I'm sure you will be fine. Just three days into my return to work I had to speak to a group of about 30 appointees to the governor's higher ed innovation commission, plus another 30-40 audience members, with a voice not much more than a hoarse whisper. No problem. In most situations, even if people don't know your story, they will simply accept your limitation on move on. As your voice heals, which we will be positive and assume it will, things will get easier. If it doesn't improve, there are some things that can be done.
I went through three vocal fold injections over a year. They helped noticeable for a week or two and then fell off. Just as I went in to consult about something a bit more permanent, my voice began show noticeable signs of improvement - that was at the one-year post-surgery mark. I still have some limitations in that I can't really sing more than a few notes in a row most days without coughing and I can't yell very well, especially outside.
If I had to call cadence, I couldn't without ongoing coughing fits. Most days there are no significant issues at four-years post.
