Abstract
At least one exemplary embodiment is directed to a method and device for voice operated control. The method can include measuring a first sound received from a first microphone, measuring a second sound received from a second microphone, detecting a spoken voice based on an analysis of measurements taken at the first and second microphone, mixing the first sound and the second sound to produce a mixed signal, and controlling the production of the mixed signal based on one or more aspects of the spoken voice.
Claims14
An acoustic device, comprising:
- a first microphone configured to detect a first acoustic signal;
- a second microphone configured to detect a second acoustic signal;
- a processor operatively coupled to the first microphone and the second microphone, wherein the processor is configured to perform operations comprising:
- detecting a spoken voice based on an analysis of the first acoustic signal captured by the first microphone and the second acoustic signal captured by the second microphone, wherein the analysis of the first acoustic signal and the second acoustic signal is a coherence analysis, a spectral difference, or a combination thereof;
- determining, based on the analysis, a voicing level for the spoken voice, wherein the voicing level identifies a degree of intensity and periodicity of sound in the first and second acoustic signals;
- generating a voice activity flag declaring the presence of the spoken voice to a system after detecting the spoken voice;
- and a voice operated control configured to mix the first acoustic signal and the second acoustic signal to produce a mixed signal.
