Voice activated wireless phone headset
First Claim
1. A wireless headset for connection to a telephone comprising:
- a noise level recognition circuit operatively able to activate the headset;
the noise level recognition circuit distinguishing voice levels below a first level decibel level as an ambient noise level;
the noise level recognition circuit distinguishing voice levels above a second decibel level as the activating noise level;
whereinthe noise level recognition circuit initiating off-hook operation of such telephone if the activating noise level is detected during a 5 second period of time, following a first length of time used for detecting the ambient noise level.

Abstract
A voice activated wireless phone headset whereby power control, timer and noise level recognition circuits sample ambient noise/voice levels and at predetermined levels provide an “off-hook” telephone condition. The light weight headset fastens around the ear with an adjustable microphone tube that extends towards the user'"'"'s mouth thus emphasizing vocal noises. The headset will, on receiving a ring signal, begin measuring a pre-selected length of time. If the voice level of the user increases above a threshold level, the headset unit will then send an activation signal to the base unit causing an “off-hook” condition and allowing a phone conversation. A wireless connection to a base unit exists. Bandpass filters, levels, digital signal processing and other methods allow more efficient voice and/or word recognition.
