Abstract
A call partner identification means identifies a call partner in order to make it possible for a user to easily identify the call partner by only the sense of hearing.

A speech processing device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- identify a call partner;
- select a background sound relevant to the identified call partner;
- and
- synthesize the selected background sound with a call speech signal,
- wherein the at least one processor is configured to execute the instructions to:
