Frequency domain noise detection of audio with tone parameter
Abstract:
A noise detection method and apparatus are disclosed. The noise detection method includes: obtaining a frequency-domain energy distribution parameter of a current frame of an audio signal, and obtaining a frequency-domain energy distribution parameter; obtaining a tone parameter of the current frame, and obtaining a tone parameter; determining, according to the tone parameter of the current frame and the tone parameter of each of the frames in the preset neighboring domain range of the current frame, whether the current frame is in a speech section or a non-speech section; and determining that the current frame is speech-grade noise if the current frame is in a speech section and a quantity of frequency-domain energy distribution parameters falling within a preset speech-grade noise frequency-domain energy distribution parameter interval in all the frequency-domain energy distribution parameters is greater than or equal to a first threshold.
