专利汇可以提供Sound synthesizer专利检索,专利查询,专利分析的服务。并且PURPOSE: To generate a synthetic sound with neither discontinuous waves of a connection part nor variation in pitch frequency by selecting the shift amount of data when the sum of absolute values of level differences of connection-part sampling values between preceding and following phoneme waveforms becomes minimum.
CONSTITUTION: In memory units 103 and 104, an analog input signal sampled according to clocks is stored, and binary signal converter 124 converts sampling values of the connection part of a preceding phoneme waveform and following phoneme waveform into binary signals of polarities equivalent to the input signal. Here, arithmetic processor 121 sums up absolute values of level differences and the shift amount of sampling data when the calculation value becomes minimum is selected among calculation values through its calculation operation, so that memory units will be clock-controlled by programs to adjust the time axis of the following connection phoneme element. Consequently, a synthetic sound can be obtained with neither discontinuous waveforms of the connection point nor variation in pitch frequency.
