PROBLEM TO BE SOLVED: To make a functional word, etc., included in speach easy to listen. SOLUTION: An analog speech signal is converted into a series of speech data by an A/D converter 21, and a series of speech data are divided into the word data by a word blocking means 23, and the word data whose signal level is lower than a prescribed threshold value R among the divided word data are extracted by a word data extraction means 24. The signal level of the extracted word data is amplified by an amplifier means 25, and the amplified word data and the other data are synthesized in order of input speech by a synthetic means 26, converted into the analog speech signal, and outputted. |
