(57) Abstract:

The invention relates to methods of reception of voice messages and can be used when fontanarrosa. The invention consists in the fact that optional form code of query rules, found sounds and their combinations with the last priority codes removes from storage devices long-term storage without destroying the information in the form of corresponding symbols and query rules verbatim letters build words and phrases and record has already built in the codes of the images is performed in two feathers, one of which depict the main line of the notes, and the other put the symbols of words, phrases, and intervals between them shifted accordingly to the rules relative to the main line of stave consistent with the scale. The technical result is achieved by the use of the invention is to provide opportunities automate monasterii voice messages. 1 C.p. f-crystals, 4 Il., table 1.

The invention relates to methods of reception of voice messages and can find primary use wherever justified the use of monasterii.

Susesi speech, for example on a tape recorder, it is impossible sound information quickly transfer it visible image. It requires additional labor costs, time and resources.

Therefore, regardless of the voice recording on the tape is used as the usual shorthand, and fontanari, which is widely distributed in real time, as the most efficient one. One page vonostingroup.com text replaces the 10 pages of printed text, which reduces the process of transferring information, for example, when using space communication.

However, the process of shorthand and monasterii not avtomatizirov and, therefore, not effective enough.

We propose a method of ponasterone to automate this process. The method is implemented using methods of monasterii described in the book of O. G. Alexandrova "Footerarea", ed. Changes of moldoveneasca", Chisinau, 1968 and enhanced by one of the authors, L. J. King, using the latest advances in technology.

The invention allows to automatically convert the audio message in different languages in phonetenormin that can be very useful when conducting international is whether the publishers, records management (concise account, reducing the amount of documentation), reduce the staff of vonostingroup.com, reducing the number of persons permitted to confidential information, is provided by the centralized collection reporting information using stationary equipment, etc. When using the known recording devices (e.g., tape recorders) in the mode of accumulation of the audio information, the invention allows to significantly accelerate the process of obtaining phonetenormin when reading information from these devices at a higher speed.

Currently, there are various ways of recording sound and suitable for recording voice messages, as well as recording recorders to disk, and even with the use of laser, the recording on the tape, but they are the technical nature far from the proposed method and problems of automatic monasterii not solve (see "Technology magnetic recording" IL, M, 1962, edited by M. A. Rosenblat).

The known method of a digital magnetic recording audio signals, described in the patent N 1103809 from 07.08.81,, CL C 11 B 5/09, Sony Corporation (Japan).

This method implements the preservation of information, but it does not contain the automatic vonostingroup.com recording in real time.

Currently, intensive work is underway to communication with the computer. The described method of communicating with a computer using speech, including speech to the signal of the sound signal processing using a computer, with its input, broken at intervals by computing the spectrum of the words (digits), the comparison of the obtained spectra with spectra recorded individual words and fixation of their matches (see Digital processing of speech signals. L., Rabiner, R. C. Schafer. M.: Radio and communication, 1981 , S. 456, Fig. 9.22). The book describes the latest achievements in the USA, the USSR, Japan, these studies are bibliographic material. The described method does not distinguish individual sounds, and cannot be used for automation of monasterii voice messages.

The prototype of the claimed method is a method of ponasterone, including the selection of sound sequences with their symbols, the control of the detected sounds, breaks, drum sounds, the execution of the construction of words and phrases found sounds and their combinations with precedence rules verbatim letters, which is described in the book "Footerarea" Oh, Alexandrova, Chisinau, 1968, S. 12-38.

The disadvantage of this method is the prototype of the m fast short-time Fourier transform, processor spectra with a prior record in a storage device for long-term storage of graphic symbols simple sounds, their spectra and symbols in combinations of 2 to 6 sounds and rules verbatim letters. Furthermore, the method does not include operations on the construction of words, phrases and their registration which hampers its applicability to automate the process of ponasterone.

Common features of the prototype method and the proposed method are:

how ponasterone, including the selection of sound sequences with their symbols, the control of the detected sounds, breaks, drum sounds, the execution of the construction of words and phrases found sounds and their combinations with precedence rules verbatim letters.

