PCT No. PCT/JP91/00408 Sec. 371 Date Nov. 12, 1991 Sec. 102(e) Date Nov. 12, 1991 PCT Filed Mar. 28, 1991 PCT Pub. No. WO91/15901 PCT Pub. Date Oct. 17, 1991.An error detection method used for digital communication which intends to reduce the probability of outputting the speech obtained by decoding the data that includes an error. The speech data encoded in an error detection code and an error correction code is transmitted. On a receiving side, the data with an error detected in either one of decoding of the error correction code and CRC checking is interpolated so that it is possible to prevent the data which actually includes an error from being decoded into speech as it is.
