Description

Terminal and Method for Multi-call content-based keyword analysis service

The present invention relates to a terminal and method for a keyword analysis service based on multi-call content, which analyzes multi-call content to actively extract main keywords and provide it to a user.

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

Voice recognition in smartphones has been applied and used in various ways. The iPhone provided a voice command function so that simple commands such as running an app could be executed by voice, and Google provided a service for web search by voice.

In addition, a translation application that receives the user's voice input and speaks it in another language or an application that checks whether the user's pitch is correct are examples of using voice recognition technology.

Among these, the emergence of 'Siri' presented a new leap forward in speech recognition technology. Siri (Speech Interpretation and Recognition Interface) is a voice recognition service provided by Apple that first appeared in the iPhone 4S in 2011. Originally developed as part of the CALO project, which was developed for military use, it was developed with the commercialization of services. It was first provided as an application to the iPhone 3GS and enjoyed great popularity. In April 2010, Apple took over Siri exclusively, and Apple's Siri was born. Siri does not simply recognize voice, but works in conjunction with various applications to solve all tasks with a single voice command. In particular, it is equipped with an algorithm that can answer various queries based on a database center using dialog processing. Also, what made Siri so popular was the fact that it was possible to express yourself as freely as you would if you were talking to a person. It is a remarkable development compared to the existing voice recognition services that were successfully recognized only by speaking in a specified form of sentence.

Since then, voice recognition services such as Samsung Electronics' S Voice, LG Electronics' Q Voice, and Pentech's Smart Voice have appeared, and an environment for using smartphones more conveniently is being prepared.

However, the above-mentioned existing voice recognition services respond to the user's curiosity according to the terminal control according to the voice command (for example, call connection according to the voice command, alarm, schedule management, mail/text sending, etc.), and the voice command. Since it is specialized in functions such as search support for web browsers (eg, web browser connection, etc.), there is a limitation in that it is based on a manual operation according to a user's command.

Therefore, in order to solve the above-mentioned existing limitations, a technology for providing interest based on a call that analyzes the content of a call based on voice recognition during a call to actively extract and provide the interest of the caller is disclosed in Korean Patent Publication No. 10-1455924 It has been proposed as in

However, in the above-mentioned Registered Patent Publication No. 10-1455924, a description of a voice recognition keyword analysis service for the content of a call during a bilateral call is presented, but when a third-party call is entered during keyword analysis of a voice call based on the content of a bilateral call There was a problem that a solution for voice recognition keyword analysis service for multiple call contents could not be presented.
