The directivity of a loudspeaker describes how sound produced by the speaker varies with angle and frequency. Low-frequency sound tends to be relatively omnidirectional, while high-frequency sound tends to be more strongly directional.

For example, high-frequency sounds may appear to be muffled in one ear, compared to the other. A multi-speaker sound system can employ binaural directivity compensation, which can compensate for directional variations in performance of each speaker, and can reduce or eliminate the difference in volume or spectral content between the left and right ears of a listener. The binaural directivity compensation can optionally be included with spatial audio processing, such as crosstalk cancellation, or can optionally be included with loudspeaker equalization.

Predicting and learning users' intended actions on an electronic device based on free-form speech input. Users' actions can be monitored to develop a list of carrier phrases having one or more actions that correspond to the carrier phrases. A user can speak a command into a device to initiate an action. The spoken command can be parsed and compared to a list of carrier phrases. If the spoken command matches one of the known carrier phrases, the corresponding action(s) can be presented to the user for selection. If the spoken command does not match one of the known carrier phrases, search results (e.g., Internet search results) corresponding to the spoken command can be presented to the user. The actions of the user in response to the presented action(s) and/or the search results can be monitored to update the list of carrier phrases.

A keyboard device and a musical sound emission method are provided. A top lid is formed into a hollow structure including a lower plate and an upper plate facing the lower plate. Since vibrating bodies are fixed to an inner surface of the lower plate, the vibrating bodies can cause the lower plate to vibrate and thereby emit musical sound generated through the vibration from an outer surface side of the lower plate to the outside. On the other hand, the musical sound emitted from an inner surface side of the lower plate is blocked by the upper plate, and it is thus possible to curb mutual cancelation of musical sound in opposite phases emitted from each of the inner surface and the outer surface of the lower plate. Therefore, it is possible to efficiently emit musical sound to the surroundings of the top lid.
