Speech recognition is not underlining and providing alternate interpretations
While it's unclear if you asking as development perspective or for using only. Knowing about the app /more information could be useful.
Here's a few information for you:
If development - yes, Google voice recognition returns more than one match. I think development is not reflected on question.

If app is showing only the first one/ result only then please check if it has the functionality to enable such feature(other results). 

Thanks.
