Sparrow-0
Sparrow is a transformer-based model designed for dynamic, natural conversation. It picks up on tone, rhythm, semantic meaning, and subtle conversational cues — adapting in real time with an intuitive, human-like flow.
Unlike traditional AI models that treat dialogue as rigid back-and-forth exchanges (leading to awkward pauses and interruptions), Sparrow thrives in both rapid-fire debates and thoughtful discussions.
The result? Conversations that feel fluid, engaging, and remarkably lifelike.
"Before Sparrow-0, AI would interrupt or lag, making conversations feel really awkward. Now, they adapt to each user’s rhythm, making mock interviews flow effortlessly. Our users engage longer, have more in depth conversations, and get a practice experience that truly prepares them for the real thing."
50%
Sparrow-0’s natural conversations encourage users to speak more, fostering deeper, richer interactions.
80%
Users stay significantly longer in conversations powered by Sparrow-0, compared to traditional high-sensitivity pause methods.

Customize AI Conversation Flow with Precision
Sparrow-0 is fully configurable to match different conversation styles, pacing, and interaction needs. Developer controls allow fine-tuning of turn-taking behaviors, pause sensitivity, and activation triggers. Whether you’re building a patient AI tutor or a fast-talking AI SDR, you can set the conversation style to suit the use case.Â
Conversational Awareness
Understands semantic meaning, tone, and pacing to determine exactly when to respond—just like a human.
Turn Sensitivity & Control
Understands the natural rhythm of human speech by capturing subtle cues and respecting pauses, ensuring each interaction feels remarkably human.
Heuristics & ML
Dynamically adapts to speaking styles and conversation patterns using conversational heuristics and machine learning.
Optimized Latency
Delivers ultra-fast response times under 600ms for seamless, real-time conversation.
Learning when to speak
Sparrow-0's transformer-based approach refines its response timing over each conversation, learning from each interaction to match natural conversation flow. Humans talk differently, Sparrow-0 dynamically responds.
