Method and device for voice operated control
Methods and devices for processing and voice operated control are provided. The method can include performing a non-difference comparison between a first received sound and a second received sound, determining if speech exists based on the comparison, and transmitting or providing a decision that the speech is present to at least one among the device, a cell phone, a media player, or a portable computing device. Other embodiments are disclosed.
1. An earpiece, comprising:
an ambient microphone;
a speaker;
an ear canal microphone;
a memory that stores instructions; and
a logic circuit that executes the instructions to perform operations, the operations
comprising:
measuring ambient sound from the ambient microphone;
measuring internal sound received from the ear canal microphone;
comparing the ambient sound to the internal sound to determine if a user is speaking; and
controlling a mixing of an ambient signal and an internal signal to produce a mixed signal when it is determined that the user is speaking.
2. An earpiece according to claim 1 , further including the operations of:
extracting an audio signal of the user's voice from the mixed signal.
3. An earpiece according to claim 2 , further including the operations of:
analyzing the audio signal to determine a voice command; and
initiating an action in response to the voice command.
4. An earpiece according to claim 3 , where the voice command is to create an audio content wish list.
5. An earpiece according to claim 3 , where the voice command is perform at least one of the following actions with respect to an audio content list stored in the memory, purchase a song in the audio content list, delete a song from the audio content list, skip to the next song in the audio content list, add a song to the audio content list, and delete the audio content list.
6. An earpiece according to claim 3 , where the voice command is to adjust an audio content.
7. An earpiece according to claim 3 , where the voice command is to play audio from a radio station.
8. The earpiece according to claim 3 including a second ambient sound microphone.
9. The earpiece according to claim 8 , further including a sealing section.
10. An earpiece according to claim 9 , further including the operations of:
measuring the sound pressure level using the ear canal microphone.
11. An earpiece according to claim 10 , further including the operations of:
calculating the sound pressure level dosage of a user using the measured sound pressure level.
