Abstract

A mobile telephone is composed of an antenna, a sending/receiving section, an automatic response control section, a memory, a key input section, a dial locking control section, a control section, a speech recognition section, a timer, a display section, a speech input section, a counter and a speaker. A character code from the key input section is stored in the memory. The control section determines if an aural signal is coincident with the character code stored in the memory. If there is coincidence, dial locking is set by the dial locking control section.

Claims

1. A mobile terminal provided with a speech recognition function, comprising:

registering means for registering a desired character code;

aural signal recognition means for recognizing an aural signal;

determination means for determining whether said character code registered by said registering means and said aural signal recognized by said aural signal recognition means are coincident or not; and

locking setting means for setting key locking when said determination means determines that said character code and aural signal are coincident.

5. A mobile terminal according to claims 1 or 2, including:

key locking release means for releasing a key locked state set by said key locking means when said determination means determines that said aural signal and said character code are coincident.

6. A mobile terminal according to claims 1 or 2, wherein:

said determination means determines plural times whether said aural signal and said character code are coincident or not.

7. A mobile terminal according to claim 1 or 2, wherein:

said mobile terminal is a mobile telephone.

8. A mobile terminal according to claim 7, wherein:

said key locking setting means is dial locking setting means.

2. A mobile terminal provided with a speech recognition function, comprising:

registering means for registering a desired character code;

response means for responding to an incoming call;

recognition means for recognizing an aural signal when said response means responds;

determination means for determining whether said character code registered by said registering means and said aural signal recognized by aural signal recognition means for coincident or not; and

locking setting means for setting key locking when said determination means determines that said aural signal and said character code are coincident.

3. A mobile terminal according to claim 2, including:

a button pressed to determine whether said response means is set or not.

4. A mobile terminal according to claim 2, wherein:

said response means sends a message showing that a response is made when responding to said incoming call; and

after said message is sent, said response means becomes a recording state for recording said aural signal.

9. A mobile terminal provided with a speech recognition function, comprising:

a memory for storing a desired character mode;

an aural signal recognition circuit for recognizing an aural signal;

a control section for detecting whether said character code stored in said memory and the recognized aural signal are coincident or not; and

a dial locking setting control section for setting key locking when coincidence between said character code and said aural signal is detected.

10. A mobile terminal provided with a speech recognition function, comprising:

a memory for storing a desired character code;

an automatic response control section for outputting an off-hook signal in response to an incoming call;

a recognition circuit for recognizing an aural signal when a response is made;

a control section for detecting whether said character code stored is said memory and the recognized said aural signal are coincident or not; and

a locking setting control section for setting key locking when coincidence between said aural signal and said character code is detected.

11. A mobile terminal according to claim 10, wherein:

it is determined by pressing a button whether said response control section is set or not.

12. A mobile terminal according to claim 10, wherein:

said response control section sends a message showing that a response is made when responding to said incoming call; and

said response control section becomes a recording state for recording said aural signal after said message is sent.

13. A mobile terminal according to claim 9 or 10, wherein:

said key locking control section releases a set key locked state when said control section determines that said aural signal and said character code are coincident.

14. A mobile terminal according to claims 9 or 10, wherein:

said control section determines plural times whether said aural signal and said character code are coincident or not.

15. A mobile terminal according to claim 9 or 10, wherein:

said key locking setting means is dial locking setting means.

16. A mobile terminal according to claim 9 or 10, wherein:

said mobile terminal is a mobile telephone.

17. A method of locking keys of a mobile terminal, wherein:

a desired character code is registered;

an aural signal is recognized;

determining whether the registered character code and the recognized aural signal are coincident or not; and

if said character code and said aural signal are coincident, key locking is set.

23. A locking method according to claim 17 or 18, wherein:

said key locking is dial locking.

18. A method of locking keys of a mobile terminal, wherein:

a desired character code is registered;

a response is made to an incoming call;

an aural signal is recognized when the response is made;

determining whether the registered said character code and the recognized said aural signal are coincident or not; and

if said aural signal and said character code are coincident, key locking is set.

19. A locking method according to claim 18, wherein:

determining by pressing a button whether said response is set or not.

20. A locking method according to claim 18, wherein:

a message showing that a response is made is sent when responding to said incoming call; and

after said message is sent, a state is switched to a recording state for recording said aural signal.

21. A locking method according to claim 18, wherein:

if said aural signal and character code are coincident, said key locked state is released.

22. A locking method according to claim 18, wherein:

determining plural times whether said aural signal and said character code are coincident or not.
