generating a DTMF command in accordance with the activated menu option.

2. The method of claim 1, wherein detecting an automated attendant is performed using voice recognition, and wherein speech recognition in respect of the incoming voice data is automatically activated in response to detecting an automated attendant.

3. The method of claim 1, wherein detecting an automated attendant is performed by the device user, and wherein speech recognition in respect of the incoming voice data is activated in response to predetermined input received via an input device of the mobile communication device.

4. The method of claim 1, further comprising:

determining a menu structure for the automated attendant in accordance with the DTMF commands; and

wirelessly uploading the menu structure to a remote data store in association with one or more of a telephone number or name of the automated attendant.

5. The method of claim 1, further comprising:

determining a menu structure for the automated attendant in accordance with the DTMF commands; and

storing the menu structure in a memory of the mobile communication device.

6. The method of claim 5, further comprising:

after detecting an automated attendant during a subsequent telephone call and before activating speech recognition, determining whether a menu structure for the automated attendant is stored in the memory of the mobile communication device;

wherein activating speech recognition and translating spoken prompts are performed when the menu structure for the automated attendant is not stored in the memory of the mobile communication device; and

wherein the displayed menu is based on a stored menu structure when the menu structure for the automated attendant is stored in the memory of the mobile communication device.

7. The method of claim 1, wherein menu options are automatically selected for a predetermined duration when the corresponding spoken prompts are reproduced by the automated attendant.

8. The method of claim 1, wherein the input activating a selected one of the menu options is depression of the touchscreen.

9. The method of claim 1, wherein the touchscreen is a depressible touchscreen and has a touch-sensitive input surface, the method further comprising:

selecting a first input mode or second input mode for receiving input activating a selected one of the menu options in accordance with respective input, wherein in the first input mode the input activating a selected one of the menu options is touch input via the touch-sensitive input surface, and wherein in the second input mode the input activating a selected one of the menu options is depression of the touchscreen.

10. The method of claim 9, wherein the input selecting the first input mode or second input mode is provided by a sensor configured to detect when the mobile communication device is held adjacent to an ear of a device user.

11. The method of claim 10, wherein the sensor is a proximity sensor, wherein the mobile communication device is configured to detect an object within a predetermined proximity of the touch-sensitive input surface in accordance with a proximity measurement detected by the proximity sensor.

12. The method of claim 10, wherein the sensor is a light sensor, wherein the mobile communication device is configured to detect an object located adjacent to the touch-sensitive input surface in accordance with an amount of light detected by the light sensor.

13. A method for generating dual-tone multi-frequency (DTMF) commands on a mobile communication device having a touchscreen, comprising:

detecting an automated attendant during a telephone call;

requesting and receiving DTMF commands in respect of the automated attendant in response to detecting an automated attendant;

displaying a menu having selectable menu options corresponding to the DTMF commands in a graphical user interface on the touchscreen;

receiving input selecting one of the menu options;

receiving input via the touchscreen activating a selected one of the menu options; and

generating a DTMF command in accordance with the activated menu option.

14. A method for generating dual-tone multi-frequency (DTMF) commands on a mobile communication device having a touchscreen, comprising:
