1. A non-transitory computer readable storage medium storing a program of instructions executable by a machine to perform a method of preventing unintended distribution of audio information, the method comprising:
- analyzing by a processor, audio data of a speaker'"'"'s speech received by a microphone before the audio data is distributed via the microphone;
determining automatically by the processor, from the analyzing whether the speaker'"'"'s speech is intended to be distributed to an audience via the microphone; and
in response to determining that the speaker'"'"'s speech is not intended to be distributed to the audience via the microphone, performing one or more actions,wherein the analyzing comprises at least detecting a change in a manner of the speaker'"'"'s speech comprising at least a change in harmonics of the speech, and based on the detecting of the change, determining that the speaker'"'"'s speech is not intended to be distributed to the audience via the microphone,wherein one or more actions comprises at least generating a signal that indicates the microphone is turned on, the signal comprising echoing back to the speaker in different harmonics while the speaker is speaking, and turning off the microphone automatically, wherein the analyzing further comprises detecting a change in a voice volume of a speaker making the speech, a change in a topic of the speech, the method further comprising collecting visual cues comprising a change in distance between a speaker making the speech and the microphone, a change in location from where the speaker is making the speech, the audience entering into and exiting from the location,the detected change in the voice volume, the change in the topic of the speech, and the visual cues increasing a confidence score in determining to turn off the microphone.

9. A system for preventing unintended distribution of audio information, comprising:
-
a microphone; a processor operable to analyze audio data of a speaker'"'"'s speech received by the microphone and further operable to determine automatically whether the speaker'"'"'s speech is intended to be distributed to an audience via the microphone, and in response to determining that the speaker'"'"'s speech is not intended to be distributed to the audience via the microphone, the processor operable to perform one or more actions, wherein the processor is further operable to at least detect a change in a manner of the speaker'"'"'s speech comprising at least a change in harmonics of the speech, and based on the detecting of the change, the processor is further operable to determine that the speaker'"'"'s speech is not intended to be distributed to the audience via the microphone, wherein one or more actions comprises at least the processor automatically generating a signal that indicates the microphone is turned on, the signal comprising echoing back to the speaker in different harmonics while the speaker is speaking, and turning off the microphone automatically, wherein the processor detects a change in a voice volume of a speaker making the speech, a change in a topic of the speech, and visual cues comprising a change in distance between a speaker making the speech and the microphone, a change in location from where the speaker is making the speech, the audience entering into and exiting from the location, the detected change in the voice volume, the change in the topic of the speech, and the visual cues increasing a confidence score in determining to turn off the microphone. - View Dependent Claims (10, 11, 12, 13)
