Deepgram Hello World

Overview

Minimal working example demonstrating core Deepgram speech-to-text functionality.

Prerequisites

Completed deepgram-install-auth setup
Valid API credentials configured
Audio file for transcription (or use URL)

Instructions

Step 1: Create Entry File

Create a new file for your hello world example.

Step 2: Import and Initialize Client

import { createClient } from '@deepgram/sdk';

const deepgram = createClient(process.env.DEEPGRAM_API_KEY);

Step 3: Transcribe Audio from URL

async function transcribe() {
  const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
    { url: 'https://static.deepgram.com/examples/nasa-podcast.wav' },
    { model: 'nova-2', smart_format: true }
  );

  if (error) throw error;
  console.log(result.results.channels[0].alternatives[0].transcript);
}

transcribe();

Output

Working code file with Deepgram client initialization
Successful transcription response
Console output showing transcribed text

Error Handling

Error	Cause	Solution
Import Error	SDK not installed	Verify with `npm list @deepgram/sdk`
Auth Error	Invalid credentials	Check environment variable is set
Audio Format Error	Unsupported format	Use WAV, MP3, FLAC, or OGG
URL Not Accessible	Cannot fetch audio	Ensure URL is publicly accessible

Examples

TypeScript - Transcribe URL

import { createClient } from '@deepgram/sdk';

const deepgram = createClient(process.env.DEEPGRAM_API_KEY);

async function main() {
  const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
    { url: 'https://static.deepgram.com/examples/nasa-podcast.wav' },
    { model: 'nova-2', smart_format: true }
  );

  if (error) throw error;
  console.log('Transcript:', result.results.channels[0].alternatives[0].transcript);
}

main().catch(console.error);

TypeScript - Transcribe Local File

import { createClient } from '@deepgram/sdk';
import { readFileSync } from 'fs';

const deepgram = createClient(process.env.DEEPGRAM_API_KEY);

async function transcribeFile(filePath: string) {
  const audio = readFileSync(filePath);

  const { result, error } = await deepgram.listen.prerecorded.transcribeFile(
    audio,
    { model: 'nova-2', smart_format: true, mimetype: 'audio/wav' }
  );

  if (error) throw error;
  console.log('Transcript:', result.results.channels[0].alternatives[0].transcript);
}

transcribeFile('./audio.wav');

Python Example

from deepgram import DeepgramClient, PrerecordedOptions
import os

deepgram = DeepgramClient(os.environ.get('DEEPGRAM_API_KEY'))

options = PrerecordedOptions(
    model="nova-2",
    smart_format=True,
)

url = {"url": "https://static.deepgram.com/examples/nasa-podcast.wav"}
response = deepgram.listen.rest.v("1").transcribe_url(url, options)

print(response.results.channels[0].alternatives[0].transcript)
