Have you ever felt a mix of emotions you couldn't quite name? Or perhaps you thought you were fine, only to realize later that the fatigue was evident in your voice all along? We are often the last to notice the subtle shifts in our own emotional state until they build into something significant. A new technology is changing this, learning to listen to the words we don't say and sensing the emotional nuances that even we might miss. This is the power of NUNA’s MOOD feature—your personal, real-time emotion-sensing engine.

Voice, Rhythm, and Energy: Your Emotional Signature
We all know that what we say is important, but how we say it often reveals the deeper truth. NUNA’s multimodal AI engine is built on this insight. It doesn’t just analyze your words; it continuously analyzes your voice tone, speech rhythm, and energy levels.
- Is your tone high or low? This could reflect excitement or sadness.
- Is your speech pace fast or slow? This might hint at anxiety or calmness.
- Is the energy in your voice strong or faint? This can reveal confidence or exhaustion.
By capturing these non-verbal cues, NUNA senses the complex emotions hiding behind your words, painting a real-time, dynamic picture of your inner state.
The Unspoken Story: The Power of Millimeter-Wave Radar
Even more impressively, NUNA's perception goes beyond what it can hear. It utilizes advanced millimeter-wave radar technology to detect micro-changes in your body, completely contact-free. As you simply exist in the same space as NUNA, it sensitively captures the subtle fluctuations in your breathing and heart rate. These biosignals are the most honest expressions of emotion—your heart races when you’re nervous, and your breathing deepens when you’re relaxed. This technology allows you to be understood at the deepest level, all while you are in your most natural state, without wearing any device.
Words and Silence: The Rhythm of Your Mind
In addition to your voice and biosignals, NUNA pays attention to your "mental rhythm." It measures this through your word count and silence duration. Are you expressing yourself freely, or are you processing your thoughts in silence? Both states contain a wealth of information, reflecting whether your energy is directed outward in expression or inward in contemplation.
By combining all these layers—your words, your tone, your physiological signals, and your expressive rhythm—NUNA's MOOD feature acts as an incredibly perceptive companion. It offers an unprecedented window into your true emotional state, empowering you to truly begin understanding yourself, moment by moment.
