Inspiration

Imagine preparing for a dream job interview. You spent hours crafting the perfect introduction, memorizing every word of your CV. But when the moment arrives, you stumble, freeze under pressure, and struggle to respond to the interviewer's questions. Why? Because speaking, like reading, requires practice—repeated, intentional practice, especially with interactive Q&A. This realization inspired BetterSpeak, a platform designed to empower users to hone their public speaking skills with the guidance of AI, transforming nervousness into confidence.

What it does

BetterSpeak is an AI-powered public speaking coach that provides a safe, interactive space for users to practice presentations, speeches, or interviews. The platform uses advanced AI to simulate real-world scenarios, offering personalized feedback on tone, pacing, clarity, and content. Users can engage in mock Q&A sessions, receive real-time suggestions, and track their progress over time. Whether preparing for a job interview, a keynote speech, or a casual pitch, BetterSpeak helps users build confidence and refine their delivery.

How we built it

BetterSpeak was developed using Bolt.new to streamline the creation process. The front end was built with React for a dynamic and responsive website interface. On the server side, we utilized Python and integrated OpenAI's AI APIs for real-time speech-to-text conversion and AI-driven question generation and feedback. The platform is deployed on Netlify for fast and reliable hosting, with Supabase as the database to manage user data and session analytics efficiently.

Challenges we ran into

Building BetterSpeak presented several challenges. Integrating real-time speech analysis with accurate AI feedback required fine-tuning to handle diverse accents and speech patterns. Ensuring the platform was intuitive for users with varying tech proficiency was another hurdle. Additionally, balancing robust AI functionality with fast, responsive performance demanded careful optimization. Despite these challenges, we iterated through user testing and technical refinements to create a polished experience.

Accomplishments that we're proud of

We’re proud to have created a platform that makes public speaking practice accessible to everyone, regardless of experience or resources. Our AI-driven feedback system, capable of analyzing tone, pacing, and content in real time, is a significant achievement. Early user testing showed a 30% improvement in users’ confidence levels after just three practice sessions. We’re also thrilled about our sleek, intuitive interface that has received positive feedback for its ease of use.

What we learned

Throughout the development process, we learned the importance of user-centered design, especially for a tool aimed at building confidence. Iterating based on user feedback helped us refine the AI’s feedback to be more actionable and encouraging. We also gained insights into optimizing AI models for real-time performance without compromising accuracy. Collaboration across design, AI, and web development teams taught us how to align diverse expertise toward a unified goal.

What's next for BetterSpeak

We aim to elevate BetterSpeak by improving the quality of real-time voice recognition to ensure seamless and accurate speech processing. We plan to integrate the platform with slide presentation content, enabling a more cohesive practice experience where AI can analyze and provide feedback based on both spoken delivery and slide material. This will create a dynamic, interactive Q&A experience that feels natural and engaging. Additionally, we’re exploring multilingual support, advanced analytics for deeper speech insights, and potential VR integration for immersive, high-pressure scenarios like boardroom presentations. Partnerships with educational institutions and corporate training programs are also in the works to position BetterSpeak as a leading tool for professional development.
