Electronic device and voice control method thereof

An electronic device comprising:

• a voice input unit;
• a play unit;
• a storage unit storing a plurality of modules, a conversation database of responses each corresponding to a content of voice signals, and an association table between different ranges of voice characteristics and styles of response voice, each range of voice characteristics being associated with a particular style of response voice;
• and
• a processor to execute the plurality of modules,
• wherein the plurality of modules comprises:
• an obtaining module to obtain voice signals input via the voice input unit;
• a response determining module to determine which content is input according to the obtained voice signals, and search in the conversation database to find a response corresponding to the input content;
• a voice analyzing module to analyze voice characteristics of the obtained voice signals to differentiate between various users of the electronic device, compare the voice characteristics of the obtained voice signals with the pre-stored ranges, and select the associated response voice, wherein the voice characteristics comprise voice pitch, voice intensity, and speed of speech of the voice of the obtained voice signals;
• and
• an output control module to output the found response using the associated response voice via the play unit, wherein the associated response voice has different voice pitch, same voice intensity, and same speed of speech with respect to the input voice signals.
