Abstract
A method of speech enhancement in a room () includes the steps of capturing audio signals from a speaker's voice by a microphone (), estimating an ambient noise level in the room from the captured audio signals, processing the captured audio signals by an audio signal processing unit (), estimating a reverberation level, determining the gain to be applied to the captured audio signals by the audio signal processing unit according to a comparison between the estimated ambient noise level and the estimated reverberation level, and generating sound according to the processed audio signals by a loudspeaker arrangement () located in the room, wherein the reverberation level is the level of reverberant components of the sound generated by the loudspeaker arrangement.
