) excitations in a frequency—selective manner. The mix is achieved by dividing the speech spectrum into two regions, with the pulse source exciting the low—frequency region and the noise source exciting the high—frequency region. A parameter Fc determines the degree of voicing by specifying the cut—off frequency between the voiced… CONTINUE READING
