DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice information transmitting device. It is intended that many individual pieces of information can be efficiently transmitted to unspecified recipients by voice.

[0002]

2. Description of the Related Art Radio broadcasting has long been used as a means for transmitting audio information to an unspecified number of people. However, radio broadcasting has the following problems. (A) It is not possible to automatically select and listen to only necessary information (for example, a market price of a specific stock in a stock market). (B) In the radio receiver, the processing from the reception of a radio wave to the output of a sound wave is performed without temporal expansion or contraction or delay. For this reason, it was necessary to listen to the radio in time for the broadcast.

A system in which individual information is transmitted from one center and received by an unspecified small number of people is disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 59-198034. It deals with the integration of code and information. The code is a classification of the information content. The center sends such wireless information at random. The receiver (user) always carries a portable receiver, and specifies the type of information desired by a code. The center transmits various kinds of information with codes at random. The receiving side receives only the information of the required code, emits a sound indicating the reception, alerts the user, and displays the information on a small display board. The user sees this and can read the latest information visually.

[0004] This can be sent to an unspecified small number of recipients who need individual information. In this respect, the disadvantage (a) is solved. However, the number of information that can be sent is one, and it is displayed at the same time as reception. So you have to look at the sign immediately. If it is late, the next information comes in and overlooks the previous information. That is, there is no function of storing information until an arbitrary time.

The above-mentioned disadvantage (b) has not been solved.
Since you do not know what information is sent from the center and when, always carry a portable receiver and always be careful. The information output initiative is on the center side,
This is inconvenient because there is no user. In addition, since text is displayed on the display board instead of being output by voice, only short phrases can be transmitted. Long-length information cannot be transmitted, and information transmission efficiency is low.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention selects necessary information at a receiving section, automatically accumulates the information, and stores the information at any time convenient for the user. In addition, the present invention provides a voice information transmission device that can be heard by a user's instruction.

[0007]

According to the present invention, there is provided an audio information transmitting apparatus comprising: a classification code for classifying information contents; and an information code corresponding to a text which is a string of characters or symbols representing audio information. An apparatus for receiving a signal transmitted from a transmission unit by radio by transmitting a signal as a digital signal on a carrier wave, an antenna for capturing a radio signal, a radio receiver for demodulating a radio signal, and a signal obtained here A digital code demodulator for converting a digital signal, a classification code memory for storing one or more classification codes specified in advance corresponding to the type of information desired by the user, and the output of the digital code demodulator. A selection circuit that selects only information signals having a classification code stored in the classification code memory of the storage device, a storage unit that stores all information signals selected by the selection circuit, Scanning unit that scans the information code corresponding to the text stored in the storage unit when given, and speech rule synthesis that converts the information code sent from the scanning unit into character text and further converts it into an electric signal corresponding to voice And a container.

[0008]

According to the present invention, there are one or a plurality of transmitting units and an unspecified number of receiving units, during which a lot of individual information is transmitted and received. The direction of transmission is one-sided. The transmitting unit attaches a classification code indicating the type of information to all information and transmits the information. The receiving unit specifies in advance the type of information required by the user by using a classification code. The receiving unit automatically stores all the information of the classification code. Do not convert to speech immediately.

When the user gives an instruction to the receiver when it is convenient, the storage section is scanned to read out the stored information, converted into voice, and sent out from the speaker as voice. As a result, the user can collect and hear necessary information in a short time. Information reception and retrieval time are performed independently. The user can freely listen to the accumulated information at a convenient time.

[0010]

FIG. 1 is a schematic diagram illustrating the configuration of the present invention.
A digital information signal a including a classification code and an information code is transmitted from the transmission unit 1 via the transmission path 2. The classification code is a search code for classifying information contents. It consists of a symbol indicating that it is a classification code, followed by a finite fixed number of digit strings. For example, a slash symbol "/" and ten digits can be used. The information code corresponds to text, which is a sequence of characters and symbols representing audio information. Because it is digitally encoded text,
It is composed of 1 "and" 0 ".

[0011] The characters and symbols forming the text include:
There are katakana, accent marks, punctuation marks, numbers, kanji, kana, alphabets, phonetic symbols, etc. The text is
It may be composed of only katakana, accent marks, punctuation marks, numbers, and alphabet symbols. Digitally encoded text is an information code. One information signal a is created by the information code and the classification code. There is always a classification code at the head of the information signal. When the classification code is detected, it is understood that a new information code starts following this. Examples of information codes and corresponding information contents are shown below.

[Example 1] 0000000010034 Midousujido ▼ Ori, Kitamu Kiwa, Juteide ▼

[Example 2] / 00120000000000 Nishinihon II (abbreviated below)

Here, ▼ is an accent symbol, and △ is a blank symbol. In Example 1, 0000000010034 is a classification code representing traffic information on Midosuji. In Example 2 /
001200000 is a classification code indicating the general weather condition nationwide. Following these, the katakana sentences are text.

On the other hand, the receiving section 3 has a selector 4 composed of a CPU or the like, a storage 5 composed of a semiconductor memory or a floppy disk, and a speech rule synthesizer 6. The meaning of the classification code is predetermined. In each receiving unit 3, only the necessary classification code is registered in the classifier 4 in advance. The classifier 4 sequentially compares the registered classification codes with the classification codes of the information signals sent one after another. Only the information signal whose classification code matches the registered classification code is selected and stored in the storage 5.

An information signal having a classification code that does not match the registered classification code is discarded. For example, if only a classification code / 001200000 is registered in a certain receiving unit, all information signals having this classification code are stored. Therefore, in Example 2, "Tenkiga ▼
Select and accumulate the information signal corresponding to the text "."

