Have you considered using an s/key-like system to make these hashes more

   WOW-SCAN-NAVE-AUK-JILL-BASH-HI-LACE-LID-RIDE-RUSE-LINE-GLEE-WICK-A
...which is a little longer, but speaking of branch "wow-scan" (which 
gives 22 bits of disambiguation) is probably less error-prone than 
discussing branch '461...' (only 12 bits).

You could supercharge this algorithm by using (say) 
/usr/dict/american-english-large (>2^17 words; 160 bits of hash = 10 
dictionary words), or mixing upper and lower case (likely to reduce the 15 
word s/key phrase to ~11 words) to give something like
    RiDe-Rift-rIMe-rOSy-ScaR-sCat-ShiN-sIde-Sine-seeK-TIEd-TINT
My personal feeling is that case is likely to be dropped in casual 
conversation, so speaking of branch 'wow', 'wow-scan', or 'wow-scan-nave' 
is likely to be significantly more useful than trying to pronounce 
mixed-cased versions of these.

This is obviously a cogito issue, rather than a git-fs thing.
