const ws = new WebSocket("wss://api.brainiall.com/v1/audio/stream", {
  headers: { Authorization: `Bearer ${API_KEY}` }
});

ws.send(JSON.stringify({ config: { language: "en", interim_results: true } }));
audioSource.on("data", (chunk) => ws.send(chunk));

ws.on("message", (data) => {
  const result = JSON.parse(data);
  console.log("Transcript:", result.text, "Confidence:", result.confidence);
});

Sprecherdiarisierung

POST/v1/audio/diarize
