Title: Voice communication system
Inventor: KAMAI TAKAHIRO
IPC: G10L19/00
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To add a voice rule synthesis function to a communication equipment at low cost which uses a voice CODEC. SOLUTION: A receiving section 106 receives a code group which is propagated through a communication path and transmits the group to a separating section 107. The section 107 separates the group into a voice code group and text information and outputs them to a synthesis section 115 and a language analysis section 108. The voice code group are decoded into pitch periods, line spectrum pair(LSP) coefficients and code numbers and reproduces voice by a CELP system. On the other hand, the text information is converted into pronunciation and accent information by the section 108 and the information is added with rhythm information such as a phoneme time length and pitch patterns by a rhythm generating section 110. A piece reading section 113 reads LSP coefficients and code numbers suitable for the rhythm from a piece DB 114.  The pitch frequencies are taken out from the rhythm information and inputted into the section 115 to synthesize voice.
