What should a 4-year-old be able to say?

The CDC's four-year checklist says most children say sentences of four or more words, say some words from a song, story or nursery rhyme, tell you about at least one thing that happened during their day, and answer simple questions like “What is a coat for?” Those four items are the core of a 4-year-old speech checklist.

Which sounds should a 4-year-old be able to say?

By four, p, b, m, h, w, d, n and t should be solid, and k, g, f, y and ng should be in or nearly in. S, z, l, sh, ch, j and v arrive between four and six, and r and th are not expected until five to eight. So “wabbit” at four is normal, and “tat” for “cat” is the one worth mentioning.

How clear should a 4-year-old's speech be?

Clear enough that strangers understand almost everything, in ASHA's words “understandable in conversation,” even with a few late sounds still wrong. If adults outside the family regularly have to ask you what your child said, that is a reason for an assessment at four.

Is a lisp normal at 4?

Common, yes. S and Z are due between four and six, so a four-year-old saying “thun” for “sun” is inside the normal range. It becomes worth working on around five, and worth an assessment if it is still there at six or seven, or if the tongue pushes out between the teeth on most sounds. How to fix a lisp in a child covers what works at home.

Is it normal for a 4-year-old to stutter?

Easy repetitions (“I-I-I want”) are common between two and five and most children grow out of them. Stuttering with visible effort, tension, long blocks, or a child who starts avoiding words or talking is different, and worth seeing a speech-language pathologist about early. Fluency therapy works best before school age.

When should I worry about my 4-year-old's speech?

Act early if your child is not using sentences, is usually hard for strangers to understand, still gets early sounds wrong (p, b, m, t, d, n, k, g), stutters with effort, cannot follow a two-step instruction, cannot tell you about their day, or has lost skills. Ask your doctor for a hearing test and a referral to a speech-language pathologist.

Can an app help a 4-year-old's speech?

Four is the age it starts to. A four-year-old can copy a sound on request and sit for a short game, which is what sound practice needs. Apps do the repetition between therapy sessions; Help Me Talk scores each attempt and tracks the sound over weeks, which helps a parent who cannot tell a good K from a nearly-good one. No app replaces the assessment if the checklist above came out thin.

Checklist

The 4-year-old speech checklist for your child

Four is the year the checklist changes shape. Under three the question was “are the words coming?”; at four it is “can they use them?”: sentences, stories, answering a real question, and being understood by the teacher on the first day of pre-K. This page is the CDC's own four-year list, the sounds that should be in place by now (and the ones people wrongly panic about), and the specific signs that are worth an appointment.

A four-year-old boy on a porch step tells a story with his hands to his grandfather, who listens from a bench with a mug of tea.

The short answer

The CDC's checklist for four says a typical child says sentences of four or more words, says some words from a song, story or nursery rhyme, tells you about at least one thing that happened during their day, and answers simple questions like “What is a coat for?” By four, strangers should understand nearly everything they say. Early sounds (p, b, m, t, d, n, k, g, f) should be in. R, TH and often S are still allowed to be wrong.

The talking checklist at four: four things to tick off

These are the language and communication milestones the CDC lists for age four, checked on 6 September 2026. As with every CDC list since 2022, they describe what 75% or more of children can do, so a tick is “doing what most children do” rather than “top of the class.”

Judge on an ordinary week, not a good day.

Says sentences with four or more words. “I want the blue cup” counts. Sentences do not have to be grammatical yet; “Me goed park” is four words and a real sentence at this age.
Says some words from a song, story or nursery rhyme. Joining in with the end of a line, or getting most of “Twinkle Twinkle” out. This is memory for language, and it is what later reading is built on.
Talks about at least one thing that happened during their day, like “I played soccer.” Ask at dinner. It takes real language to hold an event in mind and report it, which is why the CDC lists it.
Answers simple questions like “What is a coat for?” or “What is a crayon for?” This tests whether they can explain rather than name. “For cold” is a pass.

The sounds that should be there at four

This is where parents most often worry about the wrong thing. The sounds due by four are the early and middle ones. The late sounds, which are the ones everyone notices (“wabbit”, “thoup”), are not expected until five or later. The ages below are the Iowa–Nebraska norms, the same ones the app uses to suggest which sound to work on.

At four	Sounds	What it means at home
Should be solid	p, b, m, h, w, d, n, t and the vowels	The one- to three-year sounds. If any of these are still wrong at four, mention it: they are the easiest to fix and the least likely to fix themselves.
Should be in, or nearly	k, g, f, y, ng	Due between three and four. “Tat” for “cat” at four is worth a look; at three it was normal.
Arriving between four and six	s, z, l, sh, ch, j, v	A lisp at four is common. It is the age to start noticing, not the age to worry.
Not due until five to eight	r, th	“Wabbit” and “fank you” at four are entirely normal. R is the last sound in English.

How clear should a four-year-old be?

Clear. ASHA's milestones for four to five put it as: “produces most consonants correctly, and speech is understandable in conversation.” The usual clinical rule is that a stranger understands roughly all of what a four-year-old says, even with a few sounds still wrong.

The test is other adults, not you. If a grandparent, a nursery worker or a friend's parent regularly has to ask you what your child said, that is the sign, and it is one of the best-established reasons to get an assessment at this age. Unclear speech at four has a way of becoming teasing at five and reluctance to speak up at six.

The signs to take to a doctor

The CDC's guidance is the same at every age: if your child is not meeting one or more milestones, has lost skills, or you have other concerns, act early. At four the specific things worth an appointment are:

Not speaking in sentences, or sentences that are mostly two or three words.
Strangers usually cannot understand them. Not “sometimes”; usually.
Early sounds still wrong: p, b, m, t, d, n, k, g, or leaving the ends off words.
Stuttering that is getting worse, with visible effort, tension or avoidance. Easy repetitions at three and four are common and usually pass; struggle is different. See an SLP early; fluency work is most effective before school.
Cannot follow a two- or three-step instruction (“get your shoes and put them by the door”).
Has lost words, sentences or skills they had.
Cannot answer simple questions or tell you about their day even in short form.

What helps at four

Four is the age daily practice starts to work properly, because a four-year-old can copy a sound on request and sit for five minutes if it is a game. For language, the CDC's own suggestions are to use grown-up words in conversation, read together and ask what will happen next, and use sequence words (“first”, “then”, “finally”) during routines.

For sounds, pick the one sound from the table above that should be in and is not, and work on that alone for a few weeks. Every sound has a free page on this site with mouth-position instructions, word lists and three games. If you want the attempts scored rather than judged by ear, that is what Help Me Talk (our app) does: your child says the word, the app scores it, and the per-sound progress over weeks tells you whether it is moving. It is built for roughly ages two to ten and four is the sweet spot. $6.99 a month or $39.99 a year, on iPhone, iPad and Android, with a 3-day trial.
