# AssemblyAI Hello World ## Overview Minimal working examples demonstrating AssemblyAI's three core capabilities: async transcription, audio intelligence features, and LeMUR (LLM-powered analysis). ## Prerequisites - Completed `assemblyai-install-auth` setup - Valid API key configured in `ASSEMBLYAI_API_KEY` ## Instructions ### Step 1: Basic Transcription (Remote URL) ```typescript import { AssemblyAI } from 'assemblyai'; const client = new AssemblyAI({ apiKey: process.env.ASSEMBLYAI_API_KEY!, }); async function transcribeUrl() { const transcript = await client.transcripts.transcribe({ audio: 'https://storage.googleapis.com/aai-web-samples/5_common_sports_702.wav', }); if (transcript.status === 'error') { throw new Error(`Transcription failed: ${transcript.error}`); } console.log('Transcript:', transcript.text); console.log('Duration:', transcript.audio_duration, 'seconds'); console.log('Word count:', transcript.words?.length); } transcribeUrl().catch(console.error); ``` ### Step 2: Transcribe a Local File ```typescript async function transcribeLocal() { // The SDK handles upload automatically when you pass a local path const transcript = await client.transcripts.transcribe({ audio: './recording.mp3', }); console.log('Transcript:', transcript.text); // Access word-level timestamps for (const word of transcript.words ?? []) { console.log(`[${word.start}ms - ${word.end}ms] ${word.text} (${word.confidence})`); } } ``` ...
