Abstract
The present invention guides a talker into a narrow sensitivity region by providing a light that is only visible when the talker's eyes are just above the sensitivity region of a microphone. When the talker keeps the light within his sight while speaking, there is no wavering problem. If the talker cannot see the light, then he is outside the sensitivity region and is alerted to a potential wavering problem by not seeing the light. In this way, the present invention takes advantage of the fact that the talker's eyes are located in close proximity to his mouth. In addition, high frequencies emanating from the mouth are highly directional and applications with speech input, such as speech recognition, function better when these high frequencies are available for analysis.
Claims25
An apparatus, comprising:
- an enclosure having an opening;
- and
- a light-emitting device inside the enclosure;
- wherein the light emitted through the opening is only visible to a speaker when the speaker's mouth is within a sensitivity region of a microphone.
An apparatus, comprising:
- an enclosure having an opening to a cavity;
- a device to emit light at the bottom of the cavity;
- and
- a cover over the light-emitting device to diffuse the light;
- wherein the light emitted from the opening is only visible to a speaker when the speaker's mouth is within a sensitivity region of a microphone.
A system, comprising:
- a microphone having a sensitivity region;
- and
- a plug capable of coupling to the microphone, the plug having an enclosure and a light-emitting device inside the enclosure to provide visual feedback to direct a speaker to stay within the sensitivity region.
A method, comprising:
- providing an enclosure having a bottom, an opening, and a depth;
- attaching a light-emitting device to the bottom of the enclosure, wherein the light-emitting device has a top surface;
- calculating an angle theta (θ) so that the light-emitting device is only visible to a talker when the talker's mouth is within a sensitivity region of a microphone;
- and
- manufacturing the opening and depth of the enclosure so that the angle theta (θ) is an angle between the top surface of the light-emitting device and a projection line drawn from an edge of the opening to an opposite edge of the light-emitting device.
