Sound localization method, apparatus and device

A sound localization method, characterized by comprising:

• collecting a multi-channel voice signal through a directional microphone array;
• determining a steering vector comprising phase information and amplitude information according to array shape information and microphone pointing direction information;
• and
• determining sound direction information according to the steering vector and the multi-channel voice signal.

A sound localization apparatus, characterized by comprising:

• at least one processor and a memory;
• the memory stores a computer executable instruction;
• and
• the at least one processor executes the computer executable instruction stored in the memory to enable the at least one processor to:
• collect a multi-channel voice signal through a directional microphone array;
• determine a steering vector comprising phase information and amplitude information according to array shape information and microphone pointing direction information;
• and
• determine sound direction information according to the steering vector and the multi-channel voice signal.
