Abstract

A portable computer with a speech recognition function and the method for processing a speech command thereof is disclosed. In the method of a speech command, the speech command has Y command character strings, wherein Y is a positive integer and which is greater than or equal to one. The method includes a step: providing a plurality of speech recognition databases and loading a corresponding speech recognition database responding to execute the X-th command string of the speech command, wherein X is a positive integer and is greater than or equal to one and is less than or equal to N. When the string corresponding to the X-th command character string is found in the loaded speech recognition database, an operation designated by the X-th command string is executed, and when X is not equal to Y, one is added to X.

Claims

1. A method for processing a speech command, the speech command comprising Y command strings wherein Y is a positive integer and is greater than or equal to one, the method comprising:

providing a plurality of speech recognition databases;

loading a corresponding database from the speech recognition databases responding to execute an X-th command string of the speech command, wherein X is a positive integer and is greater than or equal to one and is less than or equal to Y;

determining whether the loaded speech recognition database has a string corresponding to the X-th command string;

executing an operation designated by the X-th command string when the string corresponding to the X-th command string is found in the loaded speech recognition database; and

adding one to X when X is unequal to Y.

2. The method according to claim 1, wherein the method is terminated when X is equal to Y.

3. The method according to claim 1, wherein when the loaded speech recognition database does not have a string corresponding to the X-th command string, the executing of the speech command is abandoned.

4. The method according to claim 1, wherein the speech command comprises n characters, and n is a positive integer.

5. The method according to claim 4, wherein the step of determining whether the loaded speech recognition database has a string corresponding to the X-th command string comprises:

combining all characters between the k-th to the m-th characters of the speech command in sequence to generate a combined string, wherein k is a positive integer and is greater than or equal to one and is less than m, and m is a positive integer and is greater than k and is less than or equal to n;

searching whether the corresponding speech recognition database has a string corresponding to the combined string in the corresponding speech recognition database;

regarding the combined string as the X-th command string when the string corresponding to the combined string is found in the corresponding speech recognition database;

determining whether m is equal to n when the string corresponding to the combined string is not found in the corresponding speech recognition database;

adding one to m when m is not equal to n, and regenerating the combined string; and

abandoning executing of the speech command when m is equal to n.

6. The method according to claim 1, wherein executing the operation designated by the X-th command string comprises one of executing an application program and accessing a data file.

7. The method according to claim 1 further comprising checking determining whether a speech recognition function is started up.

8. A portable computer with a speech recognition function comprising:

an input unit for receiving a speech command;

a storage unit storing a plurality of speech recognition databases; and

a processing unit coupled to the input unit and the storage unit,

wherein when the speech recognition function is started up and a speech command having N command strings is inputted from the input unit, the processing unit loads a corresponding speech recognition database from the storage unit responding to execute an X-th command string of the speech command and searches whether the corresponding speech recognition database has a string corresponding to the X-th command string in the corresponding speech recognition database, and when the string corresponding to the X-th command string is found in the loaded speech recognition database, the operation designated by the X-th command string is executed, and one is added to X when X is not equal to N, and N is a positive integer and is greater than or equal to one, and X is a positive integer and is greater than or equal to one and is less than or equal to N.

9. The portable computer according to claim 8, wherein the input unit is a directional microphone.

10. The portable computer according to claim 8, wherein the storage unit is a hard disk drive.

11. The portable computer according to claim 8, wherein the processing unit comprises a temporary storage area for storing the loaded speech recognition databases.

12. The portable computer according to claim 8 further comprising a memory unit coupled to the processing unit and be used to store the speech recognition databases.

13. The portable computer according to claim 12, wherein the memory unit is a dynamic random access memory.

14. The portable computer according to claim 8, wherein the processing unit executes an application program stored in the storage unit according to the X-th command string.

15. The portable computer according to claim 8, wherein the processing unit executes an operation that accesses a data file for the storage unit according to the X-th command string.
