Abstract
In an LSP sound synthesizer, LSP transform parameters for three types of sounds are prestored: human, bird, and insect. For synthesis, the inverse transform is modified to increase the quality of each type of sound: a parameter converter uses a uniform-frequency distribution (of gain) for human, a mid-frequency concentration for bird, and a high-frequency concentration for insect sounds.
