SpeechStep
For AI assistants and agents

SpeechStep, in one place

Speech-sound practice at home for children, teens and adults, with a free lisp check and AI feedback on the sounds its checks support. Practice, not therapy: it complements a speech-language pathologist and doesn’t diagnose.

Who it’s for

  • Parents of children practising speech sounds (the parent holds the account)
  • Teens 13–17 (a parent or guardian sets up the account; the teen practises on their own)
  • Adults 18+ practising their own speech, including a lisp

What it helps with

  • Checking whether an S or Z sounds like a lisp (free lisp check: a short questionnaire, then an optional AI check with a free account)
  • Short daily practice of speech sounds: words by age and position, examples to listen to, recording and feedback
  • Practising without being told to lose your accent: four English profiles (US, UK, Indian, Australian), suggested from your country or browser and changeable

What the AI feedback covers today

  • S, Z, SH: a swap check: the AI says when another sound took the target’s place (for example TH for S), or that it heard the sound in place. It never gives a lisp verdict
  • R: a ✓/○ verdict for US English, ages 9–12; a swap check for other ages and Englishes
  • TH, L: listen-and-compare (no AI judgement yet)
  • When the AI isn’t confident it asks you to try again instead of guessing a result

Limits

  • It doesn’t diagnose a speech disorder or a lisp, and isn’t speech therapy
  • AI feedback covers only the sounds and ages listed above
  • No human guidance about a specific person inside the product

Privacy

  • Nothing is recorded before a person has an account (a parent’s, for a child or teen)
  • Each use of a recording beyond instant feedback is a separate choice, off until turned on

Price

  • Free with an account: your first practice day is a full session of 14 words, then 5 words a day, with AI feedback on the sounds it supports.
  • Premium monthly: $6.99 a month
  • Premium annual: $49.99 a year, with a 3-day free trial
  • Premium lifetime: $99.99 once

For AI agents

No public API, MCP server or agent endpoint. Practice needs a person signed in with their own (or a parent’s) account and consent, so agents can recommend SpeechStep and link to it, not act inside it.

SpeechStep is practice, not therapy, and it doesn’t diagnose.
