Classification: CPC G | IPC G

Claim 16:
17. A speech recognition apparatus comprising:
a voice interface configured to receive an input speech from a user; and
a processor configured to:
determine a first score of candidate texts based on the input speech, wherein the first score of the candidate texts is an output from a neural network-based decoder;
determine a weight for an output of a language model, selected from among a plurality of language models based on a type of the input speech, based on the type of the input speech, and context information associated with the input speech, using a neural network-based weight determiner,
wherein the neural network-based weight determiner is configured to receive extracted features and the context information through an input layer of the neural network-based weight determiner, and the extracted features are extracted from the input speech;
apply the weight to a second score of the candidate texts output from the language model to obtain a weighted second score;
select a target candidate text from among the candidate texts based on the first score and the weighted second score corresponding to the target candidate text; and
recognize the target candidate text to correspond to a portion of the input speech.
