THE PROBLEM

A place to practise between everyday conversations.

Flowen brings speech exercises, microphone-based feedback and session history into one browser-based practice space. Use it at your own pace. If you need assessment or treatment, speak to a qualified Speech and Language Therapist.

HOW THE PRODUCT WORKS

Feedback while you practise

The browser analyses microphone audio to display live feedback. Timing and signal quality depend on your device, browser and environment; no end-to-end latency guarantee is published.

Acoustic Biofeedback Engine

Microphone audio drives visual cues based on acoustic features such as amplitude and pitch. These estimates support practice; they are not clinical measurements of vocal tension or a diagnosis.

Live visual cues16kHz PCM

Avatar demonstration

Explore animated mouth shapes in the avatar demonstration. During AI conversation, avatar motion is driven by the AI voice audio, not a clinical measurement of your mouth or larynx.

Privacy and safety information

Read how Flowen handles recordings, audio processing and account data. Some features send audio to service providers or store recordings. Clinical safety documents remain drafts; this is not a claim of NHS approval or certification.

Begin daily practice

Explore guided practice stages and exercises. The exercises are not a personalised clinical treatment plan.

Track your progress

Review saved session summaries, practice activity and stage completion in your dashboard. Automated scores are estimates, not validated clinical outcomes.

Clinician tools

The platform includes clinician interfaces for assigned accounts. Access requires an appropriate clinician relationship and account permissions; a subscription does not supply a therapist.
