Build AI-Powered Transcription with Speaker Detection in Bubble
Ever wanted to automatically transcribe audio files and know exactly who said what? In this comprehensive Bubble tutorial, we dive into integrating the AssemblyAI API to generate transcripts with speaker labels - a game-changing feature for no-code app builders creating podcast platforms, meeting tools, or any audio-processing applications.
Setting Up Assembly AI API in Bubble's API Connector
The magic starts in Bubble's API Connector, where we configure the Assembly AI integration. This isn't just about basic transcription - we're unlocking advanced speaker identification capabilities that can distinguish between different voices in your audio files.
The setup involves configuring your API authentication with Assembly AI's private key, establishing the correct API endpoints, and most importantly, enabling the speaker_labels parameter that transforms basic transcription into intelligent speaker detection.
Understanding the Two-Step Assembly AI Workflow
Assembly AI operates on a sophisticated two-phase process that every Bubble developer should understand. First, you submit your audio file URL through a POST request, receiving a unique transcript ID in return. Then, you use this ID to retrieve the processed transcript containing both the full text and detailed speaker information.
This asynchronous approach is perfect for Bubble workflows, allowing your app to handle audio processing without blocking user interactions. The key is understanding how to structure your API calls and manage the response data effectively.
Processing Speaker-Labeled JSON Responses
The real power emerges when Assembly AI returns your transcript data. Beyond the standard text output, you receive structured JSON containing "utterances" - individual speaking segments with speaker identification. Each utterance includes the spoken text, timestamp information, and speaker labels that allow you to recreate conversations with perfect attribution.
This structured data opens up possibilities for creating dynamic conversation displays, speaker analytics, and interactive transcript experiences that would typically require complex backend development.
What's Coming in Part 2
While Part 1 focuses on API integration and data retrieval, Part 2 will demonstrate how to process this speaker-labeled data through Bubble's database system. You'll learn to store, organize, and display conversation segments in ways that create compelling user experiences.
