PROBLEM TO BE SOLVED: To record a coded voice signal being a voiced signal for a long time to a recording section by recording accessory information to the recording section when the coded voice signal to be recorded in the recording section is a silent. SOLUTION: A control section 14 that detects voice/silence information discriminated by a voice processing circuit section 3 discriminates a silence period of a coded voice signal to be recorded in a recording section 11. Then the coded voice signal discriminated to be in a silence period is not sent to a recording information generating section 16 as it is but the silence information is sent from the control section 14 to an accessory information generating section 15 and the accessory information generating section 15 generates accessory information denoting the silence state. Furthermore, a recording information generator separate section 16 generates recording information based on the accessory information and the voiced coded voice signal. That is, the coded voice signal for a period when discriminated to be silent is replaced with a signal with a comparatively short signal denoting the silent state and the resulting signal is recorded in the recording section 11. |
