Abstract: A method for enhancing an audio signal by an electronic device is described. The method includes determining formant peaks based on an audio signal. The method also includes generating formant peak models. Generating formant peak models includes individually modeling each formant peak. The method further includes generating a global envelope based on the formant peak models.

Abstract: A method for noise characteristic dependent speech enhancement by an electronic device is described. The method includes determining a noise characteristic of input audio. Determining a noise characteristic of input audio includes determining whether noise is stationary noise and determining whether the noise is music noise. The method also includes determining a noise reference based on the noise characteristic. Determining the noise reference includes excluding a spatial noise reference from the noise reference when the noise is stationary noise and including the spatial noise reference in the noise reference when the noise is not music noise and is not stationary noise. The method further includes performing noise suppression based on the noise characteristic.
