# SpeechStep > 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 ## Start - [Free lisp check](https://speechstep.com/tools/lisp-assessment) - [Start practising (free account)](https://speechstep.com/practice) - [Pricing](https://speechstep.com/pricing) ## Learn more - [Why SpeechStep (how it differs)](https://speechstep.com/why-speechstep) - [How the AI feedback works](https://speechstep.com/how-ai-feedback-works) - [Speech practice apps compared](https://speechstep.com/speech-practice-apps-compared) - [Speech therapy vs a practice app](https://speechstep.com/speech-therapy-vs-speech-practice-app) - [Accents and speech sounds](https://speechstep.com/accents-and-speech-sounds) - [Speech therapy for adults](https://speechstep.com/speech-therapy-for-adults) - [Privacy policy](https://speechstep.com/privacy) ## 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. - Service catalogue (JSON): https://speechstep.com/ai/service.json · readable version: https://speechstep.com/ai - Contact: support@speechstep.com
