Do I Have a Speech Impediment? A 5-Minute Self-Check for Adults and Teens
A five-minute self-check can show whether one of your speech sounds is worth a closer listen: say a short word list, read a passage aloud, record it and listen back. An accent is not an impediment. Only a licensed speech-language pathologist can tell you whether a sound difference is a speech sound disorder.
The short answer: listen first, then ask a professional
“Speech impediment” is an everyday phrase for a few different things: a speech sound that’s made differently (like a lisp, or an R that sounds like W), stuttering, or a voice difference. This self-check is about speech sounds, the kind you can hear in single words. Stuttering is a different thing and has its own guidance.1,8
By the time you’re a teenager, every English consonant is past the age when it’s expected to be settled: a review of studies of U.S. children found all consonants acquired by about age 7 at a strict criterion. A sound that is still consistently different later on is usually called a residual or persistent speech error. It isn’t rare, and it isn’t a lost cause.5,6
A self-check can tell you which sound, if any, is worth a closer listen. Only a licensed speech-language pathologist (SLP) can tell you whether it’s a speech sound disorder, and what would help.1,4
The 5-minute self-check
- 1Find a quiet room and open your phone’s voice recorder. Hold the phone about a forearm’s length away.
- 2Say each word in the table below once, slowly and naturally. Don’t perform it; say it the way you would to a friend.
- 3Read the passage in the next section aloud at your normal speed.
- 4Listen back, ideally the next day, with headphones. Mark any sound that sounds different from how people around you say it, in more than one word.
- 5Look at the “accent or speech-sound difference?” table before you decide anything.
| Sound | Start | Middle | End | What to listen for |
|---|---|---|---|---|
| S | sun, sip | messy, pencil | bus, house | a TH sound (“thun”), a slushy or wet S, a whistle |
| Z | zoo, zip | busy, lazy | nose, buzz | the same as S, with the voice on |
| R | red, run | carrot, berry | car, four (if your English says this R) | a W sound (“wed”), or an R that sounds swallowed |
| TH | think, thumb | nothing, bathtub | bath, teeth | an F (“fink”) if your English normally has TH |
| L | lip, leaf | jelly, yellow | ball, feel | a W or Y sound (“wip”) |
| SH | shoe, ship | washing, fishing | fish, wash | a slushy sound, or an S in its place |
| CH | chair, chip | teacher, kitchen | watch, peach | a slushy sound, or SH or T in its place |
Words to record: the sounds that most often stay different past childhood, at the start, middle and end of a word.1
One word is not a pattern
Everyone mispronounces a word now and then. What matters is a sound that comes out the same different way across several words and positions.
Read this passage aloud
Single words are the easy part. Connected speech shows whether a sound holds up when you’re not thinking about it. Read this at your normal speed and record it:
Passage
Sarah’s brother Ross runs a small seaside shop that sells fresh fish and chips. Last Thursday, three hungry visitors arrived early, so he rushed to fill their order. Nothing was ready, but they laughed, sat in the sunshine, and shared a pot of tea while they waited.
Listen back for the same sounds as in the word list. If a sound was fine in single words but changes in the passage, note that too: it tells an SLP that the sound is there but not yet automatic.1
Accent or speech-sound difference?
Everyone has an accent, and an accent is not a communication disorder. A sound that follows the rules of your English is part of your accent. A speech sound difference is one that sounds different from your own community’s English, in your own words.2,3
| You notice | Usually an accent feature when… | Worth a closer listen when… |
|---|---|---|
| No R in “car” or “four” | your English is British, Australian or another English that drops R after a vowel | R is also missing or W-like at the start of words (“wed” for “red”) |
| T or D for TH (“tink”, “dat”) | your English uses T or D for TH, as many Englishes do | your English uses TH and you say F instead |
| A softer or different S | it matches how people around you say it | it sounds like TH, slushy or whistly in many words, in any accent |
| W for R | rarely: W for R isn’t a regular accent rule in most Englishes | it happens across words, past childhood |
Examples of accent features vs speech-sound differences. The difference is whether your own English does it.2

What your answers can and can’t tell you
- It can tell you which sound, if any, to listen to more closely, and whether it changes from single words to a passage.
- It can’t tell you why a sound is different, whether it’s a speech sound disorder, or what would help. That needs a speech-language pathologist.
- It can’t hear stuttering, voice or language differences well; those are separate questions for a professional.
Free Lisp Test
If your S or Z sounded different, the lisp test is a quick listening check of those two sounds. It is a preliminary screen, not a diagnosis.
If S or Z is the sound you noticed, go to the lisp self-check and the free lisp test. If it’s R, the page on R for adults explains why R is the sound most likely to stay different, and how adults practise it.

Next steps
Want a professional opinion? In the U.S., ASHA’s ProFind lists certified SLPs. In the UK, the RCSLT explains how to find a speech and language therapist, on the NHS or privately. Elsewhere, your country’s register of speech-language pathologists is the place to start.9,10
Want to practise a sound you noticed? Treatment research in teens and adults exists, most of it on R, and in a review of it, more intensive schedules tended to work better than occasional ones. Short, frequent practice is the part you can do at home.7
Happy with how you sound? That’s a legitimate choice. A speech difference only needs work if you want it to.

Frequently asked questions
How do I know if I have a speech impediment?＋
Start by listening to yourself. Say a short word list for the sounds that most often stay different (S, Z, R, TH, L, SH, CH), read a short passage aloud, record both and listen back the next day. If one sound is consistently different from how people around you say it, it’s worth a closer listen. Only a licensed speech-language pathologist can tell you whether it’s a speech sound disorder.
Is an accent a speech impediment?＋
No. ASHA is clear that accents, whether regional, foreign or nonnative, are not a communication disorder, and that everyone has an accent. A sound that follows the rules of your English, such as no R in “car” in British English, is part of your accent, not an error.
Can an online test tell me if I have a speech impediment?＋
No. An online check can help you notice a sound worth listening to, but it can’t see how your tongue moves, rule out an accent feature, or diagnose anything. A speech-language pathologist does that with an assessment.
Is a lisp a speech impediment?＋
A lisp is one kind of speech sound difference: the S and Z are made with the tongue or the air in a different place. If S and Z are the sounds you noticed, the lisp self-check and the free lisp test go into those two sounds in detail.
Can adults change a sound they’ve always said differently?＋
Many can. Speech sound differences that last past childhood are called residual or persistent errors, and treatment research in teens and adults exists, most of it on R. More intensive practice schedules tended to work better in a review of that research. Whether to work on a sound is your choice.
I’m a teenager. Can I do this check?＋
Yes. The self-check is just listening to yourself. If you want to practise afterwards, ask a parent to set up a free SpeechStep account; teens aged 13 to 17 practise through a parent’s account, and the practice itself is yours.
