Campbell Connor, an undergraduate student majoring in economics at the University of Chicago, had always been passionate about helping people unlock their full potential. While navigating the competitive world of academia and professional development, she noticed a recurring obstacle: the pervasive use of filler words like "um," "like," and "you know," which often undermined the clarity and credibility of even the most brilliant ideas. Recognizing the power of clear and confident communication as the cornerstone of career success, she set out to find a solution.
Campbell's lightbulb moment came when she realized that the key to improving communication lay not in after-the-fact corrections, but in real-time awareness. Inspired by the immediate feedback methods used in organizations like Toastmasters, she envisioned a tool that would discreetly alert users to their filler word usage in the moment, allowing them to adjust their speech and develop more professional habits naturally.
With this vision in mind, Campbell created Credible, a groundbreaking mobile app designed to deliver real-time haptic feedback whenever a filler word is detected. Unlike other products that rely on practice sessions or focus solely on virtual platforms like Zoom, Credible integrates seamlessly into everyday conversations, empowering users to improve their communication skills on the go. The app is powered by machine learning, adapting to each individual's voice for unparalleled accuracy and effectiveness.
Campbell's mission for Credible is simple yet profound: to help everyone be judged by the quality of their thoughts rather than the distractions in their delivery. By eliminating excessive filler words, users can convey their ideas more coherently, boosting their confidence and professional image in interviews, presentations, and beyond.

The custom machine learning models at the heart of Credible are designed to deliver real-time, personalized filler word detection while maintaining privacy and efficiency by operating entirely on the user’s device. Here’s how they work and contribute to Credible's unique functionality:
Voice Recognition Model:
This model continuously listens and identifies the user's voice, distinguishing it from other speakers and background noise. This ensures that Credible only monitors and provides feedback on the intended user's speech.
Filler Word Detection Model:
A dedicated algorithm detects filler words like "um," "like," and "you know" in real-time. It is trained on diverse data to recognize common filler words across different accents, speech patterns, and tones.
Personalization through Machine Learning:
The app uses adaptive learning to tune its models specifically to each user's speech habits. This allows Credible to identify personalized filler words or phrases that the user chooses to add, increasing its relevance and effectiveness.
On-Device Processing:
All the machine learning models run locally on the device, ensuring that no speech data is stored or sent to the cloud. This guarantees total privacy while also providing instantaneous feedback without lag.
Haptic Feedback Integration:
Once a filler word is detected, the app integrates seamlessly with the device’s haptic feedback system to deliver a discreet vibration alert. This real-time feedback enables users to become immediately aware of their speech habits without interrupting the flow of their conversation.
