        echo "{
  \"config\": {
    \"auto_decoding_config\": {},
    \"language_codes\": [\"en-US\"],
    \"model\": \"long\"
  },
  \"content\": \"$(base64 -w 0 /full/path/to/audio/file.wav | sed 's/+/-/g; s/\//_/g')\"
}" > /tmp/data.txt

      2. Gunakan curl untuk membuat permintaan recognize:

        curl -X POST -H "Content-Type: application/json; charset=utf-8" \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -d @/tmp/data.txt \
    https://speech.googleapis.com/v2/projects/PROJECT_ID/locations/global/recognizers/_:recognize

        Anda akan melihat respons seperti berikut:

          {
    "results": [
      {
        "alternatives": [
          {
            "transcript": "how old is the Brooklyn Bridge",
            "confidence": 0.98267895
          }
