First Claim
1. A computer-implemented method for generating a grapheme-to-phoneme model based on artificial intelligence, performed by one or more computing devices and comprising:
- during performing a grapheme-to-phoneme conversion training by a neural network on each word in training data, screening nodes in a hidden layer of the neural network randomly according to a preset node ratio so as to obtain retaining nodes for training each word;
training each word with a sub-neural network corresponding to the retaining nodes and updating a weight of each retaining node of the sub-neural network;
performing a mean processing on the weights of the retaining nodes of respective sub-neural networks, so as to generate the grapheme-to-phoneme model; and
adjusting the number of layers in the neural network, the number of nodes in each layer and the preset node ratio according to the number of words in the training data.
