Fig. 6: the detailed maps of keyboard matrix of the present invention;
Fig. 7: the floor map of phonetical repeater of the present invention.
Phonetical repeater of the present invention as shown in Figure 1, it can link with a video equipment (not shown) that includes a videocassette recorder.It also connects (being shown in greater detail among Fig. 6) with the keyboard with various function keys, so that the general utility functions of effective language exercise function and phonetical repeater.
As shown in Figures 3 and 4, phonetical repeater of the present invention is made up of following part, and one and microcomputer 3 joining phonetic synthesis storeies 2 store the program of setting earlier of giving in the microcomputer 3.Based on this structure, phonetical repeater of the present invention has the function that can make the sound that is recorded on audiotape or the video-tape repeat playback automatically.What be connected to microcomputer 3 has keyboard 1 and a display unit DISPLAY, and this unit comprises LCD (LCD) driving circuit and LCD; Phonetic synthesis storer 2 is made up of random access memory (RAMS) RAM1～RAM4 and a voice operation demonstrator circuit SYSCOON.A magnetic tape cassette mechanism 5 connects with microcomputer 3.The output of magnetic tape cassette mechanism 5 is delivered to audio level sensor 4 through recording playback amplifier 7, can realize automatic pronunciation training function like this and repeat player function automatically.
Critical function of the present invention comprises two tape transport functions, full-automatic reverse function, by the continuous player function of a magnetic tape mechanism to another mechanism, synchronization function, editting function, pronunciation training function, the statement memory function repeats player function automatically, the tape speed control function, function, distant control function and the double speed sound-recording function of automatic video replay band sound.
At first, just repeat player function automatically, can adopt two kinds of methods to realize that a kind of method is rewinding after playback, another kind of method is that repeat playing is stored in the voice signal in the phonetic synthesis storer 2; In one method of back, automatically the number of times that repeats playback is by the numerical key of pressing statement storage key SM and desired times (0～9) decision, and SM is one of function key of keyboard 1, presses auto key AR then, identify on the tape and do not write down partly, by one section sound of number of times repeat playing of setting.When audio level sensor 4 recognizes on the tape record partly the time, receive a low level signal at its input end, at this moment be connected the triode TR1 remain off state of the output terminal of audio level sensor 4, correspondingly acoustical signal exports main amplifier 8 to through microcomputer 3.
Equally, after pressing the SM key, press repeated storage key RM again, can make all statements that are set to the last one all repeat to let slip.In this case owing to omitted the rewinding process, so can prolong machine serviceable life.Press auto key AR or playback button then, make it stop the statement of repetition playback and continuation broadcast setting repeat statement back.Repeat the playback number of times and set as required, select a numerical key, afterwards, press repeated storage key RM again, institute's attribute sentence is play by selected repetition of figures.
Secondly, about interactive function, one connects a ground playback utilization and presses language fit key LP-2 and carry out, and the interactive function meaning is meant, when making when answering playing statement by microphone amplifier MICAMP, continues to play next statement; This interactive function can have two kinds of methods to realize that a kind of method is finished by following steps, and when audio level sensor 4 recognized the not record part of tape, it was out of service to control tape immediately in the statement playing process; When audio level sensor 4 detects the recall signal that receives through microphone amplifier MICAMP,, play next statement to continue according to the instruction continuation operation tape of microcomputer 3.The step of another method is: in the statement playing process, audio level sensor 4 detects when not writing down partly in the tape, stop the tape operation, even when audio frequency is flated pass sensor 4 when not detecting recall signal through microphone amplifier MICAMP, through behind the time interval a corresponding to next statement, instruction according to microcomputer 3 continues the operation tape again, plays next statement.
The 3rd, about the synchronous recording function, it is that the language fit key LP-1 that presses on the keyboard 1 finishes, press function key LP-1, recorded from the sound of tape transport A on the R channel of tape transport B tape, the acoustical signal of microphone amplifier MICAMP reception is simultaneously recorded on the L channel of B tape, and this just reaches the purpose of synchronization.
The 4th, about looking the automatic repeat function of acoustical signal, it is the function of audiovisual formula language exercise device, when audio-visual speech exercise is connected video-unit and realized by this phonetical repeater, can only listen to repeatedly as required and look/one section sound of sound system.At repeated storage key RM and the auto key AR state that all is pressed, video image stops on the screen, at this moment is stored in looking acoustical signal and can not repeat automatically under the ruuning situation at tape in the phonetic synthesis memory 2.When observation one is in static or puts the picture of state slowly, can listen to repeatedly and the corresponding sound of picture by needed playing speed, can strengthen the audio-visual instruction effect.
The 5th, about single-tone pronunciation exercises function, this is to play to be contained in the process of the tape A ' among the tape transport A, with A ' with on acoustical signal transcribe the R channel of the tape B ' that is contained among the tape transport B, the acoustical signal of the microphone that will be received by microphone amplifier MICAMP is recorded on the L channel of tape B ' simultaneously.Its process is, presses under the record button situation on the lower keyboard 1, recorded an interval by the sound of tape A ' broadcast, then, begins to record the sound of microphone.So just finished the single-tone pronunciation exercises.
In addition, the phonetical repeater of the present invention speed controlling function that also has stereo copy function and change playing speed from tape A ' to tape B '.
Can find out significantly by above-mentioned, the invention provides a kind of phonetical repeater with catalog feature, it can remove in rerecording does not need partly, but compartment of terrain record acoustical signal in repeating playback, and can accurately finish sound-recording function at interval, this phonetical repeater also has the effect in the serviceable life that can prolong magnetic head and tape, owing to when seeing the static or picture that proceeds slowly, listen to corresponding sound repeatedly, so can strengthen the effects on hearing in the audio-visual instruction; Because repeating to use the phonetic synthesis storage unit under the playback situation, therefore, magnetic head is not in and the contacted state of tape.This phonetical repeater has sound-recording function and the distant control function that can edit.In addition, this phonetical repeater is owing to use an audio level sensor (speech transducer) so pronunciation exercises, repeat to watch and listen to and can both carry out automatically.So this phonetical repeater just has can be to original transcription and the actual language exercise function that pronounces to compare analysis.
Though the present invention discloses preferred embodiment in narration, those of ordinary skill in the art can be interpreted as; May make various improvement, replenish and replace, this does not exceed claim of the present invention scope of disclosure.
