Title: Voice coding transmission equipment
Inventor: ISEDA HIDEHIRA
IPC: G10L19/00
Filed: 1987-05-20
Abstract: PURPOSE:To improve the articulation of reproduced voice while improving the quality of reproduced voice with a prescribed information quantity by sending information at a joint caused at a pitch period of a coded voice signal for each fixed frame shorter than the pitch period. CONSTITUTION:A pitch period extraction section 3 extracts the pitch period from a voice signal and a coding means 4 codes a data subject to time axis compression by a time axis compression section 2. Then a joint position detection section 80 and a multiplexer section 81 synthesize a position identification data with a fixed length representing the position of the joint (cut point) at a pitch period and a joint presence identification data with a fixed length identifying whether or not the joint of voice signals subject to time axis compression at the pitch period is included for each voice signal data at a preset fixed frame period shorter than the minimum pitch period of the voice signal subject to time axis compression to transmit the result. Since the pitch period of each pitch data is recognized accurately at the reception side, even if the frame is fixed, the transmission with less reproduction distortion is attained.
