The host computer 1 is connected to a print data generation apparatus 10 mounted on the image forming apparatus 3 via a parallel cable, a serial cable, a USB cable, a network connection, a wireless LAN line, the Internet, and the like. On the other hand, the portable terminal 2 is connected to a print data generation apparatus 10 mounted on the image forming apparatus 3 via a network line, the Internet, or the like.

  Then, the user digitally records voice information desired to be printed as text or image data using the digital recording function of the host computer 1 or the portable terminal 2, and generates (or saves) the digital voice data as a file. A print request for the data file is transmitted to the print data generation device 10 of the image forming apparatus 3 in the same manner as during normal printing. There are various digital audio data format formats, and there is a PCM (Pulse Code Modulation) format as a general format format. This format is audio data digitized by sampling and quantization for analog audio represented by a continuous waveform.

  As shown in FIG. 2, a printing data generation apparatus 10 as an example of an embodiment of the present invention includes a digital audio data receiving unit 11, a data format determination unit 12, a digital audio data analysis unit 13, and a digital audio data conversion unit. 14 is provided.

As specific speech analysis processing, for example, a part that can be recognized as a human voice is identified from digital speech data by a technique such as pattern matching, and one-element data is extracted with a silence state data part as a delimiter. Next, as the detailed analysis, the extracted one element data is further decomposed to the phoneme level, and the decomposed one phoneme is replaced with an internal code based on the internal code information mounted in the analysis technique mounting unit 20.
Then, digital audio data extracted as one element data and further decomposed into one phoneme is generated as intermediate data in a list format (list number, data part list) (see FIG. 3).

  The intermediate data format generated here can be expressed not only in the list format but also in the XML format. Further, the format to be basically analyzed is the PCM format, but in this embodiment, the audio data in the other format is dealt with by the digital audio data analyzing means 13 converting it into the PCM format. An example is MP3 → PCM format conversion. This format conversion method is also mounted in the analysis method mounting unit 20.

The digital audio data conversion means 14 has a conversion method mounting unit 21 in which a digital audio data conversion method according to the correspondence table 17 is mounted. Characters that can be printed by the image forming apparatus 3 for each element expressed in a list format (or XML format) using the intermediate data as a data source using the digital audio data conversion method determined by the data format determination unit 12 Or image code data (see FIGS. 4 and 5). At this time, if it is found that the code data includes Japanese (for example, hiragana or katakana), kanji conversion or the like is performed based on the dictionary information installed in the conversion technique mounting unit 21.
In this way, print data is generated, and the print data is sent to the print output processing unit 22 of the image forming apparatus 3 to perform a predetermined print process.

In step S2, the digital audio data analysis method and the digital audio data conversion method corresponding to the data format of the digital audio data are determined with reference to the correspondence table 17, and the process proceeds to step S3.

In step S3, the digital audio data is analyzed using the digital audio data analysis method determined in step S2, and intermediate data before being converted as characters or image information is generated based on the analysis processing result. The process proceeds to S4.
In step S4, using the digital audio data conversion method determined in step S2, the intermediate data is converted into data data that can be printed by the image forming apparatus 3 using the data source, and the process proceeds to step S5.

In step S5, it is determined whether or not there is Japanese in the code data converted in step S4. If it is determined that there is no Japanese, the process proceeds to step S7, and if it is determined that there is Japanese. Then, after proceeding to step S6 and performing kanji conversion, the process proceeds to step S7.
In step S7, the code data is transmitted as print data to the print output processing unit 22 of the image forming apparatus 3, whereby a predetermined print process is started.
