VOICE SYNTHESIS DEVICE

摘要

A voice synthesis device capable of producing a composite tone rich in emotion by producing a composite tone having its tone quality changed according to an emotion status, wherein a parameter producing unit (43) produces a conversion parameter and a synthetic control parameter based on status information indicating the emotion status of a pet robot. A data converting unit (44) converts the frequency characteristics of phoneme piece data as voice information. A waveform producing unit (42) obtains necessary phoneme piece data based on phoneme information contained in the text analysis results, and connects the phoneme piece data together while processing the data based on rhythm data and the synthetic control parameter to produce composite tone data having corresponding rhythm and tone quality. The device is applicable to a robot that produces composite tones.