When receiving an instruction from the receiver, the speech rule synthesizer 6 converts the stored information code into text and outputs it as speech. The receiving unit can obtain only pre-registered voice information from various information such as stock market, traffic information, and general weather.

[Configuration of Transmitter] Next, the configuration of the transmitter will be described. There is one or a plurality of transmission units. If there are a plurality, the transmission time is divided and transmission is performed using carrier waves of the same frequency. All data to be transmitted is a data base.
Assume that they are stored in the storages 22, 22, ',.
These include, for example, a weather information database of the Meteorological Agency, a traffic information database of the police, or a stock price database of the stock market.
And so on. In addition, the product information of the part
It can be a database. The sender inputs an instruction of a transmission content to be transmitted to the transmission content creation unit 21.

In accordance with the instruction, the transmission content creation unit 21 extracts necessary information from the databases 22, 22 ',. For example, if the weather forecast information is to be sent, the database of the Meteorological Agency is searched to obtain the text of the weather forecast. The voice information corresponding to the weather forecast is added to this and sent to the transmission content memory 25. Thus, the transmission content memory 25
, Information signals composed of a text and a classification code are successively stored. The surrounding text is irrelevant in content. A number of independent texts are stored over time.

The memory scanning unit 26 includes a transmission content memory 25
And sends an information signal composed of a classification code and text to the digital code modulator 28. Digital code modulator 28
Is for sequentially converting an information signal, which is a digital signal, into an analog signal. It is known as a function such as a modem. The conversion into an analog signal is for wireless transmission. A carrier having a constant frequency needs to be modulated (AM, FM) by a digital signal.

For example, a modulated wave of 2100 Hz is generated for a digital signal "0" and a modulated wave of 1300 Hz is generated for a digital signal "1". The length of one signal may be about several msec.
The carrier is modulated by the modulated wave. The modulated carrier is emitted as radio waves from the wireless transmitter 29 and the antenna 8 into the atmosphere. Here, the transport means uses radio waves. However, the present invention is not limited to this, and may be a cable broadcast.
In the case of a wire, an electric wire, an optical fiber cable or the like can be used. It can also be sent as a digital signal.

In any case, the voices are not transmitted as they are, but the characters and symbols that are the source of the voices are converted into digital signals, which are transmitted substantially as digital signals.

[Configuration of Receiving Unit] The configuration of the receiving unit will be described with reference to FIG. The radio wave is captured by the antenna 9 and received by the wireless receiver 31. The resulting analog signal is converted back to the original digital signal by the digital code demodulator 32. It consists of a classification code and an information code. The classification code of the information desired by the user is registered in the classification code memory 34 in advance. This may be one or plural.

The sorting circuit 33 receives the received classification code,
The classification codes registered in the classification code memory 34 are sequentially compared. If there is a match, this information signal is selected. If they do not match, this information signal is discarded. The selected information signal is sent to the storage unit 36, and both the text and the classification code are stored therein. This selective accumulation is automatically continued forever as long as there is information having a matching classification code. Since the information is digitized, the memory capacity for storage is small. Thus, the information signals having the registered classification codes are sequentially stored in the storage unit 36. The selector 4 (FIG. 1) corresponds to a combination of the selector 33 and the classification code memory 34 shown in FIG. As described above, the sorter 4 can be implemented by a CPU, but in this case,
A sorting circuit and a classification code memory are implemented by the CPU.

The user need not always be beside the receiving unit. The receiving unit automatically repeats sorting and storing. When convenient and necessary, the user gives an output instruction to the receiving unit. When receiving an output instruction from the user, the scanning unit 37 extracts all the text from the storage unit 36 and sends it to the display unit 38 and the speech rule synthesizer 6.

The speech rule synthesizer converts a text into speech. For example, in the case of an English sentence, a DE
C talk and PRO of US-based SPEECH PLUS
SE2000 or the like can be used. In the case of Japanese katakana sentences, TSS-500C of Toyo Tsushinki can be used. Since the information is converted into voice, even long information can be easily expressed. In addition, since it is heard differently from reading, it can be heard even when the user is working or in any other state.

The text converted to speech is output from an electroacoustic transducer (speaker 40). The user can know the information by listening to the voice. As the electroacoustic transducer, an earphone can be connected to a terminal for outputting an electric signal of the speech rule synthesizer, in addition to the loudspeaker. The display unit 38 displays characters on the drawing. For example, a CRT device is used. Thus, a visual expression may be used in addition to the audio expression. However, the visual representation may be omitted as it requires a separate display device

[0028]

(1) The present invention relates to a configuration of a receiving section for receiving voice information. With such a configuration, the selective storage of the information content can be automatically performed by the receiving unit. The transmission section does not need to select information contents.
Since the transmission is simply performed irrespective of the difference in the information content, the configuration of the transmission unit is simplified.

(2) Since information is automatically selected and stored in the receiving unit, only necessary information can be listened to when necessary. It is much more efficient in obtaining information than radio broadcasting.

(3) Audio is transmitted as it is (for example, PCM
Rather than modulating, we send the characters and symbols that are the source of speech as digital signals. Therefore, a very large amount of information can be transmitted with a small transmission capacity. For example,
56 kbit / s when voice is transmitted as PCM data
The amount of information is about ec. According to the present invention, the amount of information required for voice transmission is 80 bits / sec at a normal speaking speed.
Becomes However, one character is represented by 8 bits.
As the information amount, a capacity of 1/700 is sufficient. (4) Since a large amount of information can be transmitted, the contents can be enhanced and diversified.
