A method of speech enhancement in a room (10), having the steps of: determining acoustic parameters of the room and a loudspeaker arrangement (24) located in the room, capturing audio signals from a speaker's voice with a microphone (12), and processing the captured audio signals with an audio signal processing unit (20). The audio signals are filtered by applying a selected frequency response curve to the audio signals, generating sound according to the processed audio signals by the loudspeaker arrangement, determining a value indicative of the overall gain applied to the captured audio signals, and selecting a frequency response curve to be applied to the captured audio signals according to the overall gain value and the acoustic parameters. |
