11. A phone for performing speech keyword retrieval, comprising a processor and a non-transitory storage medium accessible to the processor, the phone configured to perform acts comprising: configuring language models, and at least two of the language models each comprises a recognition model and a decoding model that corresponds to the recognition model; extracting a speech feature from to-be-processed speech data, and sending the extracted speech feature; determining which of the recognition models has a highest language matching rate by performing, using the recognition models, language matching on the extracted speech feature; identifying the decoding model that corresponds to the determined recognition model, and sending the extracted speech feature; decoding the extracted speech feature by using the identified decoding model, obtaining a word recognition result, and sending the word recognition result; and matching a keyword in a keyword dictionary and the word recognition result with each other, and outputting a matched keyword on a display of the phone.
