Hi! I have a wee habit of mumbling and I stumble over spoken English since I have a mild accent. I work in retail so I know very basic ASL but not enough to carry a conversation that is not small talk. Sometimes when talking to deaf/hoh customers, I try to to enunciate my words a bit more so lip reading can be easier (safely of course). My co-worker noticed this and told me it to wrong to do so. I'm a bit worried that it is ableist and if I should stop. If it is, what else can I do to help?
speaking more clearly is very helpful for lip-reading folks, but it depends on how you go around it. You should not exxagerate to comical degree, should not cut words into smaller chunks, or make your speech sound unnatural.
So, careful pronunciation is good, but overexaggerating can be seen as patronising and is actually not helpful - it makes lip-reading harder.
I can’t really say where your speech falls into without seeing it. The best “material” for lip-reading is to try to voice the word without sound (that way you concentrate more on a lip-shapes), but on the other hand, lot of folks are hard of hearing and need the loud words to understand, so.
The best way to communicate with deaf customers is to respect their communication needs. Follow their cues. If they watch your lips, they are likely lip-reading, if they get out a phone or pen/paper, they want to write, some just want to use gestures, some have hearing enough left to understand if you speak clearly.
