OpenAI Whisper supports multiple languages and can transcribe files in various formats, including MP3, WAV, and MP4.

AssemblyAI

AssemblyAI is another popular transcription platform that offers high-quality transcription services. It is a cloud-based service that can be integrated into various applications using APIs. AssemblyAI supports multiple languages and can transcribe files in various formats, including MP3, WAV, and MP4. AssemblyAI also offers additional features, such as speaker diarization and sentiment analysis.

Setting Up API Authentication

Before integrating OpenAI Whisper or AssemblyAI into your application, you need to set up API authentication. This involves creating an account, obtaining an API key, and setting up API credentials.

OpenAI Whisper API Authentication

To set up API authentication with OpenAI Whisper, follow these steps:

Create an account on the OpenAI Whisper website.
Obtain an API key by going to the API keys page.
Set up API credentials by creating a new API key or using an existing one.
Note down the API key and API secret.

AssemblyAI API Authentication

To set up API authentication with AssemblyAI, follow these steps:

Create an account on the AssemblyAI website.
Obtain an API key by going to the API keys page.
Set up API credentials by creating a new API key or using an existing one.
Note down the API key and API secret.

Implementing a Function to Send Audio Files and Receive Transcripts

Once you have set up API authentication, you can implement a function to send audio files and receive transcripts. This involves using the API to send audio files and retrieve transcripts.

OpenAI Whisper Function

Here is an example of a function that sends an audio file to OpenAI Whisper and receives a transcript:

import requests

def transcribe_audio(file_path, api_key, api_secret):
    # Set up API credentials
    headers = {
        'Authorization': f'Bearer {api_key}',
        'Content-Type': 'application/json'
    }

    # Set up API endpoint
    endpoint = 'https://api.openai.com/v1/whisper'

    # Set up audio file
    audio_file = open(file_path, 'rb')

    # Send audio file to API
    response = requests.post(endpoint, headers=headers, data=audio_file)

    # Check if response is successful
    if response.status_code == 200:
        # Get transcript from response
        transcript = response.json()['text']

        # Return transcript
        return transcript
    else:
        # Return error message
        return f'Error: {response.status_code}'

# Example usage
file_path = 'audio_file.mp3'
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

transcript = transcribe_audio(file_path, api_key, api_secret)
print(transcript)

AssemblyAI Function

Here is an example of a function that sends an audio file to AssemblyAI and receives a transcript:

import requests

def transcribe_audio(file_path, api_key, api_secret):
    # Set up API credentials
    headers = {
        'Authorization': f'Bearer {api_key}',
        'Content-Type': 'application/json'
    }

    # Set up API endpoint
    endpoint = 'https://api.assemblyai.com/v2/transcript'

    # Set up audio file
    audio_file = open(file_path, 'rb')

    # Send audio file to API
    response = requests.post(endpoint, headers=headers, data=audio_file)

    # Check if response is successful
    if response.status_code == 200:
        # Get transcript from response
        transcript = response.json()['text']

        # Return transcript
        return transcript
    else:
        # Return error message
        return f'Error: {response.status_code}'

# Example usage
file_path = 'audio_file.mp3'
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

transcript = transcribe_audio(file_path, api_key, api_secret)
print(transcript)