In the implementation of the proposed method is achieved technical result - automation of monasterii. This technical result in the implementation of the proposed method is achieved by the known method of ponasterone, including the selection of sound sequences with their symbols, the control of the detected sounds, breaks, drum sounds, running build sprechen sound is converted into a signal, find simple signal sounds using short-time fast Fourier transform processor and processing the spectra in this advance in the storage device enter long-term storage of graphic symbols of sounds, their spectra and the characters of simple combinations of sounds and rules of shorthand writing, and when fontanarrosa speech additionally generate request code rules, found sounds and their combinations with the last priority codes are removed from storage devices long-term storage without destroying the information in the form of corresponding symbols and query rules verbatim letters build words and phrases and record has already built in the codes of the image is performed in two feathers, one of which depict the main line of the notes, and the other put the symbols of words, phrases, and intervals between them shifted accordingly to the rules relative to the main line of stave consistent with the scale, with the combination of simple sounds is from 2 to 6 sounds.

Detection in speech signal simple sounds emitting sound combinations with symbols, enable the use of all the entered graphical oboznov and phrases from individual characters, that provides automatic conversion of voice messages in the verbatim text of phonetenormin. This conversion can be performed without interference in the process of converting and reception, i.e. automatically in the regime close to its execution in real-time. That ensures the efficiency of the proposed method.

The above and the fact that in the analysis of technical and patent literature is not detected combinations of essential features, the same combinations of essential features of the claimed method, allows to conclude that the proposed method is new, involves an inventive step and is industrially applicable, i.e., has the patentability criteria.

The structure of the operations of the method shown in Fig. 1, where:

1. Converting speech sounds into a signal.

2. Detection of common sounds and their encoding.

3. The selection of sound combinations with characters.

4. The input and storage of characters.

5. Construction of words and phrases.

6. Control sounds.

7. The input and storage rules.

8. Record.

The scheme implements the method of the device is similar to the supply common sounds and their coding the exit code detected sounds associated with the input device selection sound combinations with the characters, the other output of the detector sounds simple input control unit sounds, the output codes of the detected sounds and their combinations device selection sound combinations associated with the address input of the input device and store characters, the output of which is connected to the first input of the Builder of words and phrases, the output control unit of the sounds associated with the second input of the Builder of words and phrases, the second output control unit sounds associated with the input address input device and storage rules, the output of which is connected with the third input of the Builder of words and phrases, output, which is connected to the input of the recorder.

In Fig. 2 shows typical types of spectra.

On coordinate axes deferred: the vibration amplitude A and frequency f (kHz) with lifts F1, F2, F3 corresponding formant frequencies given range vocalized (vowel) sound, and with the peak of the spectral density B shows the spectrum fricative sound. Formants vocalized sound F1 = 300 Hz, F2 = 870 Hz, F3 = 2240 Hz. The sound of "Y" (wax) B - pole spectral density fricative sound, which is characterized by three values of the frequencies f1, f2, f3; f2 corresponds to 0.2 from the peak level.

In Fig. 3 shows the duration of speech sounds:

C - unstressed vowel sound, D is the vowel under stress, E is the consonant sound.

In Fig. 4 explains the construction of words or phrases in shorthand characters using the rules:

1 - phrase in the form of a temporal sequence of sounds, letters;

2 - found simple speech sounds in a sequence of symbols;

3 - character replacement simple sounds on the character group of sequences or groups of sounds;

4 - construction of words and phrases according to the rules.

The method includes the following operations. Converting speech sounds into a signal produced by the microphone with amplifier, the bandwidth of frequencies in the amplifier limit in the range from 200 Hz to 3 kHz, for example, by applying filters.

Detection of common sounds and their coding is performed with the advanced signal processing of the sound of speech in the form of short-term fast Fourier transform, which is performed with discrete entering information, for example, with a frequency of cycles from 7 to 8 kHz, limited by ADC conversion with compute the spectrum of secondary energy in the form of frequency combs, for example, have the live with the definition of formant frequencies to determine vowel sounds and the determination of the frequencies of the zeros and poles of the spectral density of energy for consonants, by coincidence formant frequencies and the frequencies of the poles of the spectral density of the zeros of the characteristic frequencies of sounds, find some simple sounds and represent their codes (non sound, i.e. a cell address memory in which is stored a view of his character). This processing is performed by the processor. Simultaneously detect the change of sounds and pauses between words, phrases, which are pulses.

The selection of sound combinations with the characters. In monasterii their characters display are not only individual sounds simple, but double sounds-diphthongs and are generally often used in speech combinations of sounds, combining sequence, for example, 4 and even 5 separate sounds. Their detection is an important and difficult feasible, as the sounds of speech are performed sequentially. This complicates the handling of found sounds simple. The allocation of such sound combinations is carried out using a numeric register. The number of bits of the register select respectively the maximum number zvukoinzhenery General character. Code find simple sounds served on the code input register, and the input entry and shift as clock pulses serves pulses change sounds. E is the sequence will take the whole case and the first sound will be located in the last cell. By its code select all sequences of sounds, including the sound first. Sort the selected sequence, comparing their codes of the second sound ID sound in the penultimate cell of the register and so on, ending with a comparison of the codes of the first cell of the register codes and latest sounds, combinations, determine the detected combination of sounds and code them sounds simple select character code that is common to identify the groups of sounds. If you do not find the combinations of sounds, with a wildcard, then make up the character codes of simple sounds.

