Description

Sound and speech recognition apparatus using sound and voice and a method for setting the same {Sound and speech recognition based bell signal generation apparatus and method}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring tone setting device and a setting method thereof, and more particularly, to a ring tone setting device and a setting method thereof for use in a device such as a mobile phone or a wired / wireless telephone.

When a call comes in, the phone rings and alerts you. That is, the ring tone provides the user with information that a call has been made. By the way, the spread of the telephone has been widespread, and in particular, the mobile phone is widely used, there is a problem in the use of such a ring tone.

Conventional telephones generally have the same tones for each product and are not distinguished from each other. Therefore, when the telephone rings in a crowded environment such as in an office or subway where several telephones are located, information that a telephone call is provided is provided. It is often difficult to distinguish which phone is ringing, which causes confusion.

For example, whenever you are at your coworker's desk in the same office, whenever you hear a tone, such as the ringtone on your phone, you should go to your seat and check to see if it is from you. In addition, when the mobile phone beeps in the subway, you can often see a lot of people checking to see if they are coming to you.

Recently, in order to solve this problem, there have been attempts to solve this problem by providing a method of allowing a user to select one by providing a plurality of beeps to a mobile phone, but basically, a limited number of beeps are shared by many subscribers. Since there are many similar beeps, and the same beeps are often used among people using the same product, in this case, the confusion may be more severe when the beeps used by other people's mobile phones are generated.

Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, the sound tone setting device using the sound and voice to solve the problem of beep confusion by the user actively generating the desired tone according to the preferences or needs And its setting method.

According to the present invention for achieving the above object, a microphone for receiving a melody, a frequency analysis unit and an energy analysis unit for converting the melody into a digital signal and analyzing the frequency component and the energy component of the signal, respectively; The voice recognition unit, the pitch recognition unit and the beat recognition unit for recognizing the voice, the pitch, and the beat of the input melody, and a basic melody generating unit for generating the melody passing through the recognition units as the basic melody, and the user in the basic melody There is provided a signal sound setting apparatus using a sound and voice including a rhythm addition unit for adding a rhythm, a tone and a tone to be specified, and a tone generating and storing unit for generating and storing a final signal sound.

In addition, according to the present invention for achieving the above object, the step of selecting the tone production mode, inputting the desired melody, performing the frequency and energy component analysis to recognize the height and length of the basic pitch and If there is an error in recognition, a method of setting a beep using sound and voice is provided, including correcting the error and adding a rhythm, a tone, a tone when the user selects it, and finally storing it.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a signal sound setting apparatus and a setting method using a sound and voice according to the present invention will be described in detail.

1 is a block diagram of a signal sound setting apparatus using sound and voice according to an embodiment of the present invention.

As shown in FIG. 1, the signal sound setting apparatus of the present invention receives a melody (including an instrumental sound or a recording and reproducing sound) directly spoken by a user into the microphone 11 and converts the signal into a digital signal. The frequency and energy components of the signal are analyzed by the frequency analyzer and energy analyzer 12, respectively, and the voice, pitch, and beat of the input melody are respectively recognized by the voice recognition unit, the pitch recognition unit, and the time recognition unit 13, respectively. By recognizing, the basic melody is generated by the basic melody generator 14.

That is, the user can enter "(1) a song he knows (e.g. school paper), (2) enter a melody without lyrics (e.g. ral ral ral ral ral), or (3) enter a melody as a commandment ( For example, “sol sol sol sol mee”, (4) inputting sound of playing other musical instruments or recordings of music ”through the microphone 11, the sound is transmitted to the basic melody generator 14 through a series of processes. The default melody is created. At this time, in the case of (3), the number of command lines is limited, and high recognition performance can be obtained by combining frequency component analysis results.

If there is an error in the basic melody recognition, the error correction process 15 undergoes an error correction process. The error correction displays the recognition result on the panel when there is a display panel as in a mobile phone, and designates the position, height and length of the sound to be corrected using the license plate button 18. In the case of the existing telephone, the position of the sound to be corrected is assigned to the license plate button 18 while playing the recognized result slowly, and the height and length of the sound are designated using the license plate button 18. In addition, when the user selects, the length of the input pitch is normalized by calculating the length of the optimal unit sound.

When the basic melody is formed, the rhythm specified by the user is added in the rhythm addition unit 16, or the tone and tone are adjusted in the tone and tone adding unit 17, and the final tone is generated in the tone generation and storage unit 19. Create and save it.

The beep generated and stored through this process generates a designated one of the stored beeps when an incoming call or an alarm sounds.

2 is a flowchart illustrating a signal sound setting method using sound and voice according to the present invention. As shown in Fig. 2, when a new tone is to be produced, the user first selects a tone production mode (S1), and directly utters a melody or inputs a sound by playing a musical instrument or playing a CD (S2). Then, frequency and energy component analysis is performed to recognize the height and length of the basic pitch (S3), if there is an error in the correction, correct it (S4), and add a rhythm, timbre, tonality when the user selects (S5). , S6), and finally store it in the storage device (S7). The user designates a stored ring tone as an incoming ring tone or an alarm tone and ends the tone production mode (S8).

3 is a diagram of a remote service system using the present invention. As shown in FIG. 3, the present invention is connected to a telephone system having a melody voice, a button input unit, and a ring tone storage unit to a service system implementing the functions shown in FIG. 1 through a communication network, according to the procedure shown in FIG. By rolling, a new tone can be created and used by the user.

As described in detail above, the apparatus for setting a beeping sound and its setting method according to the present invention and a setting method thereof may generate a beep sound desired by a user, unlike a method of selecting within a limited range of beeping sounds previously stored in a conventional telephone or the like.

In addition, the device and the setting method of the present invention, by generating a variety of signal tones unique to the user to increase the discrimination between the signal tones of other devices can be early to determine which phone or device tones are generated to reduce the signal confusion have.

In the above description, the technical idea of the sound setting apparatus and the setting method using the sound and voice of the present invention have been described with the accompanying drawings, but the exemplary embodiments of the present invention have been described by way of example and are not intended to limit the present invention.

In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
