Disclaimer.

dol. is not a medical device, not a diagnostic tool, not therapy, not mental-health treatment, and not professional speech coaching. The drills and prototypes are experimental. We don’t claim any clinical outcome.

If you have a question about your voice, your speech, your child’s speech, your mental health, or your wellbeing — please talk to a qualified professional. dol. is a place to practice, not a place to be diagnosed.

The kids prototypes (Echo Island, Sing-Song Stories, Voice Costume Box, Tap the Word) draw on evidence-based pediatric speech-language-pathology techniques — Hanen, Lidcombe, PROMPT, Melodic Intonation Therapy. They are not a substitute for evaluation or treatment by a licensed speech-language pathologist (SLP). If a child shows persistent speech, language, or communication difficulties, please consult a qualified professional. These prototypes work best alongside an SLP, not instead of one.

We don’t collect data about children. The prototypes are designed to be used with an adult nearby. For users under 13, please follow the anonymous flow (no account) — see privacy.

When a drill counts your filler words, measures your words-per-minute, times how long it took you to start speaking, or tracks how much your volume dropped — those numbers are rough, browser-side approximations. They are intended for self-reflection and habit-building. They are not a diagnosis. A clinical-grade evaluation would use calibrated audio equipment, trained listeners, and validated instruments. We use a JavaScript engine in your browser.

Audio recordings stay on your device by default. We don’t upload your voice or your video. There is no cloud media sync today (it is planned — and when it ships, it will be explicit, opt-in, and optional).

Some drills use your browser’s built-in speech recognition (Web Speech API) to provide live transcripts and word counts. Depending on your browser, that feature may transmit short snippets of audio to the browser vendor’s speech provider (e.g., Google on Chrome, Apple on Safari). We do not store those transcripts. We do not send them anywhere ourselves. If this concerns you, you can use the drill without enabling transcription — the audio still records locally.

See privacy for the full picture.

Prompts that invite affirmations, mantras, or self-talk are not promises. We can’t guarantee any health, career, relationship, or wellbeing outcome from saying anything out loud. The point is practice, not magic.
