Sound reproducing device and sound reproduction method for echo cancelling and noise reduction

A sound reproducing device, comprising:

• a communication unit that transmits/receives signals;
• at least one sound output unit that outputs sound based upon a signal having been received at said communication unit;
• a sound pickup unit that picks up sound containing noise and generates audio data;
• an echo canceller unit that stores an echo signal contained in the signal received at said communication unit and generates a dummy echo signal to be used to prevent said echo signal from returning to a transmission side of said communication unit by attenuating said echo signal based upon said echo signal having been stored;
• and
• a noise reducing unit that generates a cancel signal to be used to cancel noise based upon said audio data of the sound having been picked up at said sound pickup unit and outputs a composite signal generated by combining said dummy echo signal and said cancel signal.
