Description

Technical Field [0001] The present invention relates to a terminal, a server, a method, a recording medium, and a computer program for providing key keyword information and a background image based on a call content,

The present invention relates to a terminal, a server, a method, a recording medium, and a computer program for analyzing a call content based on voice recognition during a call to provide a main keyword information necessary for a caller and a background image related to the information.

Speech Recognition refers to a technology in which a computer analyzes voice and converts it into character data. It is one of the technologies that is attracting attention because it can input information quickly and easily by voice without using a separate input device such as a keyboard.

Speech recognition has been used in various ways in smart phones. The iPhone provides a voice command function that allows users to execute simple commands such as running apps by voice, and Google provides a service for searching the web by voice.

In addition, a translation application that uses a user's voice to speak in another language or an application that checks the user's pitch is also an example of using speech recognition technology.

In the meantime, the appearance of 'Shirai' presented a new leap forward in speech recognition technology. Siri (Speech Interpretation and Recognition Interface) was first introduced in iPhone 4S in 2011 as a speech recognition service provided by Apple. Originally developed as a part of the commercial CALO project developed for military use, it was first developed as an application on the iPhone 3GS and became popular. In April 2010, Apple acquired Shirley exclusively and the current Apple Shiri was born. The characteristics of the series are not simply recognizing the voice, but it can solve all the tasks with one voice command in conjunction with various applications. It also provides the learning recognition function and the function to increase the recognition rate by learning the user's voice, In particular, it has an algorithm that can answer various queries based on database center using dialog processing. Also, the reason that Shiri got popular was that he could express freely as he could talk with people. It is a remarkable development compared to the fact that existing speech recognition services have been successfully recognized only in the form of a sentence.

Since then, voice recognition services such as Samsung's S-Voice, LG Electronics' Q-Voice, and PENTEC's Smart Voice have appeared, making it easier to use smartphones.

However, the conventional speech recognition services described above can be applied to terminal control (e.g., call connection according to a voice command, alarm, schedule management, mail / text sending) according to a voice command, (For example, connection to a web browser, etc.), it has a limitation that it is based on passive operation by the user's command.
