SayPlay vs Articulation Lab

SayPlay is a private, on-device speech development tracker for parents and caregivers of young children. Tap record for 15 minutes a day. SayPlay listens, transcribes on-device, and quietly builds a picture of your child's vocabulary, talk-time, and developmental milestones. Nothing is ever uploaded. WHAT SAYPLAY DOES • Captures short audio sessions and transcribes them on-device using Apple's Speech framework. Audio and transcripts never leave your phone. • Tracks unique vocabulary against age-appropriate CDI norms (50% production age, currently English). • Logs CDC-style developmental milestones across language, social, emotional, and cognitive domains. • Celebrates first words with a shareable card you decide whether to share. • Surfaces talk-time trends, mean length of utterance, and tone mix per session. • Offers gentle Play activities — short, age-tuned prompts you hand the phone to your child for. • Filters non-target voices once you enroll your child's voice profile (three short clips, on-device only). PRIVACY BY DESIGN • 100% on-device speech recognition. SayPlay refuses to start if on-device dictation isn't available on your device — it will never silently fall back to Apple's servers. • No analytics. No tracking. No account. No login. No network requests. • Research export is opt-in, anonymized (name and birth date stripped), gated by a parental check, and saved to a file you control. • Wiping data is permanent and instant, also gated by a parental check. DESIGNED FOR FAMILIES • Warm, kid-friendly visuals — but built to clinical seriousness. Milestone framing matches CDC "Learn the Signs. Act Early." domain language. • Optional multi-child profiles. • Locale-aware: switches recognition to the child's home language where on-device support exists. • Accessible: VoiceOver labels, Dynamic Type, high-contrast colors. WHO IT'S FOR • Parents who want a longitudinal view of their child's words without uploading audio anywhere. • Speech-language pathologists and early-intervention clinicians looking for a parent-friendly bridge to milestone screening. • Researchers running ecologically valid speech development studies (with consenting families). WHAT SAYPLAY ISN'T SayPlay isn't a diagnostic tool. It surfaces patterns and prompts conversations with your pediatrician — it doesn't replace one.
