Assuming you need a menu structure...
I haven't had the need to try this in GC, but in the past I've nested the additional options in a sub-menu. So on the main menu "1" would lead to a sub-menu (no audio) with a default exit for "1" and then "0", "1" and "2" would be effectively 10, 11, and 12.
Mentally whiteboarding this... Put all your speech activations in the main menu, along with all the audio prompts needed. Include a separate DTMF entry for "1" and build the additional entries off the sub-menu. Presume "check balance" is option 12. Your main menu has a speech activation choice for "check balance" and a separate DTMF menu choice for "1" and the sub-menu has a DTMF for "2." Both the main menu speech activation choice and the sub-menu "2" choice jump to the same balance checking code.
Not the prettiest solution, but in my head it could work. Might have overlooked something haven't tried anything like this in GC.
