Abstract: Techniques for improving speech recognition are described. An example of an electronic device includes an extracting unit to extract a reference spectral profile from a reference signal and a device spectral profile from a device signal. A comparing unit compares the reference spectral profile and the device spectral profile. A delta calculating unit calculates a delta between the reference spectral profile and the device spectral profile. A design unit designs a correction filter based on the computed delta.

Abstract: Audio beam forming control is described herein. A system may include a camera, a plurality of microphones, a memory, and a processor. The memory is to store instructions and that is communicatively coupled to the camera and the plurality of microphones. The processor is communicatively coupled to the camera, the plurality of microphones, and the memory. When the processor is to execute the instructions, the processor is to capture a video stream from the camera, determine, from the video stream, an audio source position, capture audio from the primary audio source position at a first direction, and attenuate audio originating from other than the first direction.