Construction of words and phrases perform serial output fontaniruyuschih characters detected in the speech signal common sounds and their combinations. At their request codes memory cells, which store the kinds of characters. Construction of words and phrases comply with accounting rules. While accounting rules are in the form of the amended provisions of printing characters upon detection of individual sounds is detected, the drums sound.

Control sounds do with the discovery of vowels "O" and "U", "And" and "S" is detected, percussion sound encoded rule. Control of these vowel sounds are provided by the decryption codes found in the river is x with some value "T". The amount of time "T" is found experimentally with the analysis of the duration of speech signals, for example, to a value equal to 1/2 the length of the percussive sound. In Fig. 3 shows the measured duration of speech sounds. The duration of the shock sound when the change was 0.3 and the value of "T" can be equal to 0.15 with.

The input and storage of characters. The characters of simple sounds and their combination are used in the form in which they are used fontanarrosa voice messages with manual recording sounds. The appearance of the symbols of monasterii presented in table 1. At the initial stage, during training equipment, type of graphic symbols is introduced into the storage device long-term storage of the sequence of coordinate points X1, Y1, X2, Y2, X3, Y3... using the input device of the computer, for example, used for the fast Fourier transform. The character first portrayed on translucent film mask attached to the display screen of the computer input device reproduce the kinds of characters moving beam on the display screen, locking in a storage device of the above coordinate points for each simple sound and their combinations, the cell address of the storage device when it is found on the according to certain rules to read the transcript. This selection vowels O, U; And, S; selection of percussion sound, lowering the letter in the word sounds coming from the drums. These rules involve displacing when it is written. Rules are entered in the storage device on the same initial stage, when you enter characters. These rules can be amended.

Entry perform is already built in characters of the image transcripts predominantly one "pen" Registrar, and the second "pen", for example, a different color is applied the main line (the second) patriachate staves scale which displays the text of phonetenormin on the storage media, for example, synchronously with spoken speech.

Explain the implementation of the method on a concrete example. Let speech pronounce the WORD. In a storage device for storing pre-recorded characters sounds and rules. The microphone sounds are formed in the speech signal. As shown in Fig. 2, the spectra of sounds sufficiently different from the detected formant F1, F2, F3 or pole of the spectral density in the form of a peak at a certain sound frequency, let this frequency f1. Two additional frequencies f2 and f3 aracterized the slopes of the peak and also characterize the sound. For we find three frequencies, which determine for each sound, pre-defined sounds and giving them the code they are symbols of simple sounds. Let Fig. 4 depicts these characters. The combination of "SL" has its own symbol, so we do not use the symbols of the sounds "s" and "L", and the requested memory combining these sounds their General character as the discovery of this combination. The main "O" of shock. The emphasis found in the control sounds by measuring the intervals of sounds and comparing them with a constant value T = 1/2 T max, where Tmax- the duration of the shock sound. The main sound "O" recognized by the decryption code. According to the rule, Turn the image drum sound is reflected on the letter of the rise of his character. For this discovery, percussion sound is encoded address of the requested rule, which appears in the form of the amendment provisions of the symbol when it is recording. Correction rate Y is two musical tone that is offset at an interval equal to the distance between lines of notes. Sounds that are after the drums sound in the word to the end are shifted down - Y, as shown in Fig. 4. Unstressed sound at the end of words according to the rules of shorthand is released. At about the comparison of Fig. 4 (right) shows the word "GLORY", in both cases the image is the same, and differ only by offset from the main line in accordance with the rules.

Detection of simple tones - known sign. It is made on the basis of short-time fast Fourier transform. Spectra of each simple sound are in the period of training apparatus using the same transducer Fourier, which will be used the way (or this information can be taken from literature). Then the mapping of the frequency characteristic of the sound spectrum of the speech signal, identify these sounds. When you process information about the form of symbols, rules, and characteristic frequencies of sounds can be entered using floppy disks.

Introduction the selection of sound combinations, the input and storage character, input and storage rules, the control of the sounds and the construction of words and phrases according to the rules vonostingroup.com writing and her characters enables automatic recording of speech in the form of phonetenormin.
