Simple Integration
Get started with just a few lines of code
// Speech-to-Text Example
import { VagaryVoice } from '@vagary/voice-sdk';
const client = new VagaryVoice({
apiKey: process.env.VAGARY_API_KEY
});
// Transcribe audio file
const result = await client.transcribe({
audio: audioFile,
language: 'en-US',
enableDiarization: true
});
console.log(result.transcript);
// Text-to-Speech Example
const audio = await client.synthesize({
text: 'Hello from Vagary Voice!',
voice: 'en-US-Neural-Female',
emotion: 'friendly'
});
// Real-time streaming
