| Algorithm | Description |
|---|---|
| DSP – I | A noise probability distribution model is adapted based on the similarity of current short-term statistics to the initial noise model in a logarithmic spectrum domain and used to suppress the audio noise in the spectrum domain [1]. |
| DSP – II | Similar to DSP – I, but the noise estimation is done in mel-spectrum (auditory spectrum) domain. |
| AI – I | A deep neural network model trained to separate speech from background noise. |
