Specific sound source automatic adjusting method and electronic device using same

An electronic device, comprising:

• a first audio recognition unit configured to perform a probabilistic identification process of the specific sound sources on an original sound signal;
• a first multi-sound source determination unit configured to determine a number of sound sources of the original sound signal according to a result of the probabilistic identification process on the original sound signal;
• a directivity analysis unit configured to perform a directionality analysis procedure on the original sound signal if the number of sound sources of the original sound signal is greater than or equal to two;
• a directional separation unit configured to separate out at least one specific directional sub-signal from the original sound signal according to the result of the directional analysis procedure;
• a second audio recognition unit configured to perform the probabilistic identification process of the specific sound sources on the specific directional sub-signal;
• a second multi-sound source determination unit configured to determine a number of sound sources of the specific directional sub-signal according to a result of the probabilistic identification process on the specific directional sub-signal;
• and
• an audio adjustment unit configured to perform a sound source adjustment procedure if the number of sound sources of the specific directional sub-signal is equal to one.
