In particular, the voice record search unit 320 is a word uttered with a pronunciation similar to the search word, and through comparison between words based on a word separation criterion, for example, a grapheme unit, a stem unit, a term unit, etc., the search term and a certain ratio or more You can search for synonyms with similarity.

The voice record search unit 320 may provide a filtering function according to the accuracy indicating the degree of similarity to the search word in the search process. For example, the voice record search unit 320 may provide search results by setting only words similar to a search term of 90% or more as a search target according to a user's request. can be excluded from

The search range may include not only a voice record but also a memo matched with the voice record, and the voice record search unit 320 may search for a word corresponding to the search term and a word similar in pronunciation to the search term within the voice record and memo. there is.

In addition, the voice record search unit 320 may allow a search according to a combination of words in the search process, that is, may support a search using a plurality of words. Search in units of words as well as search in units of sentences can be implemented.

The voice record search unit 320 may provide a search result for the voice record, and in this case, a word included in the search result in the voice record may be displayed separately from other words. For example, the voice record search unit 320 may display display elements (eg, highlight color, etc.) of words included in the search result differently according to accuracy. For example, words that match a search term at least 90% are highlighted in blue, words that are less than 90% similar to the search term are highlighted in light blue, and words that are less than 70% similar to the search term are highlighted in light blue, and words that are less than 70% similar to the search term are highlighted in blue. Words that are above can be highlighted in gray.

In step S430 , the voice record correction unit 330 may correct at least one word included in the search result into another word. For example, the voice record correction unit 330 may correct a word included in the search result into a word input as a search word or a word newly input by the user. In this case, the voice record correction unit 330 may collectively modify all of the words included in the search results or selectively modify some of the words included in the search results according to the user's selection.

Accordingly, the processor 220 may provide a search function including words uttered similarly to the search term in the voice record in which the voice is converted into text, and may also provide a correction function to replace the searched word with another word. can provide
