Abstract (en)
[origin: EP1640972A1] The invention relates to a system for separation of a user's voice from ambient sound, comprising a device (10) to be wom at the user's ear or at least partly in the user's ear canal (12) comprising a first microphone (M1) oriented outwardly towards the environment and a second microphone (M2) oriented inwardly towards the user's ear canal, and an audio signal processing unit (24, 26) for processing audio signals from the first and second microphone by a blind source separation algorithm adapted to separate the user's voice from ambient sound.
