According to the present invention, if the determination result of the intonation for the utterance word is acceptable, it is printed, and if it is unacceptable, the printing is not performed. Can be recognized.

  An embodiment of the present invention will be described with reference to FIGS. In this embodiment, a portable printer that is portable as a voice memo printer is applied.

  Here, FIG. 1 is an external perspective view showing the voice memo printer 1 according to an embodiment of the present invention from the label discharge side, FIG. 2 is an external perspective view showing the voice memo printer 1 from the operator mounting side, and FIG. FIG. 2 is a horizontal sectional view showing the internal structure of the printer 1.

  As shown in FIGS. 1 to 3, a printer main body 1a of a voice memo printer 1 which is a portable portable printer includes a case 2 with one side opened, and a cover 3 for opening and closing the opened side of the case 2. It is comprised by. The cover 3 is rotatably supported by a fulcrum shaft 4 provided on the case 2. The case 2 is formed with a hopper 6 for storing the long recording paper 5 wound in a roll shape with the cover 3 closed. In the present embodiment, the recording paper 5 is one in which a large number of labels 5b are affixed to the mount 5a at equal intervals, but other recording paper may be used. The label 5b is coated with a glue having a weak adhesive force, and can be used as a sticky note P (see FIG. 8) after the printing is issued.

  In such a case 2, a paper guide 7 extending from the bottom of the hopper 6 toward the cover 3 is provided. A portion of the paper guide 7 near the cover 3 has a rotatable platen 8 and A label peeling body 9 along the longitudinal direction of the platen 8 is disposed.

  As shown in FIG. 3, a head support 11 having a thermal head 12 is provided on the inner surface of the cover 3 (on the hopper 6 side) so as to be rotatable around a support shaft 11a. The head support 11 is biased in one direction by a leaf spring 13, and the thermal head 12 comes into contact with the platen 8 with the cover 3 closed. That is, the printing unit 14 is formed by the platen 8 and the thermal head 12.

  Further, on both sides of the free end side of the cover 3, pinch rollers 16 that are pressed against the platen 8 by the urging force of the spring 15 are rotatably provided. Further, the cover 3 is formed with a label discharge port 17 that is disposed between the thermal head 12 and the pinch roller 16 and discharges the label 5b, and a paper presser 18 that presses the floating of the recording paper 5 in the hopper 6. ing. The case 2 is formed with a mount discharge port 19 for discharging the mount 5 a between the free end of the cover 3.

  On the upper surface of the case 2, a power switch 20 that declares ON / OFF of power supply from the battery 10 (see FIG. 3), a feed switch 21 that performs printing on the label 5 b, a lid 22, and a light receiving window that receives infrared rays. 23 is provided. The lid portion 22 opens and closes when the battery 10 is attached to and detached from the battery storage portion 30 (see FIG. 3) provided to be opened on the upper surface that is one surface of the case 2. Further, locking claws 24 are slidably provided on both sides of the cover 3 (see FIG. 1). These locking claws 24 are urged outward to be locked to the case 2, and when the cover 3 is opened, the locking claws 24 are slid inward as indicated by the arrow marks to engage with the case 2. Release the stop state.

  A built-in microphone 52 is provided on the same surface of the case 2 as the label discharge port 17. The voice memo printer 1 according to the present embodiment is equipped with a voice recognition function, and the built-in microphone 52 is used when executing the voice recognition function.

  In addition, an LED 56 is disposed on the upper surface of the case 2. The voice memo printer 1 of the present embodiment can notify the operator of the operation state of the voice memo printer 1 by turning on or blinking the LED 56.

  Further, as shown in FIG. 2, an arc surface 25 is formed on one surface of the printer body 1a opposite to the cover 3 so as to be in close contact with the operator's waist. On the other hand, a non-slip 26 for reducing slippage and a belt hook 27 which is hooked on the operator's belt so as to face the non-slip 26 are formed.

  With such a configuration, when the battery 10 is correctly stored in the battery storage unit 30, the terminal of the battery storage unit 30 and the terminal of the battery 10 come into contact with each other while the power switch 20 is ON. Thus, power is supplied from the battery 10 to each part such as the thermal head 12 that requires power supply.

