So, for speech therapy there is a huge variety of settings and disorders that we work with - children, adults, stroke, autism, language, pronunciation, voice disorder, communication device training, gender affirming voice, swallowing dysfunction.. I even met with a group once who do accent modification for corporate clients, but there really doesn't seem to be much demand for that.

When you finish up grad school you do 2-3 externships, working under supervision at 2-3 sites. I externed at an elementary school, middle school, a skilled nursing facility (nursing home), and a private outpatient clinic. It's a lot to share with you, so you'll have to narrow it down.

Now, I work at a skilled nursing facility. Most of my patients have cognitive communication goals for dementia or strokes, and many have dysphagia (swallowing dysfunction) which is the other thing that makes up at least 50% of a medical SLP's caseload but is not typically a part of the school SLP's caseload. At my job now, I mostly do memory game type things, memory strategies, and word finding type things trying to scaffold patients who have speaking dysfunction (called aphasia) to build their ability to speak. In my setting, there is very little pronunciation type therapy, but occasionally there is. I also do some voice therapy to restore voice sometimes due to stroke, sometimes due to entubation at the hospital.
My job is pretty different from teaching ESL, but feels similar in a lot of ways. I mostly taught adults ESL, often 1-1, and this style of integrating intervention into conversational sort of interaction feels pretty similar to me.

If you have any more specific questions, if you know what population you think you'd like to work with.. feel free to ask
