An apparatus includes an interface for microphones, a separated source processor configured to analyze channels from the microphones, and a voice activity detector (VAD) circuit. The VAD circuit is configured to generate a voice estimate (VE) value. The VE value is to indicate a likelihood of human speech received by the microphones. Generating the VE value includes adjusting the VE value based upon a delay between two of the microphones. The VAD circuit is configured to provide the VE value to the separated source processor.

Method for robust directed source separation

The present disclosure describes a communication device and server configured to provide a user a relative event impact map display depicting a plurality of items impacted by an event or a portion of a network impacted by the event. The network can not only be a supply and/or logistics chain but also a computer network, a telecommunications network, transportation network, and power grid.

Method for determining and providing display analyzing of impact severity of event on a network

An audio device and a method thereof are provided. The method is adopted by an audio device to detect a voice, wherein the audio device is coupled to a host device. The method includes an acoustic conversion circuit converting an acoustic wave into an analog audio signal; an analog-to-digital converter (ADC) converting the analog audio signal into digital audio data; a first-level voice detection circuit detecting voice activity in the analog audio signal; a second-level voice detection circuit detecting a beginning syllable of a key phrase in the digital audio data when the voice activity is detected in the digital audio data; and a third-level voice detection circuit detecting the key phrase from the digital audio data only when the beginning syllable of the key phrase is detected in the digital audio data.
