Abstract: In some examples, an acoustic input device includes a housing comprising a plurality of acoustic ports, and a plurality of single-port acoustic transducers within the housing to receive respective acoustic waves from an environment outside the acoustic input device through corresponding acoustic ports of the plurality of acoustic ports, where a first acoustic port of the plurality of acoustic ports is located on a first surface of the housing, and a second acoustic port of the plurality of acoustic ports is located on a second surface of the housing that is opposite the first surface. The acoustic input device further includes a controller within the housing to receive outputs of the plurality of acoustic transducers.

Abstract: Described herein is a technology related to a mobile device with a pair of stereo speakers. The mobile device has an orientation detection system that detects the orientation of the mobile device and a crosstalk cancellation system that performs crosstalk cancellation with complementary cardioid beams in response to the detected orientation of the mobile device. The mobile device also has an audio system that emits complementary cardioid sound beams from the speakers.

Abstract: In some examples, adaptive speech intelligibility control for speech privacy may include determining, based on background noise at a near-end of a speaker, a noise estimate associated with speech emitted from the speaker, and comparing, by using a specified factor, the noise estimate to a speech level estimate for the speech emitted from the speaker. Adaptive speech intelligibility control for speech privacy may further include determining, based on the comparison, a gain value to be applied to the speaker to produce the speech at a specified level to maintain on-axis intelligibility with respect to the speaker, and applying the gain value to the speaker.
