Method, medium, and system detecting speech using energy levels of speech frames

摘要

A speech recognition method, medium, and system. The method includes detecting an energy change of each frame making up signals including speech and non-speech signals, and identifying a speech segment corresponding to frames that include only speech signals from among the frames based on the detected energy change.

主权项

1. A speech recognition method, comprising:
detecting, using at least one processing device, energy changes between a plurality of frames distinguishing portions of a signal, each of the plurality of frames having time lengths less than a whole time length of the signal; and identifying speech segments and/or non-speech segments from the plurality of frames based on the detected energy changes between the plurality of frames by assigning a predetermined weight to a segment in which an energy level of a respective frame is changed and when an energy difference exists between two neighboring frames.
