Method and device for recognizing speech based on chinese-english mixed dictionary

A device for recognizing a speech based on a Chinese-English mixed dictionary, comprising:

• a memory;
• a processor;
• and
• computer programs stored in the memory and executable by the processor,
• wherein when the processor executes the computer programs, a method for recognizing a speech based on a Chinese-English mixed dictionary is performed, the method comprising:
• acquiring a Chinese-English mixed dictionary marked by an International Phonetic Alphabet IPA, wherein, the Chinese-English mixed dictionary comprises a Chinese dictionary and an English dictionary revised by Chinglish;
• by taking the Chinese-English mixed dictionary as a training dictionary, taking a one-layer Convolutional Neural Network CNN and a five-layer Long Short-Term Memory LSTM as a model, taking a state of the IPA as a target and taking a Connectionist Temporal Classifier CTC as a training criterion, training the model to obtain a trained CTC acoustic model;
• and
• performing a speech recognition on a Chinese-English mixed language based on the trained CTC acoustic model.

A non-transitory computer readable storage medium, configured to store computer programs, wherein when the computer programs are executed by a processor, a method for recognizing a speech based on a Chinese-English mixed dictionary is performed, the method comprising:

• acquiring a Chinese-English mixed dictionary marked by an International Phonetic Alphabet IPA, wherein, the Chinese-English mixed dictionary comprises a Chinese dictionary and an English dictionary revised by Chinglish;
