The present invention relates to an automatic speech recognizer and a speech recognition method using a keyboard macro function, the automatic speech recognition method using the keyboard macro function comprising the steps of: a transcriptional data generation unit generating transcriptional data on the basis of speech data input through a microphone; a tagging unit that, when a word to be tagged that is preset for executing a macro function is included in the generated transcriptional data, tags the generated transcriptional data, and performs conversation and storage; and displaying the generated transcriptional data in a space, in which data can be input, on a practical program in a virtual keyboard input manner. The automatic voice recognizer and the voice recognition method can provide the following effects: voice can be directly recorded in a text form under the condition that an electronic medical record, a paper operation record and the like are difficult to manually record when an actual patient is diagnosed and treated on a medical site, and convenience is provided.
