What is Whisper API?
The OpenAI Whisper API is a cloud-based service that utilizes machine learning to convert audio or video files into text transcripts, falling under the Automatic Speech Recognition (ASR) category.
Whisper API's Key Features
Automatic Speech Recognition (ASR)
This core feature lies at the heart of Whisper's capabilities. It allows users to transcribe spoken language from audio or video files into text format. Whisper excels in this domain, achieving high accuracy even with challenging audio containing background noise, accents, or technical jargon.
Multilingual Support
Whisper isn't limited to just English. It boasts support for a wide range of languages, making it ideal for global applications. Users can transcribe audio in their native language or translate speech to English for broader accessibility.
Transcription Modes
The API offers two primary transcription modes – Transcription and Translation. Transcription mode delivers the spoken content in the original language it was recorded in, while Translation mode converts the speech to English text. This flexibility caters to diverse use cases.
Scalability and Efficiency
The cloud-based infrastructure of the Whisper API enables efficient processing of large audio/video files. This makes it a valuable tool for businesses dealing with significant volumes of speech data, such as call centers or media companies.
Optional Diarization (Speaker Identification)
For recordings with multiple speakers, Whisper offers optional diarization functionality. This feature separates the speech of each speaker into distinct transcripts, allowing for easier identification and analysis of individual contributions within a conversation.
Ease of Integration
The API employs a RESTful interface, a widely adopted standard for communication between applications. This simplifies integration for developers, enabling them to incorporate speech-to-text functionalities seamlessly into their projects.
Security and Privacy
While specific details may vary, OpenAI prioritizes user privacy and data security. Developers can expect secure access to the API and responsible handling of uploaded audio/video files.
In summary, the Whisper API offers a comprehensive suite of features for automatic speech recognition, catering to diverse needs. With its high accuracy, multilingual support, scalability, and optional functionalities like diarization, Whisper empowers developers and businesses to unlock the potential of speech data and streamline workflows.
Whisper API Pricing
OpenAI has made the Whisper AI to be paid, at a rate of $0.006 per minute. This means that it is not free for use.

Step 1 - Decide on Which Endpoint to Use
The Whisper API is integrated with other functionalities, such as creating speech from text, converting speech into text, and providing audio translation into English. This article will showcase Whisper API's main strength, which is converting audio files into text transcripts.
Step 2 - Download and Setup API request on Apidog
We will now use Apidog, an API tool, to view the text transcript produced by the Whisper API. Apidog provides developers with a simple and intuitive user interface for working with APIs - it cannot get easier and more enjoyable than this!
You can immediately copy the cURL code provided by OpenAI, and import it into Apidog.
Start by clicking the + button, and click the "Import cURL" button, as shown in the image above.
Next, copy and paste the cURL code for text transcription provided by OpenAI. If you cannot find it on the website, here is the same code:
curl https://api.openai.com/v1/audio/translations \
-H "Authorization: Bearer $OPENAI_API_KEY" \
-H "Content-Type: multipart/form-data" \
-F file="@/path/to/file/german.m4a" \
-F model="whisper-1"
You should now have a new API request in front of your screen. Proceed by changing the method from GET to POST. If you have the file that you want to replace in a different place, you can also modify the file row to the correct file path withinyour device.
Proceed by pressing the Headers section, and scroll down to Authorization. On this row, replace the $OPENAI_API_KEY with your OpenAI API Key.
Once you have finalized everything, you can click send. If done correctly, Apidog should produce a response such as:
{
"text": "Hello, my name is Wolfgang and I come from Germany. Where are you heading today?"
}
