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: 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.
