Gladia.io offers an API powered by AI models to transcribe and comprehend audio/video files. The Quick Start page provides a brief overview of our services.

Our dedicated team is available to assist with any inquiries related to our API, features, or documentation. You can contact us on discord.

Getting your API key

First, you need to create a Gladia account.

Go to https://app.gladia.io and create an account using your email and password, or using your Google account. This will bring you to your home dashboard where you can find your API key.

Making your first API call

here are several ways to make an API call.

Using Curl

As you can already see in the graphic interface in https://app.gladia.io, you can make transcription requests yourself using different languages. This is a curl request using audio-transcription:

curl -X 'POST' \
    'https://api.gladia.io/audio/text/audio-transcription/' \
    -H 'accept: application/json' \
    -H 'x-gladia-key: <your_api_key>' \
    -H 'Content-Type: multipart/form-data' \
    -F "audio_url=http://files.gladia.io/example/audio-transcription/split_infinity.wav"

You can now open a terminal and copy/paste the snippet containing your own API key.

Using other languages (Python, JavaScript, Php, ...)

You can make requests using any languages you want.
Here, we will see an example using audio-transcription in different languages and libraries:

import requests

headers = {
    'accept': 'application/json',
    'x-gladia-key': '<your_api_key>',
}

files = {
    'audio_url': (None, 'http://files.gladia.io/example/audio-transcription/split_infinity.wav')
}

response = requests.post('https://api.gladia.io/audio/text/audio-transcription/', headers=headers, files=files)

import fetch, { FormData } from 'node-fetch';

const form = new FormData();
form.append('audio_url', 'http://files.gladia.io/example/audio-transcription/split_infinity.wav');

fetch('https://api.gladia.io/audio/text/audio-transcription/', {
    method: 'POST',
    headers: {
        'accept': 'application/json',
        'x-gladia-key': '<your_api_key>',
        'Content-Type': 'multipart/form-data'
    },
    body: form
});

const axios = require('axios');
const FormData = require('form-data');

const form = new FormData();
form.append('audio_url', 'http://files.gladia.io/example/audio-transcription/split_infinity.wav');

const response = await axios.post(
    'https://api.gladia.io/audio/text/audio-transcription/',
    form,
    {
        headers: {
            ...form.getHeaders(),
            'accept': 'application/json',
            'x-gladia-key': '<your_api_key>',
            'Content-Type': 'multipart/form-data'
        }
    }
);

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.gladia.io/audio/text/audio-transcription/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'accept' => 'application/json',
    'x-gladia-key' => '<your_api_key>',
    'Content-Type' => 'multipart/form-data',
]);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
    'audio_url' => 'http://files.gladia.io/example/audio-transcription/split_infinity.wav',
]);

$response = curl_exec($ch);

curl_close($ch);

🚧
As in the previous part, do not forget to replace '<your_api_key>'.

Using the CLI (Command-Line Interface)

The Gladia CLI is a command-line interface tool that allows developers to transcribe audio files or URLs using the Gladia API. It supports several features such as noise reduction, speaker diarization, direct translation, text emotion recognition, and summarization.

🚧
At the time where this is being written, only audio-transcription is supported.

First, you need to download the following repository: https://github.com/gladiaio/gladia-cli

Authentication

To authenticate, be sure to have an API key. Run the following if you want to save the key:

./gladia_cli --gladia-key MY_GLADIA_KEY --save-gladia-key

or use it inline for each request:

./gladia_cli --gladia-key MY_GLADIA_KEY --OTHER_OPTIONS ...

How to use the CLI

  -audio-file string
    	Path to the audio file
  -audio-url string
    	URL of the audio file
  -diarization
    	Enable diarization

			(default "automatic multiple languages")
  -noise-reduction
    	Enable noise reduction
  -output-format string
    	Output format (table, csv, json, srt, vtt, txt) (default "table")
  -save-gladia-key
    	Save Gladia API key
  -transcription-hint string
    	Transcription hint
