Embodiments of the invention include a device and a method for translating words spoken in one language to a graphic or audible version of the words in a second language. A planar array of three or more microphones may be placed on a portable device, such as a handheld computer or a personal digital assistant. The planar array, in conjunction with a signal processing circuit, defines a direction of sensitivity. In a noisy environment, spoken words originating from the direction of sensitivity are selected and other sounds are rejected. The spoken words are recognized and translated, and the translation is displayed on a display screen and/or issued via a speaker. |
