Abstract
The present invention is directed to a wireless telephone having a first microphone and a second microphone and a method for processing audio signal in a wireless telephone having a first microphone and a second microphone. The wireless telephone includes a first microphone, a second microphone, and a signal processor. The first microphone outputs a first audio signal, the first audio signal comprising a voice component and a background noise component. The second microphone outputs a second audio signal. The signal processor increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
Claims28
A wireless telephone, comprising:
- a first microphone that outputs a first audio signal, the first audio signal comprising a voice component and a background noise component;
- a second microphone that outputs a second audio signal;
- and
- a signal processor that increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
A method for processing audio signals in a wireless telephone having a first microphone and a second microphone, comprising:
- outputting a first audio signal from the first microphone, the first audio signal comprising a voice component and a background noise component;
- outputting a second audio signal from the second microphone;
- and
- increasing a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
A corded telephone, comprising:
- a first microphone that outputs a first audio signal, the first audio signal comprising a voice component and a background noise component;
- a second microphone that outputs a second audio signal;
- and
- a signal processor that increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
A headset telephone, comprising:
- a headset having a first microphone that outputs a first audio signal, the first audio signal comprising a voice component and a background noise component;
- and
- a handset having a second microphone that outputs a second audio signal and a signal processor that receives the first and the second audio signals and increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
A headset telephone, comprising:
- a headset having a first microphone that outputs a first audio signal, the first audio signal comprising a voice component and a background noise component, and the headset having a second microphone that outputs a second audio signal;
- and
- a handset having a signal processor that receives the first and the second audio signals and increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
A headset telephone, comprising:
- a headset having a first microphone that outputs a first audio signal, the first audio signal comprising a voice component and a background noise component, and the headset having a second microphone that outputs a second audio signal;
- and
- the headset having a signal processor that receives the first and the second audio signals and increases a ratio of the voice component to the noise component of the first audio signal based on the content of at least one of the first audio signal and the second audio signal to produce a third audio signal.
