import { AssemblyAISTT } from "getpatter";

const stt = new AssemblyAISTT();                                  // reads ASSEMBLYAI_API_KEY
const stt2 = new AssemblyAISTT({ apiKey: "aa_..." });

Plug it into an agent:

// npx tsx example.ts
import { Patter, Twilio, AssemblyAISTT, ElevenLabsTTS } from "getpatter";

const phone = new Patter({ carrier: new Twilio(), phoneNumber: "+15550001234" });

const agent = phone.agent({
  stt: new AssemblyAISTT(),                           // ASSEMBLYAI_API_KEY from env
  tts: new ElevenLabsTTS({ voiceId: "rachel" }),      // ELEVENLABS_API_KEY from env
  systemPrompt: "You are a helpful assistant.",
});

await phone.serve({ agent });

For Twilio (mulaw 8 kHz) use AssemblyAISTT.forTwilio("aa_...").
