SYSTEM AND METHOD FOR SEPARATION OF A USER'S VOICE FROM AMBIENT SOUND
First Claim
1. A system for separation of a user'"'"'s voice from ambient sound, comprising a device to be worn at a user'"'"'s ear or at least partly in a user'"'"'s ear canal and comprising a first microphone oriented acoustically outwardly towards an environment and a second microphone oriented acoustically inwardly towards said user'"'"'s ear canal, and an audio signal processing unit for processing audio signals from said first and second microphone by a blind source separation algorithm adapted to separate a user'"'"'s voice from ambient sound.

33. A system for separation of a user'"'"'s voice from ambient sound, comprising:
- a first device to be worn at a user'"'"'s right ear or at least partly in a user'"'"'s right ear canal, a second device to be worn at a user'"'"'s left ear or at least partly in a user'"'"'s left ear canal, said first device comprising a first microphone and said second device comprising a second microphone, and an audio signal processing unit for processing audio signals from said first and second microphone by a blind source separation algorithm adapted to separate a user'"'"'s voice from ambient sound.

36. A method for separation of a user'"'"'s voice from ambient sound, comprising:
-
providing the user with a device to be worn at a user'"'"'s ear or at least partly in a user'"'"'s ear canal and comprising a first microphone oriented acoustically towards an environment and a second microphone oriented acoustically towards said user'"'"'s ear canal, picking up sound by said first microphone to create a first audio signal and by said second microphone to create a second audio signal, and processing said first and second audio signals by a blind source separation algorithm in order to produce a processed audio signal wherein said user'"'"'s voice is separated from ambient sound.

37. A method for separation of a user'"'"'s voice from ambient sound, comprising:
-
providing said user with a first device to be worn at a user'"'"'s right ear or at least partly in a user'"'"'s right ear canal and a second device to be worn at a user'"'"'s left ear or at least partly in a user'"'"'s left ear canal, said first device comprising a first microphone and the second device comprising a second microphone, picking up sound by said first microphone to create a first audio signal and by said second microphone to create a second audio signal, and processing said first and second audio signals by a blind source separation algorithm in order to produce a processed audio signal wherein said user'"'"'s voice is separated from ambient sound. - View Dependent Claims (38, 39)
