Electronic device and control method thereof

An electronic device comprising:

• a speech receiver;
• and
• a processor configured to:
• based on a user's speech being received via the speech receiver, identify an accumulation level of utterance history information corresponding to characteristics of the user's speech;
• based on the accumulation level of the utterance history information being lower than a predetermined threshold level, provide response information corresponding to the user's speech based on user information related to the characteristics of the user's speech;
• and
• based on the accumulation level of the utterance history information being equal to or higher than the predetermined threshold level, provide response information corresponding to the user's speech based on the user information and the utterance history information,
• wherein the utterance history information comprises information on a number of times of errors provided along with failure of recognition of the user's speech, and
• wherein the processor is configured to:
• based on the user's speech being received, identify the number of times of errors based on the utterance history information corresponding to the characteristics of the user's speech;
• and
• based on the number of times of errors being equal to or more than a predetermined number of times, provide guide information for speech recognition success.

A method for controlling an electronic device, the method comprising:

• based on a user's speech being received, identifying an accumulation level of utterance history information corresponding to characteristics of the user's speech;
• and
• based on the accumulation level of the utterance history information being lower than a predetermined threshold level, providing response information corresponding to the user's speech based on user information related to the characteristics of the user's speech, and based on the accumulation level of the utterance history information being equal to or higher than the predetermined threshold level, providing response information corresponding to the user's speech based on the user information and the utterance history information,
• wherein the user information comprises information on an age group of a user who utters the user's speech,
• wherein the method further comprising, based on the age group being equal to or higher than a predetermined threshold age, operating in a speech recognition mode during a predetermined time from when a user's speech for triggering the speech recognition mode of the electronic device is received, and based on the age group being lower than the predetermined threshold age, extending the predetermined time.
