Abstract
A method for adjusting an operational characteristic of an audio device can include a series of steps. The method can include receiving a user spoken utterance from an audio speech source and detecting a position of the audio speech source relative to the audio device. The method further can include generating proximity data corresponding to the detected position and processing the received user spoken utterance with a selected signal processing technique based upon the proximity data. The signal processing technique can distinguish the user spoken utterance from background noise.
Claims23
A method for adjusting an operational characteristic of an audio device comprising:
- receiving a user spoken utterance from an audio speech source;
- detecting a position of said audio speech source relative to said audio device;
- generating proximity data corresponding to said detected position;
- and
- processing said received user spoken utterance with a selected signal processing technique based upon said proximity data, said signal processing technique distinguishing said user spoken utterance from background noise.
A method for adjusting an operational characteristic of an audio device comprising:
- detecting a position of an audio speech source relative to said audio device;
- generating proximity data corresponding to said detected position;
- and
- selectively adjusting an output level of said audio device based upon said proximity data.
An audio device, comprising:
- a proximity detector generating proximity data based on a position of an audio speech source relative to said audio device;
- at least one input transducive element, said input transducive element receiving sound and producing corresponding input audio signals;
- an output element, said output element providing output audio signals from said audio device to said audio speech source;
- audio circuitry, said audio circuitry converting said input audio signals from analog to digital format and converting said output audio signals from digital to analog format;
- and
- a processor, said processor processing said input audio signals and said output audio signals using signal processing techniques based upon said proximity data.
A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:
- receiving a user spoken utterance from an audio speech source;
- detecting a position of said audio speech source relative to said audio device;
- generating proximity data corresponding to said detected position;
- and
- processing said received user spoken utterance with a selected signal processing technique based upon said proximity data, said signal processing technique distinguishing said user spoken utterance from background noise.
