People with certain disabilities often have heavy disability accents. Their speech can sound very different from the way most nondisabled people speak.
People with disabilities that affect communication are often pushed into separate programs, particularly in adulthood. Even when they are in the same classes in the same schools, there isn’t much of an expectation that any peers listen to them. This was even more true a generation ago. As a result, most people without disabilities are lousy at understanding people with disability accents, and don’t understand that this is a glaring hole in their social skills.
Many unskilled people tend to maybe ask people with disability accents to repeat themselves once, and then they get frustrated and start ignoring them. Sometimes they pretend to understand, and smile and nod rather than actually listening. Sometimes they hang up on them. Sometimes they pass them off to another person, who also doesn’t bother to actually listen. Sometimes they hang up. If they are medical workers, sometimes they write on a chart that someone is impossible to understand or has no communication (particularly if that person also has an intellectual disability.)
Do not be this person. If you can’t understand someone with a disability accent, the problem is your skills, not their voice. (If you have a receptive language disability that prevents you from learning to understand accents, then it’s no one’s fault and you need an interpreter to communicate. Neither their voice nor your brain is wrong. In that situation, the skill you need to develop is finding an interpreter.)
If you listen, and make it clear that you are listening, you will learn to understand, and you will be able to communicate successfully with more people.
An important phrase for this is “I’m having trouble understanding what you’re saying, but I care what you are saying.”
Make sure it’s true, and keep listening. The more you listen, the easier it will be to understand. Understanding . And practice. You get better with practice.
Too many people are ignored because others can’t be bothered to understand their accents. You can make this better by listening (and by insisting that people you supervise listen.)
