Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a speech processing device which reduces calculation amount of decoding processing required when a plurality of coded speech data are interactively reproduced by the operation of a user, and increases the efficiency of the decoding processing, and to provide a speech processing method, a program and a recording medium.SOLUTION: A speech processing device includes: decoding a plurality of coded speech data; subjecting the decoded data to inverse quantization to generate frequency data; subjecting the respective frequency data to processing treatment; combining the processed frequency data with each other; and then subjecting the single combined frequency data to conversion processing to generate speech data.
