Let's look at how the algorithms work to capture and enhance the voice command for processing by the automatic speech recognition engine. The Stereo Acoustic Echo Canceller nulls the audio output from the device to enable reliable barge-in, and improves the signal to noise ratio. The Automatic Delay Estimation Control dynamically adjusts the audio reference signal for smooth, real-time barge-in. The Interference Canceller scans the soundscape of the room and nulls static point noise sources. Noise suppression removes background (or diffuse) noise. Automatic Gain Control balances the signal volume (making a quiet voice louder and vice versa). Finally, flexible interfaces and I/O structure enables the XVF3510 to be integrated easily into any solution.
