摘要： A portable terminal has a network interface that receives a set of instructions having a sequence of at least one location and audio properties associated with the at least one location from a server. An audio circuit receives audio signals picked up by a microphone and processes the audio signals in a manner defined by the audio properties associated with the at least one location. A speech recognition module receives processed signals from the audio circuit and carries out a speech recognition process thereupon.

摘要： Provided herein are a multi-microphone system and method including a controller, a plurality of transducers each operable within a unique sensitivity range, and corresponding microphone units. The controller receives a sound signal output from a first microphone unit that corresponds to a microphone unit having a transducer with the highest sensitivity. The controller analyzes the sound signal output to identify a first parameter of the sound signal output and determines if the first parameter satisfies pre-defined criteria. In an instance in which the first parameter satisfies the pre-defined criteria, the controller outputs the sound signal output of the selected first microphone unit as the output of the multi-microphone system. Otherwise, the controller receives a sound signal output from a second microphone unit comprising a corresponding transducer with a sensitivity less than the first microphone unit but greater than remaining transducers.
