Quantitative metrics such as Median Response Latency (typical time (in seconds) required to respond to a prompt), Mean Utterance Length (average number of words produced per response) and Elaboration Rate (degree to which responses are expanded beyond minimal answers) are kept for every session and compared to previous sessions.

We have metrics for over 700 user sessions. Please reach out to us for more information at info@elvoai.com.

These metrics provide objective measures of processing speed, verbal productivity, and conversational efficiency.

This metrics framework allows Elvo reports to include:
Objective performance data
Standardized qualitative ratings
Functional real-world interpretation
Clinician observations
User-centered outcomes

Together these create a comprehensive clinical reporting model.

Elvo will never replace a clinician, but rather assist with home carryover.

The efficacy of Elvo as a tool for use in any therapy has been substantiated with evidence. To date, Elvo-supported use has demonstrated clinically meaningful, diagnosis-appropriate outcomes across users with aphasia, Parkinson’s disease, mild cognitive impairment, and mixed cognitive-communication disorders.

Quantitative indicators—including response latency, conversational turn density, utterance regulation, and elaboration—show changes aligned with individualized clinical goals rather than uniform numerical directionality.
