In addition shown in Fig. 5 c, even when carrying out specific talker's puncturing pattern, can not delete original talker's name, but it is showed, so the user can feel to seem oneself to be exactly this actual performer.Therefore, can express sensation and mood in a kind of natural mode, thereby can improve the efficient of foreign language studying.
By repeating this participation in learning, can learn this locality pronunciation of foreign language, thereby realize the high-level efficiency of study.In addition,, can delete specific talker's sound and caption data in an identical manner, and therefore can strengthen the study of foreign language according to user's selection.
In the above, illustrated by way of example various learning datas are stored in the digital memeory device of digital audio-frequency player, thereby and can read stored content selectively and realize speech study.Yet, also can from PC or from data server, download the data of various preparations, so that with its storage and will read selectively to realize foreign language learning.
Example 4
In this example, when foreign language studying, adopt the output channels of caption data to select and DAB.Referring to Fig. 6 and 7, at first, the operation of several roads of relevant conventional stereo or multichannel reproducer is described briefly.Describe with reference to this then the present invention is described.
The multichannel reproducer (Fig. 7) relevant with method of the present invention comprising: external data storage storer 110; External interface 190 is used to transmit data to external device (ED) and receives data from external device (ED); The user imports keypad 180; The control section 120 of the program that is used to drive total system has been installed therein; Demoder 130 is used for the converted digital audio signal; DAC140, the simulating signal that is used for switch decoders 130 conversions is so that output to loudspeaker to them by a plurality of at least sound channels; With screen driving arrangement 160, be used to drive a picture display device 170, this picture display device 170 shows caption data.
Can constitute interface 190 by different way, so that it can be by such as printer port (parallel port), serial port, USB (USB (universal serial bus)), live wire (IEEE1394) or the like and so on wired or launch data by the wireless route such as bluetooth.
The digital audio and video signals by demoder 130 conversions is a digital signal, therefore, by DAC140 they is converted to simulated audio signal again.Output signal is output to the loudspeaker 150 and 152 of corresponding sound channel, thereby realizes sound mixing effect.
Fig. 6 shows two loudspeakers, but its quantity can increase according to the quantity of the sound channel of distributing to demoder 130 or reduce.Fig. 7 has illustrated a plurality of loudspeakers based on the multichannel method.In addition, the present invention can be applied to resemble in the situation of using headphone or earphone in the classic method.Everything all should be within the scope of the present invention.
The size of considering picture display device 170 is determined the size of caption data piece, and corresponding caption data piece is synchronous with audio frequency output.That is to say that sound signal has the information about the starting position of each caption data piece.
By utilizing positional information above-mentioned, control section 120 synchronously outputs to picture display device 170 to caption data and sound signal.That is to say the positional information that control section 120 monitors in the sound signal that is being reproduced.Then, control section 120 compares the positional information of the positional information of sound signal and caption data.Then, instantaneous what occur synchronously, caption data is presented on the picture display device 170.
Utilize aforesaid device, learning method according to the present invention comprises the steps: to be checked the operator scheme of the reproduction of Set For Current by control section 120 after reappearing the operation signal of sound signal by keypad 180 inputs; By control section 120 (if operator scheme standard) control demoder 130, so that audio signal output is arrived corresponding right and L channel (R and L); If operator scheme has been set to R channel R, then control section 120 reappears sound signal by control demoder 130 and outputs to R channel R; If operator scheme has been set to L channel L, then control section 120 reappears sound signal by control demoder 130 and outputs to L channel L.
For convenience, suppose that digital audio file is a stereo file, in this stereo file, provide two sound channels as shown in Figure 6., in the multichannel recording method, provide more sound channel, in this mode, can be at these controls respectively of each sound channel.In stereo channels, standard, a left side and R channel only are provided, and in the multichannel method, have increased number of channels.
The user comes to select a kind of pattern by the relevant function key of the dish 180 that pushes button among mode standard, L channel output mode and R channel output mode.After selection function key, user select to talk learning data or Kara OK songs are so that be input to selected content in the control section 120 by the reproduction button of the dish 180 that pushes button.When reappearing beginning, synchronously caption data is presented on the picture display device 170 with sound signal.
Before being converted to reproduction mode, control section 120 is the state that is provided with of checked operation pattern at first.It is stored in the internal storage (RAM and ROM) of control section 120, and where necessary it is taken out use.As the result of checked operation pattern, if find it is mode standard, control section 120 is exported to demoder 130 to control signal so, to reappear relevant audio file, so that by a left side and R channel audio signal output is arrived loudspeaker 150 and 152.Therefore, two loudspeakers 150 and 152 after receiving this sound signal by a left side and R channel simultaneously with its output.Meanwhile, being presented at picture display device 170 with the synchronous caption data of sound signal, therefore, the user can watch caption data to learn speech by listening to audio output simultaneously.
Simultaneously, be L channel pattern or R channel pattern if find operator scheme, 120 of control sections are to demoder 130 output control signals, so that only export the signal of relevant sound channel.130 signal decodings of demoder to relevant sound channel, and the digital audio and video signals of output is converted to simulating signal by DAC140, so that finally by loudspeaker 150 and one of 152 outputs.
According to an example this output is described.
Under the situation of language learning, supposing has two talker A and B, and the talk between them is stored into respectively in a left side and the R channel.If the user wants to come the language speech by the talk of remembeing talker A, and want talk, then connect that sound channel, and turn off the sound channel of talker A with talker B speech with talker B.That is to say, come the setting operation pattern by this way.
After setting operation pattern in this way,, then make the sound channel of talker A quiet all the time if the user starts this reproducer.Therefore, the user can come implementation language study after remembeing literal or by the caption data of watching demonstration.Therefore caption data, shows caption data with standard mode without undergoing any preference pattern.Yet caption data also can be attached to selection mode, so that selectively with its output.
In addition, can start a kind of selected sound channel and non-other selected sound channel simultaneously.Reason is as follows: if connect single sound channel so that only by selected channel output signal, then do not start the remainder of sound channel, and only start a loudspeaker.That is to say, only export this sound signal, and this may provide real sensation by single loudspeaker., if the user causes fatigue only by a loudspeaker or only listen to by an earphone thereby then lose sense of hearing balance.
Therefore, after selecting a sound channel, if the user selects full sound channel reproduction mode, in other words, if selected sound channel is R channel R, if and selected full sound channel reproduction mode, 120 of control sections would be to control DAC142 by a kind of like this modes of signal of first and second loudspeakers 150 and 152 output R channel R.In this manner, when using headphone or loudspeaker, can keep sense of hearing balance.The method is shown in Figure 8.
Fig. 9 has illustrated the learning method of the present invention of wherein using multichannel.That is to say, expand stereosonic method,, and can export selected sound channel signal by all loudspeakers so that can select to corresponding sound channel.
