Abstract: In accordance with various embodiments of the disclosed subject matter, a speech detection method and a related apparatus are provided. The speech detection method includes the steps of switching a speech acquisition system from a non-trigger mode into a trigger mode according to a the first preset condition, recording a trigger mode operating reference time starting from zero, and setting a non-trigger mode operating reference time to zero; acquiring speech signals by using the speech acquisition system in the trigger mode to obtain first pulse-code modulation data; extracting the first pulse-code modulation data during the trigger mode operating reference time according to a second preset condition; and matching the first pulse-code modulation data during the trigger mode operating reference time with a speech model to obtain speech data.
