PHN 9618 13.8.1980 ABSTRACT Speech synthesizing arrangement having at least two distortion circuits. Speech synthesizing arrangement for use in both voice-excited channel and formant vocoders. To derive an excitation signal from a base-band, signal distortion networks are used in these vocoders. Simple distortion networks have the drawback that the natural sound of the reproduced speech signals leaves much to be desired for. Networks which give a better guarantee for a more natural speech reproductive have the drawback that they are of a rather complicated design. According to the invention, an improved natural sound of the reproduced speech is obtained, using simple networks, by generating separate excitation signals for different frequency ranges by means of at least two separate distortion networks.
