A short guided conversation on a phone or laptop is analysed across four signal streams. A cross-modal transformer combines them into one risk score and shows which signals contributed most.

## Key takeaways

- A short guided conversation on a phone or laptop.
- Speech, language, facial movement and background information are analysed together.
- A cross-modal transformer combines them into one explainable risk score.

## From conversation to clinician review

1. **Conversation.** A short guided conversation
2. **Four streams.** Speech timing and voice; Language; Facial movement; Background information
3. **Model.** Cross-modal transformer
4. **Risk score.** Shows which signals contributed most
5. **Clinician review.** A clinician decides who should be seen sooner

## A conversation

A short guided conversation on a phone or laptop. It is low-burden, and it is designed to feel like a conversation rather than a test. The conversation is designed for everyday devices: a phone or a laptop.

## Speech timing and voice

Speech timing and voice: pauses, rate, rhythm and fluency. These parts of speech carry across languages.

## Language

Language: vocabulary, structure and coherence. Existing screening was largely designed around one language and culture. Nurevo is built for multilingual populations from the start.

## Facial movement

Facial movement during the conversation.

## Background information

Background information: age, education and other context.

## The model

A cross-modal transformer combines the four streams into one risk score. The streams are analysed together, rather than as separate results that a person must reconcile.

## The risk score

The risk score shows which signals contributed most. A clinician can see what informed the result. That is what we mean by explainable by design.

Illustrative example. These marks are not a result.

## Clinician review

The risk score helps clinicians decide who needs specialist assessment first. A clinician can see what informed the result.

## What it is not

Nurevo is a screening and triage tool in development. It is not a diagnostic device and is not currently available for clinical use.
