Definitions

  • the invention relates to an electronic text generator for the delivery of short texts, for example announcements, in the form of analog electrical signals, in which the short texts can be composed of text parts of different lengths of time stored in digital form in a read-only memory, with a control device to which the read-only memory is transmitted a memory address counter is connected and a digital-to-analog converter connected downstream of the read-only memory.
  • Such text providers are generally known. They are, for example, for voice output over the telephone network, for example in order processing in the trade or also. have been used for answering machines. They can be controlled from a data processing system, for example a microcomputer.
  • the conversion of the texts to be stored in the read-only memory into digital voice data can be carried out in accordance with the known method. delta modulation.
  • the digital-to-analog converter downstream of the read-only memory then contains one. Delta modulator.
  • a fundamental problem of the text generators of this type is that they still require a relatively large amount of memory in the read-only memory. As a result, the facilities become technically and costly complex, which is particularly noticeable when it comes to smaller facilities for the delivery of one or more short texts, as can occur, for example, in an answering machine.
  • the object on which the invention is based is to design a text generator of the type mentioned at the outset in such a way that short texts of various types and compositions can be given with a minimum of storage spaces.
  • the invention is based on the basic idea that no storage spaces are required for predetermined speech pauses between the text parts composing the short text and that identical text parts that occur in several texts should only be saved once.
  • a text-part decoding device for detecting a marking in the digital data associated with each text-part end is connected to the output of the read-only memory, which emits a text-part-end signal and outputs predetermined speech pauses between two text parts at the output
  • a speech pause decoding device is connected to the memory address counter for recognizing pause start or pause end markings which are emitted by the memory address counter, the data delivery of the read-only memory being interrupted between a pause start and a pause end mark, and the speech pause decoding device being a pause end Signal and the off the end of the text decoding device and the speech pause decoding device via an .or gate with the control device. are connected to advance the program flow.
  • the ends of all parts of the text that compose the entire text are therefore identified by inaudible markings in the digital data. These markings are expediently the same for all text parts and are not bound to a specific data storage address. This enables an individual definition of the text part lengths that corresponds exactly to the respective text part.
  • the markings are recognized by the end of text decoding device, which generates a corresponding end of text signal.
  • the language breaks are treated like parts of text when the program is created. However, they are not stored in the read-only memory, but an address range is specified for the duration of the pause in which the read-only memory is not populated.
  • the speech pauses can be generated by presetting certain pause start addresses in the memory city counter, which are recognized by the speech pause decoding device which is a pause and. End of break signal emits. The end of text signal and the end of pause signal are used to further control the program flow.
  • the speech pause decoding device Since no data is supplied to the digital-to-analog converter from the read-only memory during the pauses in speech, it is expedient if, according to claim 2, the speech pause decoding device emits a control signal during a predetermined speech pause, by which the input. of the digital Analog converter is connected to a device for emitting a fixed input signal, so that it receives the digital input data during the pauses in speech, which generate the NF level "0" at the converter output.
  • Another particularly advantageous embodiment of the text generator according to the invention is the subject of claim 5. It is expedient to monitor the low-frequency signal emitted by the digital-to-analog converter in order to immediately detect any faults which, for example, can lead to text mutilation. By coupling this monitoring of the output low-frequency signal with the speech pause decoding device, a particularly sensitive monitoring of the low frequency is possible, which then, since it does not respond to the specified speech pauses, can be designed so sensitive that it detects even the smallest interruptions in the low frequency Signal in the range of approx. 6a milliseconds reacts.
  • the program sequence is controlled by a control device which, depending on the purpose of the text generator, is sent to other monitoring and control devices, for example a microprocessor. can be connected. All parts of the text to be delivered, which can be announcements, for example, are digitized according to the known principle of delta modulation and stored in the read-only memory 3 (for example ROM, EPROM) one after the other.
  • the start addresses of these text parts stored in the read-only memory 3 are defined in a known manner in the control program and are given by the control device 1 to the memory address counter 2.
  • the ends of all parts of the text are marked by inaudible marks in the digital data. These marks are the same for all text parts and are not tied to a specific data storage address.
  • the text parts are output in such a way that the memory address counter 2 points to the fixed value memory start address of any text part. is preset and incremented from this counter reading, specifically controlled by a clock signal with the frequency f6 originating from the clock generator 12. In this way, the content of one memory cell after the other is released and fed to the digital-to-analog converter 5.
  • the read-only memory 3 is constructed in a known manner in byte-by-byte organization, ie 8 bits are given simultaneously to 8 outputs under each address. For this reason, a parallel-to-serial converter 4 must be switched on before the digital-to-analog converter 5, which can only process 1-bit serial information.
  • the marking which occurs at the end of a text part is recognized by the text part end decoding device 8 and, via an OR gate O, a corresponding text part end signal becomes the control direction 1 and the memory address counter 2 supplied.
  • Predefined speech pauses are generated between the individual text parts in such a way that, according to the program entered, the memory address counter 2 is set to an address within a previous address range in which the read-only memory 3 itself is not populated.
  • the procedure can be such that a certain fixed value in the memory address counter 2 is assigned to the end of the pause, which is the same for all speech pauses.
  • Pauses of different lengths can then be realized by programming different start addresses within this area. In this way, longer speech pauses can be achieved by lining up several pause sections.
  • the pause start and pause markings output by the memory address counter 2 or the pause end markings alone are recognized by the speech pause decoding device 9.
  • a speech pause end signal is generated, which is likewise supplied to the control device 1 and the memory address counter 2 via the OR gate O.
  • the digital-to-analog converter 5 which is constantly clocked by the clock generator 12 with a clock signal of the frequency f3, emits an analog output signal which runs through a playback filter 6 and is thereby limited to the frequency band relevant for voice announcements, which also applies to the Digitization inevitable quantization noise is dampened.
  • the low-frequency signal reaches the output NF-A via a downstream amplifier 7.
  • the pause decoder 9 emits a control signal during the pauses in speech, by means of which the input of the digital-to-analog converter 5 is connected to an output of the clock generator 12 during the speech pauses by means of a switch S, from which a clocked input signal of frequency f4 is supplied from the digital-to-analog converter 5.
  • This input signal expediently has the frequency. f4 - 1/2 x f3.
  • a program monitoring device 10 controls the program sequence and transmits the control signals to the memory address counter 2 via an AND gate U, to which the clock signal f6 is simultaneously fed. Program ends are indicated via the P-Ü output.
  • a device 11 for monitoring the low-frequency signal fed to the output NF-A indicates a fault in the delivery of this signal via the output NF-Ü.
  • the device 11 can be very sensitive be designed for failure of the low frequency signal monitoring device because it is only released when "text" is programmed, ie. during the predetermined speech pauses, it is switched off by a control signal emitted by the speech pause decoding device 9. In this way, monitoring of the low-frequency signal emitted is carried out very quickly.
