Zusammenfassung:Provided in the present disclosure are a method and an apparatus for suppressing noise by calculating a speech presence probability, a storage medium, and a terminal. The method includes: obtaining an input signal, and converting the input signal from a time-domain signal to a frequency-domain signal (S101); calculating a real-time power spectrum of the frequency-domain signal, and tracking a minimum power in the real-time power spectrum (S102); performing noise estimation based on the minimum power to obtain an estimated noise power spectrum (S103); calculating a gain coefficient based on the estimated noise power spectrum, and enhancing the frequency-domain signal based on the gain coefficient to obtain an enhanced frequency-domain signal (S104); and converting the enhanced frequency-domain signal to a time-domain signal to obtain an output signal (S105).
