You can edit it right in the doc or leave comments, and I'll revise. It downloads as a PDF or Word file.\n\nThe age chart uses the Crowe & McLeod (2020) review of U.S. children. It also points out where ASHA lists earlier ages, so parents can see that norms vary by source. You'll probably want to add your school SLP's name and email to the \"How to ask\" line.\n\n----- ARTIFACT CONTENT (Claude Docs: \"How Kids Learn Speech Sounds\") -----\n\nHow Kids Learn Speech Sounds\nKids learn speech sounds a few at a time, from about age 1 to age 7. Easy sounds like /p/, /b/, and /m/ come first. Harder sounds like /s/, /r/, and \"th\" can take until age 5, 6, or even 7. Mistakes along the way are normal. This sheet shows the usual ages. It is a guide, not a test.\nWhich sounds most kids can say, and when\nBy about age\nSounds\nTry words like\n3\np, b, m, d, n, h, w\npop, ball, mom, dog, no, hi, wet\n4\nt, k, g, f, y, ng\ntop, cat, go, fish, yes, sing\n5\ns, z, sh, ch, j, l, v\nsun, zoo, shoe, chip, jump, lip, van\n6\nr, \"th\" as in this, \"zh\" as in treasure\nred, this, treasure\n7\n\"th\" as in think\nthink, bath\nAges come from a 2020 review of 15 U.S. studies of almost 19,000 children (Crowe & McLeod). Many kids say a sound well before the age shown.\nHow easy your child should be to understand\n• By age 3: family and friends understand most of what your child says.\n• By age 4 to 5: most people, even strangers, understand your child.\nSaying \"wabbit\" for \"rabbit\" or \"nana\" for \"banana\" is normal when kids are young. It matters more if it keeps going as they get older.\nWhen to talk to the school speech-language pathologist (SLP)\nReach out if your child:\n• is still hard for teachers or other kids to understand at age 4 or older\n• still can't say sounds from the chart a year or more after the age shown\n• often leaves off the start or end of words (\"ca\" for \"cat\")\n• gets upset, is teased, or stops talking because of how they sound\n• has had many ear infections, or you wonder about their hearing\nYou can also ask just because you are worried. You know your child best.\nHow to ask: Email or call your child's teacher or the school SLP. Write down a few words your child says differently. You can ask in writing for a free school speech evaluation.\nGood to know: An accent, a dialect, or learning two languages is not a speech problem. Kids learning more than one language may learn some sounds earlier or later.\nWhere these ages come from\nDifferent experts give slightly different ages. That is because studies test different kids, in different ways, and use different cutoffs. For example, ASHA lists /t, k, g, f/ by age 3, a year earlier than the chart above. ASHA also says it is okay for 4-year-olds to still mix up s, sh, ch, j, l, r, and th. So use these ages as a rough guide, not a deadline.\nSources\n• Crowe, K., & McLeod, S. (2020).
