Abstract
Disclosed are a speech recognition method capable of communicating with other electronic devices and an external server in a 5G communication condition by performing speech recognition by executing an artificial intelligence (AI) algorithm and/or a machine learning algorithm. The speech recognition method may comprise performing speech recognition by using an acoustic model and a language model stored in a speech database, determining whether the speech recognition of the spoken sentence is successful, storing speech recognition failure data when the speech recognition of the spoken sentence fails, analyzing the speech recognition failure data of the spoken sentence and updating the acoustic model or the language model by adding the recognition failure data to a learning database of the acoustic model or the language model when the cause of the speech recognition failure is due to the acoustic model or the language model and machine-learning the acoustic model or the language model.
