摘要： Yes A keyword spotting method based on a neural network (NN) acoustic model is provided to tolerate for dynamically adding and deleting keywords by remapping new keywords as individual Acoustic Model Sequences. The method compares sequence matching in the phoneme spaces instead of directly in predetermined acoustic space. Therefore, the acoustic model cross comparison model is relaxed from global optimization to local minimum distance to each distribution.
