How to Use Gladia

  1. Start Transcription: Send an initial request to the Gladia API with the audio URL.
  2. Poll for Results: Use the result URL to check the transcription status.
  3. Retrieve Transcription: Once completed, retrieve the full transcript.

Example code (python):

async function makeFetchRequest(url: str, options: any):
  const response = await fetch(url, options);
  return response.json();

async function pollForResult(resultUrl: str, headers: any):
  while (true):
    console.log("Polling for results...");
    const pollResponse = await makeFetchRequest(resultUrl, { headers });

    if (pollResponse.status === "done"):
      console.log("- Transcription done: \n ");
      console.log(pollResponse.result.transcription.full_transcript);
      break;
    else:
      console.log("Transcription status : ", pollResponse.status);
      await new Promise((resolve) => setTimeout(resolve, 1000));

async function startTranscription():
  const gladiaKey = "YOUR_GLADIA_API_TOKEN";
  const requestData = {
    audio_url:
      "YOUR_AUDIO_URL",
  };
  const gladiaUrl = "https://api.gladia.io/v2/transcription/";
  const headers = {
    "x-gladia-key": gladiaKey,
    "Content-Type": "application/json",
  };

  console.log("- Sending initial request to Gladia API...");
  const initialResponse = await makeFetchRequest(gladiaUrl, {
    method: "POST",
    headers,
    body: JSON.stringify(requestData),
  });

  console.log("Initial response with Transcription ID :", initialResponse);

  if (initialResponse.result_url):
    await pollForResult(initialResponse.result_url, headers);
