Inspiration
Whether you're hanging out with friends, feeling bored at home, or on a long car ride -- singing is often something we find ourselves reaching to. One of the members of our team (Fiona) really enjoys singing and so we thought it would be a nice idea to look into how she can sound better so that she, and everyone else around her can better enjoy her voice. We wanted to create a tool that allows singers to practice anywhere, with real time advice. Vocal lessons are often very expensive and being able to take these lessons and sing is often viewed as a privilege. Hence, to dispel all these beliefs and help everyone like Fiona improve their singing, we've created VocalAI -- an artificial-intelligence based software that can generate you a karaoke version of any song provide you real time feedback of your singing.
What it does
VocalAI, our innovative platform, offers two key features that aim to enhance your singing experience. With VocalAI, you can enjoy the convenience of transforming any song into a personalized karaoke track. Whether you're practicing your favorite tunes or planning to perform them, VocalAI seamlessly creates high-quality karaoke versions that align perfectly with the original compositions.
In addition to karaoke creation, VocalAI incorporates advanced speech recognition technology to ensure you're singing the right words. Our powerful speech recognition algorithms analyze your vocal delivery and compare it to the original lyrics, providing real-time feedback and guidance to ensure accurate pronunciation and word alignment. This feature helps you develop proper diction and ensures that your performance stays true to the original song.
Furthermore, VocalAI includes a valuable scoring system designed to evaluate your pitch accuracy while singing. By analyzing your vocal performance, our intelligent algorithms provide constructive feedback and precise scoring based on your pitch accuracy. This feature allows you to track your progress over time, identify areas for improvement, and refine your singing abilities.
With VocalAI, you have access to an all-in-one platform that combines karaoke creation, speech recognition, and pitch scoring to elevate your singing experience. Whether you're a beginner seeking to improve or an experienced vocalist aiming for perfection, VocalAI provides the tools and guidance you need to unlock your full singing potential.
How we built it
VocalAI was built using a carefully selected combination of technologies to deliver a seamless singing experience. Here's why we utilized each tool:
React
We chose React for its ability to build dynamic and responsive user interfaces, ensuring a smooth and interactive experience for VocalAI users.
Tailwind CSS
To expedite the development process and maintain visual consistency, we opted for Tailwind CSS. Its utility-first approach provided us with a comprehensive set of pre-built components and styles.
Flask
Flask, being lightweight and flexible, was an ideal choice for building the server-side components of VocalAI. It allowed us to handle various functionalities such as song processing, user authentication, and scoring algorithms.
