a converting unit converting the first word by a first conversion method, and converting the second word by a second conversion method, the second conversion method being different from the first conversion method.

3. The information processing system of claim 1 , wherein

the analyzing unit carries out an analysis to determine whether voiceprint data of the voice data is voiceprint data of a registered user, and

the erasing unit erases a voice data of a person other than the registered user, based on the result of the analysis carried out by the analyzing unit.

4. The information processing system of claim 1 , wherein the erasing unit varies the period of time from the analysis carried out by the analyzing unit to the erasing, between a voice data of the registered user and a voice data of a person other than the registered user.

5. The information processing system of claim 1 , further comprising

a warning unit issuing a warning when the text data generating unit fails to generate text data from the voice data.

6. The information processing system of claim 1 , further comprising

a reproducing unit reproducing the voice data when the text data generating unit fails to generate text data from the voice data,

wherein the erasing unit erases the voice data reproduced by the reproducing unit, in accordance with the result of the analysis carried out by the analyzing unit.

7. The information processing system of claim 6 , wherein, after a predetermined period of time has passed after the reproduction, the erasing unit erases the voice data reproduced by the reproducing unit, in accordance with the result of the analysis carried out by the analyzing unit.

8. The information processing system of claim 1 , further comprising

a portable-terminal housing including the reproducing unit, the portable-terminal housing being portable.

9. The information processing system of claim 1 , wherein the voice data relates to a question, and

the text data generating unit generates the text data according to an answer to the question.

10. An information processing system comprising:

a memory that memorizes voice data from a portable terminal;

a generating unit that generates data in accordance with the voice data;

a communicator that transmits the data to the portable terminal; and

a controller that erases the voice data in the memory after a predetermined period has passed.

11. The information processing system of claim 10 , further comprises an analyzing unit that analyzes voiceprint data of the voice data, and

the controller erases the voice data in accordance with a result of the analysis by the analyzing unit.

12. The information processing system of claim 10 , wherein the generating unit generates data in accordance with a positional data of the portable terminal.

13. The information processing system of claim 12 , wherein the generating unit generates first data according to the voice data and second data according to an answer to the voice data.

14. The information processing system of claim 13 , wherein the communicator transmits the first data and the second data to the portable terminal by a wireless.

15. The information processing system of claim 14 , the controller erases the voice data converted into the data immediately.

16. The information processing system of claim 10 , wherein the controller erases the voice data converted into the data.

17. The information processing system of claim 10 , wherein the generating unit generates text data as the data.

18. A method of controlling a processing system comprising the steps of:

memorizing voice data from a portable terminal;

generating data based on the voice data;

transmitting the data to the portable terminal; and

erasing the voice data after a predetermined period has passed.

19. The method of controlling the processing system of claim 18 , further comprises analyzing voiceprint data of the voice data, and

wherein the step of erasing erases the voice data is based on a result of the analyzing.

20. The method of controlling the processing system of claim 18 , wherein the step of generating generates the data based on a positional data of the portable terminal.

21. The method of controlling the processing system of claim 20 , wherein the step of generating generates first text data based on the voice data and second text data based on an answer to the voice data.

22. The method of controlling the processing system of claim 21 , wherein the step of transmitting transmits the first text data and the second text data to the portable terminal by a wireless.

23. The method of controlling the processing system of claim 22 , wherein the step of erasing erases the voice data converted into the data immediately.

24. The method of controlling the processing system of claim 18 , wherein the step of erasing erases the voice data converted into the data.

25. The method of controlling the processing system of claim 18 , wherein the step of generating generates text data as the data.
