@spekoai/client

Browser SDK for SpekoAI — real-time voice conversations in the browser.

Install

npm install @spekoai/client
# or
pnpm add @spekoai/client

Quick start

Create a session from your backend (see POST /v1/sessions), then start a conversation from the browser:

import { VoiceConversation } from '@spekoai/client';

const conversation = await VoiceConversation.create({
  transportToken, // from your server's POST /v1/sessions response
  transportUrl,   // from your server's POST /v1/sessions response

  onConnect: ({ conversationId }) => console.log('connected', conversationId),
  onDisconnect: ({ reason }) => console.log('disconnected', reason),
  onMessage: ({ source, text, isFinal }) => console.log(source, text, isFinal),
  onStatusChange: (status) => console.log('status', status),
  onModeChange: (mode) => console.log('mode', mode), // 'listening' | 'speaking'
  onError: (err) => console.error(err),
});

Controlling the session

await conversation.setMicMuted(true);
conversation.setVolume(0.8);
conversation.sendUserMessage('hello');
conversation.sendContextualUpdate('user switched to the checkout page');

await conversation.endSession();

API

VoiceConversation.create(options)

options must contain short-lived session credentials minted by your backend. Do not pass Speko API keys to browser code.

conversationToken and livekitUrl are still accepted as legacy aliases.
