Build fluency through daily practice
Flowen listens as you speak and gives you instant feedback — showing you whether your speech onset was gentle or tense, and how to improve it. Built on the evidence-based techniques used in clinical speech therapy.
3 free sessions included · No card required
650,000 adults in the UK stammer. Most wait over a year for NHS speech therapy.
Stammering affects approximately 1% of adults worldwide. In the UK, NHS waiting lists for speech and language therapy routinely exceed 12 months — and most programmes offer only infrequent, brief sessions. Between appointments, there is almost nothing evidence-based to practice with. Flowen fills that gap: daily, structured practice with real-time feedback, available from day one.

Every layer of the Flowen stack is optimised for the sub-100ms round-trip required to deliver effective biofeedback during live speech.
Acoustic Biofeedback Engine
We detect the exact moment you begin speaking so we can tell you immediately whether your onset was gentle or tense. Amplitude, fundamental frequency, and a jitter/shimmer-based vocal tension index are all measured and streamed in real time.
Precision Viseme System
A 3D avatar mirrors your mouth movements in real time, matched to phoneme groups derived from acoustic analysis. Easy-onset overlays guide air flow, lip position, and laryngeal relaxation simultaneously.
DCB0129 Safety Framework
Immutable consent audit ledger, GDPR Article 9 data erasure pipeline, and UK data residency enforce clinical governance at every layer. All voice biomarkers are processed on-device.
Simple, transparent pricing
For individuals, clinicians, and organisations — including Access to Work, NHS, and DSA funding pathways.
