A podcast transcript API automates this process. With the right setup, you'll streamline your workflow and reclaim hours of production time. This guide shows you how to use Cleanvoice API to automate your transcription workflow. We'll cover everything from setup to implementation.

But first…

What Is a Podcast Transcription API?

A podcast transcription API converts podcast audio into written text automatically. Rather than manual transcription, users upload audio files and receive machine-generated transcripts through API requests. The system uses speech recognition and natural language processing to accurately transcribe content.

The API handles speaker identification, keyword detection, and audio cleanup—removing background noise, filler words ("um" or "uh"), and stutters.

For example, Cleanvoice's podcast transcription API, for example, takes this a step further by offering additional features such as:

  • Multi-language transcription across 60+ languages
  • Filler word removal for cleaner transcripts
  • Noise reduction for improved audio clarity

This automation lets podcasters maintain high-quality, SEO-friendly transcripts while focusing on content creation.

How to Set up a Podcast Transcription API

Step 1: Choose the Right API Service

For this tutorial, we’ll be using our Cleanvoice API, a powerful tool that offers automatic transcription, filler sound removal, and various export options.

We also provide a free trial, allowing you to test the service before committing to our flexible pay-as-you-go or subscription pricing.

Step 2: Sign Up for Cleanvoice

To get started, visit theCleanvoice AI website and sign up for an account. After signing up, you’ll be able to access your API key, which is necessary for making requests to the Cleanvoice API.

Step 3: Authenticate with the API

Once you have your API key, you can authenticate your requests. Every API call must include your API key in the header. Here's how to do it:

curl "https://api.cleanvoice.ai/v2/account" \

 -H "X-API-Key: your\_api\_key\_here"

Replace your_api_key_here with your actual API key from your account settings.

Step 4: Upload Your Podcast Audio File

You can upload your podcast file in one of two ways:

Option 1: Via Public URL

If your audio file is publicly accessible, you can upload it directly by providing the URL. The API will download the file from the URL automatically.

For example:

"files": ["https://yourdomain.com/podcast.mp3"]

Option 2: Direct Upload

If you prefer to upload your audio directly to Cleanvoice servers, follow these steps:

Step 4.1:  Request a signed URL for uploading your file.

curl -X 'POST' \

  'https://api.cleanvoice.ai/v2/upload?filename=audio.mp3' \

  -H 'X-API-Key: your\_api\_key\_here'

This will return a signed URL for uploading your file to Cleanvoice’s R2 Cloudflare bucket.

Step 4.2: Use the signed URL to upload your audio file.

curl -X PUT -T audio.mp3 -L "https://signed-url..."

Step 5: Create a New Edit for Transcription

Once your file is uploaded, you can create an edit request to start the transcription process. Use the following command to submit your request:

curl -X POST "https://api.cleanvoice.ai/v2/edits" \

  -H "X-API-Key: your\_api\_key\_here" \

  -H "Content-Type: application/json" \

  -d '{

    "input": {

      "files": [

        "https://public.com/podcast.mp3"

      ],

      "config": {

        "transcription": true

      }

    }

  }'

This command will create a transcription edit for your audio file. The API will automatically process the file, remove filler words, and transcribe it.

Step 6: Retrieve Your Transcription

To check if the transcription is complete, use the following command:

curl "https://api.cleanvoice.ai/v2/edits/<ID>" \

  -H "X-Api-Key: your\_api\_key\_here"

Once the transcription is finished, you’ll receive a JSON response with a link to download the edited file, along with the transcription.

Step 7: Export and Download the Transcription

After the transcription process is complete, you can download the results using the provided download_url. The Cleanvoice API also supports exporting the transcription in various formats such as MP3, WAV, FLAC, and more.
