Abstract: A method for constructing a speech recognition model includes obtaining a target keyword; determining a synonym group semantically associated with the target keyword; training a language model based on the target keyword and the synonym group; to obtain a target language model; generating a first decoding graph based on the target language model, where the first decoding graph indicates a plurality of decoding paths that satisfy a syntax constraint rule that is based on the target keyword and the synonym group; and determining the speech recognition model based on the first decoding graph.
