Flowen
Technical overview
A description of the current code, not a clinical validation paper or a measured performance benchmark.
Browser audio analysis
The web capture hook uses Web Audio and an AudioWorklet. It requests microphone access and passes 16 kHz PCM frames to subscribers. The frame size is a processing configuration, not measured microphone-to-screen latency.
Detection and transcription
The repository contains acoustic feature extraction and rule-based disfluency detection. Transcription is a separate path. The current production implementation and configured providers must be checked before any deployment-specific claim. This page makes no claim of a proprietary trained ASR model, training-corpus size or measured precision, recall or F1.
Avatar animation
The avatar demonstration exposes mouth-shape states. In AI conversation the animation follows the AI audio; it is not a validated measurement of the user's articulation.
Performance and evaluation
No repeatable end-to-end benchmark is published here. Previous sub-80ms and under-300ms claims are withdrawn pending measurement across supported devices and defined test conditions. No Flowen-specific clinical outcome study is presented.
Clinical safety status
The repository contains clinical safety documents and a hazard log labelled as controlled drafts. Drafts do not prove signed clinical approval, DCB0129 compliance, completed DTAC assessment, DSPT status or NHS procurement readiness.
Read safety informationAudio and privacy
Live acoustic analysis runs in the browser. Depending on the feature, audio may also be transmitted to service providers or stored as a session recording. Read the privacy policy for the disclosed processing, recipients, retention and your choices. Do not assume that all voice data stays on your device.

Flowen is a speech practice tool. It does not diagnose, treat or cure stammering, and does not replace assessment or care from a qualified Speech and Language Therapist. Automated feedback is an estimate. Clinical effectiveness, funding approval and NHS endorsement are not established by this page.
