Interpretation terminals and method for interpretation through communication between interpretation terminals

A method performed by a mobile interpretation terminal of an initiating party for communicating with a mobile interpretation terminal of an other party, the method comprising:

• establishing a communication channel with the interpretation terminal of the other party in response to an interpretation request;
• specifying an interpretation language of the other party by receiving information about the interpretation language from the interpretation terminal of the other party via the communication channel;
• recognizing an uttered sentence from a speech signal of the initiating party;
• translating the sentence recognized by the interpretation terminal of the initiating party into the interpretation language of the other party;
• and
• transmitting the translated sentence to the interpretation terminal of the other party,
• wherein the recognizing the uttered sentence comprises:
• performing synchronization with the interpretation terminal of the other party;
• detecting noise from the speech signal of the initiating party;
• and
• performing speech recognition on the speech signal from which the noise is removed, and
• wherein the detecting the noise from the speech signal of the initiating party comprises:
• comparing the speech signal mixed with the noise from the initiating party with a noise signal transmitted from the interpretation terminal of the other party;
• and
• detecting a matching portion between the speech signal and the noise signal as the noise.
