DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic information broadcasting system using roadside communication in a traffic control system.

[0002]

2. Description of the Related Art Roadside communication is one of means for providing traffic information in a traffic control system, and mainly transmits traffic information to a driver via a car radio by radio waves emitted from a transmitter installed on a road. It is. Roadside communication can use a car radio as a receiver, so no special equipment is required on the vehicle side, and because it is information transmission by hearing, the driver's burden on driving is lighter than a variable information board,
In addition, since the amount of information that can be provided is large, and a very limited service area can be formed, there is an advantage that local information necessary for a driver traveling at a specific point can be provided. .

Conventionally, when traffic information is broadcast to a driver using such roadside communication, an automatic sound piece assembling broadcast sentence by assembling a sound piece using an arithmetic processing unit is broadcasted or a voice input device is used. Broadcasting of either one of the broadcast texts arbitrarily recorded was performed.

[0004]

However, in the above-mentioned conventional traffic information providing device, when an attempt is made to provide a driver with a broadcast sentence that cannot be created by the automatic sound piece assembling, the automatic sound piece assembling broadcast is stopped and voice input is performed. Only the arbitrary recorded broadcast sentence is broadcasted by voice recording from the device, and the automatic sound piece assembly broadcast sentence and the arbitrary recorded broadcast sentence cannot be broadcast simultaneously.

The present invention solves such a conventional problem, and adds an arbitrary recording broadcast sentence that can be arbitrarily created to an automatic sound piece assembly broadcast sentence created according to predetermined conditions. It is another object of the present invention to provide a traffic information broadcasting system capable of broadcasting at the same time and further enriching traffic information.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides means for converting a sound recorded from a sound input device into a digital signal and inputting the digital signal to a storage device of an arithmetic processing unit, and a storage device. And a means for synthesizing two broadcast sentences based on the digital audio signal and the digital sound piece signal stored in the same into one broadcast sentence.

[0007]

According to the present invention, the present invention has the effect that both broadcasts can be broadcast at the same time without interrupting either of the broadcast by automatic sound piece assembly and the broadcast by arbitrary recording, which could not be performed conventionally. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a traffic information broadcasting system according to one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes arithmetic processing means for assembling a sound piece, reading and writing of a sound signal, 2 storage means for storing a digital sound signal, a digital sound signal and the like, and 3 for converting an input sound into an analog sound signal. The voice input means 4 for conversion is a voice quantization means for converting the analog voice signal obtained by the voice input means 3 into a digital voice signal, and the digital voice signal 5 processed by the voice quantization means 4 is stored in the storage means 2. Voice synthesizing means for synthesizing the stored digital sound piece signal and converting it into an analog voice signal; and 6, voice signal output means for outputting the analog voice signal obtained by the voice synthesizing means 5 to an antenna or a telephone line or the like. It is.

Next, the operation of the above embodiment will be described with reference to the operation flowcharts of FIGS. First, an arbitrary recorded broadcast sentence voice is input from the voice input means 3. The voice input means 3 converts the input arbitrary broadcast text voice into an analog voice signal. Next, the analog-converted arbitrary recorded broadcast sentence voice is converted into a digital voice signal by the voice quantization means 4. Next, as shown in FIG.
The arithmetic processing unit 1 transfers the arbitrary recorded broadcast sentence data converted by the audio quantization unit 4 to the storage unit 2 and stores it in the processes 1 to 14.

On the other hand, as shown in FIG.
Creates automatic speech unit assembly broadcast sentence data by combining the speech units stored in the storage unit 2 according to the conditions, and stores the data in the storage unit 2 (steps 21 to 23). Further, the arithmetic processing means 1 combines the automatic speech piece assembly broadcast text data stored in the storage means 2 with the arbitrary recorded broadcast text data and stores them in the storage means 2 (steps 24 to 27). Then, the automatic speech piece assembly broadcast sentence data and the arbitrary recorded broadcast sentence data thus combined are read from the storage means 2 under the control of the arithmetic processing means 1 and transferred to the speech synthesis means 5. ,
The voice synthesizing unit 5 converts the transmitted broadcast text data into an analog signal and outputs the analog signal from the voice signal output unit 6 to an antenna, a telephone line, or the like.

As described above, according to the above-described embodiment, the arithmetic processing means 1 for assembling the sound piece and reading and writing the audio signal, the storage means 2 for accumulating the digital sound signal and the digital audio signal, and Voice input means 3 for converting a voice into an analog voice signal, voice quantization means 4 for converting an analog voice signal obtained by the voice input means 3 into a digital voice signal, and digital voice processed by the voice quantization means 4 A voice synthesizing unit 5 capable of synthesizing the signal and the digital voice unit signal stored in the storage unit 2 and converting it into an analog voice signal, and outputting the analog voice signal obtained by the voice synthesizing unit 5 wirelessly or by wire. Audio signal output means 6
Therefore, there is an effect that it is possible to broadcast by combining both an arbitrary recorded broadcast sentence input from the voice input means 3 and an automatic sound piece assembly broadcast sentence created based on predetermined conditions.

[0012]

According to the present invention, as is apparent from the above-described embodiment, an arbitrary recorded broadcast sentence which can be arbitrarily created is added to an automatic sound piece assembly broadcast sentence created according to predetermined conditions. Since broadcasting can be performed at the same time, there is an effect that more substantial traffic information can be provided.
