Abstract

PURPOSE: A mobile terminal for generating a ring-back tone by using voice synthesis and its method are provided to allow a user to discriminate his/her ring-back tone in a crowded place by generating a voice-converted ring-back tone. CONSTITUTION: A radio transmitter/receiver(11) transmits/receives a radio signal through an antenna. A calculating/controlling unit(12) drives and controls a mobile terminal. A CODEC(13) converts a signal received from the radio transmitter/receiver(11) into a voice through a decoding process to output it to a voice output unit(17) and a voice received from a voice input unit(20) into a signal through a coding process and then transmits it to the calculating/controlling unit(12). A storing unit(14) stores a program for driving the mobile terminal, a file system and a ring-back tone generated from a digital signal processor(16). A character/voice converter(15) converts a voice-combined sentence into a voice and outputs a synthesized sound. A DSP(Digital Signal Processor)(16) receives the synthesized sound, processes it to a signal, and mixes it with an existing bell sound to generate a new ring-back tone, and stores it in the storing unit(14). The voice output unit(17) outputs the voice received from the CODEC(13) or the ring-back tone stored in the storing unit(14). An LCD(18) outputs a screen. An input unit(19) receives a phone number, menu select information, a voice-synthesized sentence, a voice synthesis mode or an existing bell sound select signal. A voice input unit(20) receives a voice and transfers it to the CODEC(13).

WIRELESS COMMUNICATION TERMINAL AND METHODS OF SOUND COMMUNICATION USING SYNTHETICS {APPARATUS AND ITS METHOD FOR GENERATING RINGING TONE USING SPEECH SYNTHESIS IN WIRELESS TERMINAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication terminal for generating ring tones using speech synthesis, a method and a computer readable recording medium having recorded thereon a program for realizing the method.

In the present invention, a wireless communication terminal refers to a mobile communication terminal, a personal portable communication terminal (PCS), a personal digital terminal (PDA), a smartphone, a mobile terminal capable of wireless communication while being carried by an individual such as a next generation mobile communication terminal (IMT-2000). Say. In the following example, a mobile communication terminal will be described as an example.

In general, speech synthesis refers to a technology for converting text information or symbols into human speech, and combines various basic speech patterns through a mechanical device such as a computer to produce a voice close to the human voice. Such voice synthesis technology is expanding in application fields, and is used for computers, toys, electronic encyclopedias, and e-books.

Speech synthesis can be largely divided into restricted vocabulary synthesis and unlimited vocabulary synthesis. First, the limited vocabulary synthesis is a technique of generating a continuous speech by recording necessary pieces of speech in advance and connecting them, for example, an automatic response system (ARS). Unlimited lexical synthesis is a technique of synthesizing speech by receiving arbitrary sentences, and a text-to-speech (TTS) system belongs to it. Text-to-Speech (TTS) refers to a technology that converts a text input into a computer into a natural human voice.

On the other hand, as mobile communication terminals are rapidly spreading, demands of users using mobile communication terminals are increasing. In the past, the ring tone was provided only as a simple ringtone, but the demand for users who want to have their own unique ring tone is increasing, and in order to meet the demand, there is an increasing number of service companies that provide ring tone such as music or voice.

However, when a mobile terminal user wants to use a ring tone provided by a ring tone service company, there is an inconvenience in that the ring tone service company needs to download and use the ring tone already prepared by using the ring tone service company.

In addition, as the number of users of the mobile communication terminal increases, there are a large number of mobile communication terminals using the same ring tone. Accordingly, when a ringing tone sounds in a crowded place, the ring tone of the mobile communication terminal is recognized due to the same ring tone. There was a problem that could be confusing.

The present invention has been proposed to solve the above problems, and receives a text from a user, converts it into a voice, and mixes it with an existing ringtone to generate a ringtone using a voice synthesis for generating a new ringtone. It is an object of the present invention to provide a wireless communication terminal and a computer readable recording medium having recorded thereon a program for realizing the method.
