Download Whisper AI: A Free and Powerful Speech Recognition Tool by OpenAI
Speech recognition is a critical component of many modern applications, from voice-activated assistants to automated customer service systems. However, developing and deploying a reliable and accurate speech recognition system can be challenging and costly. That's why OpenAI, a research organization dedicated to creating and promoting beneficial artificial intelligence, has developed and open-sourced Whisper AI, a general-purpose speech recognition model that can handle various tasks such as multilingual speech transcription, speech translation, and language identification. In this article, we will introduce you to Whisper AI, explain how it works, and show you how to download and use it for your own projects.

What is Whisper AI?
Whisper AI is an automatic speech recognition (ASR) system trained on a large dataset of diverse audio collected from the web. It uses a Transformer sequence-to-sequence model that can predict a sequence of tokens corresponding to the input audio. These tokens can represent different tasks such as language identification, phrase-level timestamps, multilingual speech transcription, and to-English speech translation. By using special tokens as task specifiers or classification targets, Whisper AI can perform multiple tasks with a single model, replacing many stages of a traditional speech-processing pipeline.
How does Whisper AI work?
Whisper AI works by splitting the input audio into 30-second chunks, converting them into log-Mel spectrograms, and passing them into an encoder. The encoder produces a sequence of hidden states that are fed into a decoder. The decoder then generates a sequence of tokens that represent the output text. The tokens are intermixed with special tokens that indicate the task to be performed or the information to be provided. For example, the token <lang> indicates that the next token should be the language code of the input audio, such as en for English or es for Spanish. The token <ts> indicates that the next token should be the timestamp of the current phrase in seconds. The token <trans> indicates that the following tokens should be the translation of the input audio into English.

Robustness: Whisper AI is trained on a large and diverse dataset of 680,000 hours of multilingual and multitask supervised data collected from the web. This makes it more robust to accents, background noise, and technical language than other models that are trained on smaller or more closely paired datasets.
Multilingualism: Whisper AI can transcribe and translate speech in multiple languages, including English, Spanish, French, German, Chinese, Hindi, Arabic, and more. It can also automatically identify the language of the input audio and switch between tasks accordingly.
Simplicity: Whisper AI is a simple end-to-end approach that does not require any preprocessing or postprocessing steps. It can directly convert raw audio into text or translation without any intermediate representations or modules.
Openness: Whisper AI is open-sourced by OpenAI under the MIT license, which means anyone can use it for free and modify it as they wish. OpenAI also provides models, inference code, model card, paper, and blog post to help developers and researchers understand and use Whisper AI.
How to download and install Whisper AI?
To use Whisper AI, you need to download and install it on your system. There are different ways to do that, depending on your preference and system configuration. Here are some of the most common methods: Downloading Whisper AI from GitHub
One way to download Whisper AI is to clone the GitHub repository that contains the source code and the models. To do that, you need to have Git installed on your system. You can check if you have Git by typing git --version in your terminal. If you don't have Git, you can install it from . Once you have Git, you can clone the Whisper AI repository by typing the following command in your terminal:
git clone
This will create a folder called whisper in your current directory, where you can find the source code and the models.
Installing Whisper AI with pip
Another way to download and install Whisper AI is to use pip, a package manager for Python. To do that, you need to have Python and pip installed on your system. You can check if you have Python by typing python --version in your terminal. If you don't have Python, you can install it from . Once you have Python and pip, you can install Whisper AI by typing the following command in your terminal:
pip install whisper-ai
This will download and install Whisper AI and its dependencies on your system.
Installing ffmpeg as a dependency
Whisper AI requires ffmpeg, a tool for converting audio formats, as a dependency. You need to install ffmpeg on your system before using Whisper AI. You can check if you have ffmpeg by typing ffmpeg -version in your terminal. If you don't have ffmpeg, you can install it by following the instructions from . The installation process may vary depending on your operating system.
How to use Whisper AI?
Once you have downloaded and installed Whisper AI, you can use it for various speech recognition tasks. There are different ways to use Whisper AI, depending on your preference and use case. Here are some of the most common methods:
Using Whisper AI from the command line
You can use Whisper AI from the command line by using the whisper-cli tool that comes with the package. To use it, you need to provide an input audio file and an output text file as arguments. You can also specify the task to be performed by using special tokens as prefixes or suffixes. For example, to transcribe an English audio file called input.wav and save the output text as output.txt, you can type the following command in your terminal:
whisper-cli input.wav output.txt <lang>en</lang>
This will tell Whisper AI to identify the language of the input audio as English and transcribe it accordingly. You can also use other tokens such as <ts>, <trans>, or <lang> with different language codes to perform other tasks such as timestamping, translation, or language identification. For more details on how to use whisper-cli, you can type whisper-cli --help in your terminal.
Using Whisper AI from Python code
You can also use Whisper AI from Python code by importing the whisper module that comes with the package. To use it, you need to create a Whisper object and call its recognize method with an input audio file and an output text file as arguments. You can also specify the task to be performed by using special tokens as prefixes or suffixes. For example, to translate a Spanish audio file called input.wav into English and save the output text as output.txt, you can write the following Python code:
import whisper w = whisper.Whisper() w.recognize("input.wav", "output.txt", "<trans>< lang>es</lang>")
This will tell Whisper AI to identify the language of the input audio as Spanish and translate it into English accordingly. You can also use other tokens such as <ts>, <trans>, or <lang> with different language codes to perform other tasks such as timestamping, transcription, or language identification. For more details on how to use the whisper module, you can refer to the documentation at .
Using Whisper AI from a web interface
If you don't want to install Whisper AI on your system, you can also use it from a web interface that is hosted by OpenAI. To use it, you need to visit the website at and upload an audio file or record your voice. You can then choose the task to be performed from a drop-down menu and click on the "Recognize" button. You will see the output text on the screen, along with the option to download it as a text file or copy it to the clipboard. You can also share the output text with others by using a unique link that is generated for each session.