  In such a voice memo printer 1, when the recording paper 5 is set, the cover 3 is opened, the recording paper 5 wound in a roll shape is stored in the hopper 6 of the printer main body 1a, and the cover 3 is opened. In this state, the front end of the recording paper 5 is pulled out to a position covering the platen 8 and the label peeling body 9 to close the cover 3. As a result, as shown in FIG. 3, the leading end portion of the mount 5a of the recording paper 5 is pressed against the platen 8 by the thermal head 12 and the pinch roller 16, and the pull-out path of the mount 5a is formed by the label peeling member 9. The recording paper 5 is bent at an acute angle and the recording paper 5 is prevented from floating from the bottom surface of the hopper 6. The printer main body 1a on which the recording paper 5 is set can be used by placing it on a desk, but it can also be used even when it is usually worn on the operator's waist.

  Next, the connection of the control system of each part of the voice memo printer 1 will be described with reference to FIG. The voice memo printer 1 includes a CPU (Central Processing Unit) 41 that centrally controls each unit. The CPU 41 stores a ROM (Read Only Memory) in which fixed data such as a program executed by the CPU 41 is written. 42, a RAM (Random Access Memory) 43 in which variable data such as work data is renewably written, and a flash memory 44 for registering various information are connected via a bus line 45. Then, a thermal head driver 46 for driving the thermal head 12, a motor driver 48 for driving a motor 47 connected to the platen 8, a sensor circuit 50 to which various sensors 49 are connected, and a cover open that is turned on and off by opening and closing the cover 3. A switch circuit 54 to which the switch 51, the power switch 20 and the feed switch 21 are connected, an infrared interface 55, and a lighting control circuit 57 to which the LED 56 is connected are connected to the CPU 41. As described above, the circuit shown in FIG. 4 is formed on a substrate (not shown) provided inside the printer main body 1a. The infrared interface 55 is disposed inside the light receiving window 23 described above. The interface is denoted as I / F in the figure.

  The CPU 41 is connected with a voice input CODEC 53. A built-in microphone 52 is connected to the audio input CODEC 53. The audio input CODEC 53 functions as an A / D conversion unit, converts audio analog data input from the built-in microphone 52 into audio digital data, and outputs the audio digital data to the CPU 41.

  Further, a speech recognition engine 58 is connected to the CPU 41. The voice recognition engine 58 analyzes voice digital data input from the built-in microphone 52 and generated by the voice input CODEC 53, and converts human voice into text. Such a speech recognition engine 58 includes, for example, an acoustic dictionary 59 in which acoustic features (phonemes) of small units (phonemes) of human speech are registered, and a language pattern dictionary 60 in which language features of words to be recognized are registered. Voice recognition is performed using.

  The words to be recognized by speech registered in the language pattern dictionary 60 of the present embodiment are limited to specific applications. Since a specific word is often issued in a specific application, the language pattern dictionary 60 can be configured at low cost by registering only the words focused on the specific application in the language pattern dictionary 60 in this way. . Specifically, conversations and utterances that are likely to be used in the intended use are collected in a list and used as a use language table (not shown). For each language registered in this use language table for each application, the frequency of the language is analyzed and separated into speech features (phoneme information) and language features (phoneme series information). The language features separated in this way are registered in the language pattern dictionary 60.

The acoustic dictionary 59 is used as a dictionary related to voice recognition in general, not by use. The principle of speaking is
(1) “My throat trembles”
(2) “Passing through oral cavity / nasal cavity”
Therefore, the acoustic dictionary 59 stores information for specifying the shapes (1) and (2) from the voice frequency.

