The invention relates to a pick-up method and
system based on a
microphone array; the method comprises the steps of 1, using the
microphone array to pick up and output one of multiple speech signals for speech
activation detection, and judging whether a speech activation
signal occurs or not; if yes, executing step 2; if not, repeating the step 1; 2, performing sound source positioning on the multiple speech signals to obtain a sound source positioning direction; 3, subjecting the speech
signal of the sound source positioning direction to speech augmentation to obtain an augmented speech
signal; 4, subjecting the augmented speech signal to speech wakeup detection, and judging whether speech wakeup is detected or not; if yes, executing step 5; if not, repeating the step 1; 5, allowing the
microphone array to pick up and output the multiple speech signals; 6,
processing the multiple speech signals as one signal that is output finally as picked speech. Speech signals can be better picked up in far field environment, particularly accurately in high-
noise environment, and an excellent solution is provided for remote
speech control.
