Voice identification method and apparatus

The invention provides a voice identification method and apparatus. The voice identification method comprises the following steps of receiving a voice signal; performing decoding on the voice signal according to a pre-established acoustic model, a linguistic model and a decoding network, and dynamically adding a blank unit in the decoding process to obtain an optimized decoding route with the added blank unit, wherein the acoustic model is obtained based on connectionist temporal classification training; the acoustic model comprises a basic pronouncing unit and the blank unit; the decoding network consists of multiple decoding routes formed by the basic pronouncing unit; and outputting the optimized decoding route to be used as the identification result of the voice signal. According to the voice identification method, the accuracy of voice identification can be improved, and the decoding speed in the identification process is improved.
