Abstract: The various implementations described herein include methods, devices, and systems for automatic audio equalization. In one aspect, a method is performed at an audio device having one or more processors, memory, and a plurality of device interface elements, including one or more speakers and a plurality of microphones. The method includes: (1) detecting a change in orientation of the audio device from a first orientation to a second orientation; and (2) in response to detecting the change in orientation, configuring operation of two or more of the plurality of device interface elements.

Abstract: A user is alerted to context-based transactional information under which products are to be transacted at a point-of-transaction site by a speaker on an electro-optical reader. The speaker announces, as an audible message, to the user a detailed context under which each product identified to the reader is to be transacted. The audible message is broadcast as a sound wave either corresponding to a pattern of original speech, or to a sound effect. The detailed context can, for example, be a reminder to deactivate an electronic article surveillance (EAS) tag associated with each identified product, or a reminder that the identified product is on sale.