  As shown in FIG. 5, the speech recognition engine 58 having such a configuration performs frequency conversion on speech digital data input from the built-in microphone 52 and generated by the speech input CODEC 53 by a frequency analysis unit 58a which is a frequency analysis means. And the acoustic feature is calculated based on the acoustic dictionary 59 in the comparison unit 58b which is speech recognition means (speech feature extraction means). At this stage, only the shapes (1) and (2) described above can be identified, and any of the 50 sounds cannot be identified yet. Therefore, from the words registered in the language pattern dictionary 60, a word whose language feature is closest to the acoustic feature of the input speech is searched for and output as a speech recognition result (language feature extraction means). By comparing with the language pattern dictionary 60 in this way, “Aiueo” or the like can be specified for the first time. It is difficult to specify when a large number of unspecified words are uttered, but if you try to narrow down to words that are uttered for a specific purpose and compare the relationship of (1) and (2) above and the characteristics of the phoneme sequence waveform, The possibility of misrecognition can be suppressed as much as possible, and speech recognition is possible with such a simple mechanism.

  The language pattern dictionary 60 can be updated from an external device by connecting an external device (such as a personal computer) (not shown) to the voice memo printer 1 via the infrared interface 55. Further, the contents of the language pattern dictionary 60 are changed by exchanging the language pattern storage chip (dictionary) for storing the language pattern dictionary 60 or rewriting the registered contents by downloading the language pattern dictionary 60 from an external device (such as a personal computer) (not shown). It is also possible to change for each specific application. When a new language pattern dictionary 60 is downloaded via the infrared interface 55, the old language pattern dictionary 60 is deleted.

  In addition, the speech recognition engine 58 of the present embodiment can confirm whether or not the words are uttered with the correct intonation in addition to the speech recognition as the words as described above. Specifically, as shown in FIG. 5, the speech recognition engine 58 includes a speech pitch extraction unit 58 c which is speech pitch extraction means from speech digital data input from the built-in microphone 52 and generated by the speech input CODEC 53. Whether or not the voice is extracted with the correct intonation in the score determination unit 58d as the determination means based on the voice pitch extracted by the voice pitch extraction unit 58c, the voice recognition result in the comparison unit 58b described above, and the pitch dictionary 61. Determine whether.

  The pitch dictionary 61 stores “time-sequential pitch data (pitch sequence)”, which is voice pitch and intonation data, in pairs with “spoken words”. Specifically, the voice pitch is extracted from the voice digital data, and the periodicity is analyzed by the linear prediction method or the maximum entropy method, etc., to generate “time series pitch data (pitch series)” and register it with the spoken word It is a thing. For example, when an English teacher uses the voice memo printer 1 for speech practice, the teacher utters a word and registers “spoken words” and “time-series pitch data (pitch series)” in the pitch dictionary 61. I will leave. That is, for example, “spoken words” having different meanings, such as “rain” and “称”, whose name is “Ame”, are distinguished and registered in the pitch dictionary 61.

  The pitch dictionary 61 can be updated from an external device by connecting an external device (such as a personal computer) (not shown) to the voice memo printer 1 via the infrared interface 55. Further, the contents of the pitch dictionary 61 can be changed by exchanging the pitch dictionary storing chip (dictionary) for storing the pitch dictionary 61 or rewriting the registered contents by downloading the pitch dictionary 61 from an external device (such as a personal computer) (not shown). Is possible. When a new pitch dictionary 61 is downloaded via the infrared interface 55, the pitch dictionary 61 is deleted.

  Therefore, such a pitch dictionary 61 can select a dictionary in which the same words are different in intonation and utterance words at the place of use. For example, a pitch dictionary of “Osaka dial” is used for a lunch box in the Kansai region, and a pitch dictionary of “Tokyo dialect” is used for a lunch box store in the Kanto region. Of course, it is also possible to switch to the use of a “standard language” pitch dictionary.

Here, the determination method in the score determination part 58d is demonstrated based on the example shown in FIG. The cross-correlation method is used to determine whether the pitch sequence is similar to the time axis. This cross-correlation method is a method generally used to determine the similarity of two functions. According to the example shown in FIG.
Σ Teacher utterance × Teacher utterance = 207584.6283
Σ Teacher utterance x User utterance 1 = 225362.7706
Σ Teacher utterance x User utterance 2 = 229427.6884
Therefore, the standard deviation degree of each user utterance is
User utterance 1 = (Σ teacher utterance × user utterance 1) / (Σ teacher utterance × teacher utterance) * 100
= 92.11%
User utterance 2 = (Σ teacher utterance × user utterance 2) / (Σ teacher utterance × teacher utterance) * 100
= 90.48%
Is calculated as For example, when 91% or more is assumed to be uttered with correct intonation, user utterance 1 is determined to be uttered with correct intonation because user utterance 1 is 91% or more, and user utterance 2 is 91% or less. It is not determined that the voice was uttered with the correct intonation. The score determination unit 58d outputs a speech recognition result for the speech determined to be uttered with correct intonation in this way.

