Abstract
A speech data recognition method, apparatus, and server are for distinguishing regional accent. The speech data recognition method includes: calculating a speech recognition confidence and/or a signal-to-noise ratio of the speech data, and screening a regional speech data from the speech data based on the speech recognition confidence and/or the signal-to-noise ratio of the speech dat; and determining a region to which the regional speech data belongs based on a regional attribute of the regional speech data. The regional speech data are automatically recognized from the mass speech data by calculating the speech recognition confidence, the signal-to-noise ratio of the speech data or the combination thereof, thereby avoiding manual labeling of the speech data and enhancing the efficiency of the speech data processing.
