This is a submission for the AssemblyAI Challenge : Really Rad Real-Time.

What I Built

I built SpeakSync, a real-time transcription application that transforms live audio streams into actionable insights using AssemblyAI's Streaming API. SpeakSync is designed to elevate live interactions in various contexts, including:

Virtual Meetings: Providing real-time captions and keyword highlights.
Live Events: Generating instant transcriptions for accessibility and post-event summaries.
Customer Support: Offering real-time analysis of customer interactions to improve agent performance.
Key features include:

Real-Time Transcription: Converts live audio streams into text instantly.
Live Keyword Highlights: Dynamically displays important keywords as they are spoken.
Sentiment Tracking: Detects sentiment in live conversations, enabling immediate insights.

Journey

To implement the Streaming API from AssemblyAI, I followed these steps:

Integration with AssemblyAI:

Utilized the Streaming API to receive text in real time from live audio streams.
Configured the application to handle low-latency data streams for a seamless user experience.
Additional Tools for Enhancement:

Sentiment Analysis: Used AssemblyAI’s sentiment detection feature to monitor the tone of conversations.
Keyword Spotting: Incorporated real-time keyword extraction to display important terms dynamically on the UI.
Frontend and Backend Setup:

Frontend: Built using React, focusing on a clean, real-time updating interface.
Backend: Used Node.js to manage the audio streams and API requests efficiently.
Handling Edge Cases:

Addressed noisy audio and overlapping speakers by using AssemblyAI's advanced audio processing capabilities.

Challenges Faced
Latency Optimization:
Worked on reducing latency to ensure real-time transcription matched the spoken words without noticeable delays.

Speaker Overlap:
Integrated logic to flag and manage instances where multiple speakers talked simultaneously.

User Scalability:
Designed the backend to handle concurrent users and multiple audio streams efficiently.

Future Plans
Integrating translation capabilities for multilingual real-time transcription.
Developing mobile support for event organizers and remote teams.
Adding an offline transcription feature for recorded streams.

This was an individual submission, but special thanks to the developer community for providing invaluable feedback during testing.