  Next, of the functions that the control program stored in the ROM 42 built in the voice memo printer 1 causes the CPU 41 to execute, the characteristic functions provided in the voice memo printer 1 of the present embodiment will be described.

  Here, the voice printing process executed by the CPU 41 of the voice memo printer 1 will be described. FIG. 7 is a flowchart showing the flow of the voice printing process. As shown in FIG. 7, when a digitized voice is input (Y in step S1), the process proceeds to step S2, and it is determined whether the process is a recognition pattern registration process or an utterance voice recognition process.

  If it is determined that the speech recognition processing is utterance, the speech recognition processing by the speech recognition engine 58 is executed (step S3).

  If it is determined in the speech recognition process that the word is registered in the language pattern dictionary 60 (Y in step S4), the word whose language feature is closest to the acoustic feature of the input speech is searched and printed as a speech recognition result. The data is output to the section 14 and printed (step S5: printing means).

  If it is determined in the voice recognition process that the word is not registered in the language pattern dictionary 60 (N in step S4), the process returns to step S1 without performing voice recognition.

  On the other hand, if it is determined that the process is a recognition pattern registration process, the process advances to step S6 to execute a recognition pattern registration process. In the recognition pattern registration process, conversations and utterances that will be used in the intended use are collected in a list and used as a use language table (not shown) for each use, and each language registered in this use language table for each use Each time, the frequency of the language is analyzed and separated into speech features (phoneme information) and language features (phoneme sequence information). Then, the language features separated in this way are registered in the language pattern dictionary 60.

  Such a voice memo printer 1 can be used in any scene. For example, in an English pronunciation test, if the determination result in the score determination unit 58d is acceptable, printing is performed, and if it is unacceptable, printing is not performed, so that the speaker is recognized as unacceptable. May be. Here, FIG. 8 is a plan view showing an example of the issued sticky note P. FIG. As shown in FIG. 8, the text “Apple” in the case where “Apple” is correctly spoken is printed on the sticky note P. Only determination results (pass / fail, score, deviation degree, etc.) may be printed.

  Thus, according to the present embodiment, if the intonation or pronunciation determination result for the utterance wording is acceptable, it is printed, and if it is unacceptable, the printing is not performed. It is possible to recognize whether or not pronunciation is possible. In addition, by printing intonation and pronunciation determination results (pass / fail, score, deviation degree, etc.) about the utterance wording, it is possible to make the speaker recognize the intonation and utterance of the utterance wording.

  In addition, when using the pitch dictionary 61 for a lunch box in the Kansai region, the pitch dictionary for “Osaka dialect” is used for a lunch box in the Kansai region, and for the lunch box store in the Kanto region, the pitch dictionary “Tokyo dialect” is used to receive an order at a bento store. In addition, since the ordered product is issued on the sticky note P simply by speaking about the ordered product, the issued sticky note P can be used as an order form. If the order slip is affixed to the product when the product is delivered, it is possible to prevent the product from being mixed.

  In addition, according to the present embodiment, the utterance wording includes the voice pitch extracted by the voice pitch extraction unit 58c, the voice recognition result output by the comparison unit 58b, and the utterance word stored in the pitch dictionary 61. And the time-series pitch data. This makes it possible to distinguish and print words having different meanings even with the same name, such as “rain” and “飴” whose utterance is “Ame”.

  In the present embodiment, the single language pattern dictionary 60 that registers the linguistic features of words for specific applications to be recognized by speech is provided. However, the present invention is not limited to this. A plurality of language pattern dictionaries 60 each registering the language characteristics of the word may be provided. In this case, the language pattern dictionary 60 may be switched and used for each specific application. The language pattern dictionary 60 may be switched according to the input voice content or may be switched by a switch.
