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.

Claims

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;

wherein

the 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.

2. The wireless headset of claim 1, further comprising a timer circuit, the timer circuit measuring the second length of time.

3. The wireless headset of claim 1, further comprising an adjustable decibel setting device for setting variable ambient noise levels.

4. The wireless headset of claim 1, further comprising an adjustable decibel setting device for setting activating noise levels.

5. The wireless headset of claim 1, further comprising a fuzzy logic circuit which samples the background noise level to determine the ambient noise level.

6. The wireless headset of claim 1, wherein the activating noise level must occur for 300 milliseconds in order allow the off hook initiation.
