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.
