Speech recognition method and system for power grid dispatching service

The invention discloses a voice recognition method and system for a power grid dispatching service, and belongs to the technical field of voice recognition, and the method comprises the following steps: S1, training a voice recognition model; and S2, multilingual speech recognition. According to the method, daily service telephone voice in the power grid dispatching service is collected and marked to form a local dialect, local mandarin and standard mandarin corpus data set, the three corpus data sets are used for training to obtain a corresponding voice recognition model, and then the voice recognition model is used for recognizing voice data of the power grid dispatching service. On the basis of obtaining an accurate recognition effect, the model parameter quantity is greatly reduced, the calculation resource and time cost of model training are effectively reduced, and meanwhile, the training resource is also effectively reduced.
