Your voice carries far more information than the words it produces. Research in affective computing and speech prosody has long established that vocal biomarkers — including pitch variation, speaking rate, pause patterns, and spectral energy — are reliable indicators of emotional states, cognitive load, and stress levels. Fenno builds on this science to create a personal voice mirror that reflects these invisible signals back to you.
Using on-device machine learning and Apple's speech analysis frameworks, Fenno extracts biometric features from your voice in real time: energy level, speaking pace, filler word frequency, sentiment trajectory, breathing rhythm, and voice steadiness. These signals are combined into a daily Pulse Score — a snapshot of how you're showing up today.
The Voice vs Words feature compares your vocal tone against the actual content of your speech using natural language processing. When your words say "I'm fine" but your voice says otherwise, Fenno catches the misalignment — a pattern most people never notice in themselves.
Nine Pattern Lenses — including Energy, Decision, and People — provide different angles for self-reflection over time. The Weekly Mirror aggregates your recordings into a gentle reflection of the week you just lived, surfacing trends in mood, energy, tension, and relational dynamics.
