Model overview
The whisper-medium.en model is an English-only version of the Whisper pre-trained model for automatic speech recognition (ASR) and speech translation. Developed by OpenAI, Whisper models demonstrate a strong ability to generalize to many datasets and domains without the need for fine-tuning. The model was trained on 680k hours of labelled speech data using large-scale weak supervision.
Similar models in the Whisper family include the whisper-tiny.en, whisper-small, and whisper-large checkpoints, which vary in size and performance. The whisper-medium.en model sits in the middle of this range, with 769 million parameters.
Model inputs and outputs
Inputs
- Audio waveform as a numpy array
- Sampling rate of the input audio
Outputs
- Text transcription of the input audio, in the same language as the input
- Optionally, timestamps for the start and end of each transcribed text chunk
Capabilities
The whisper-medium.en model exhibits improved robustness to accents, background noise, and technical language compared to many existing ASR systems. It can also perform zero-shot translation from multiple languages into English. The model's accuracy on speech recognition and translation tasks is near state-of-the-art level.
However, the model's weakly supervised training on large-scale noisy data means it may generate text that is not actually spoken in the audio input (hallucination). It also performs unevenly across languages, with lower accuracy on low-resource and low-discoverability languages. The model's sequence-to-sequence architecture makes it prone to generating repetitive text.
What can I use it for?
The whisper-medium.en model is primarily intended for use by AI researchers studying the robustness, generalization, capabilities, biases, and limitations of large language models. However, it may also be useful as an ASR solution for developers, especially for English speech recognition.
The model's transcription capabilities could potentially be used to improve accessibility tools. While the model cannot be used for real-time transcription out of the box, its speed and size suggest that others may be able to build applications on top of it that enable near-real-time speech recognition and translation.
There are also potential concerns around dual use, as the model's capabilities could enable more actors to build surveillance technologies or scale up existing efforts. The model may also have some ability to recognize specific individuals, which raises safety and privacy concerns.
Things to try
One interesting aspect of the whisper-medium.en model is its ability to perform speech translation in addition to transcription. You could experiment with using the model to translate audio from one language to another, or compare its performance on transcription versus translation tasks.
Another area to explore is the model's robustness to different types of audio input, such as recordings with background noise, accents, or technical terminology. You could also investigate how the model's performance varies across different languages and demographics.
Finally, you could look into fine-tuning the pre-trained whisper-medium.en model on a specific dataset or task, as described in the Fine-Tune Whisper with Transformers blog post. This could help improve the model's predictive capabilities for certain use cases.

The whisper-medium model is a pre-trained speech recognition and translation model developed by OpenAI. It is part of the Whisper family of models, which demonstrate a strong ability to generalize to many datasets and domains without the need for fine-tuning. The whisper-medium model has 769 million parameters and is trained on either English-only or multilingual data. It can be used for both speech recognition, where it transcribes audio in the same language, and speech translation, where it transcribes audio to a different language. The Whisper models are available in a range of sizes, from the whisper-tiny with 39 million parameters to the whisper-large and whisper-large-v2 with 1.55 billion parameters. Model inputs and outputs Inputs Audio samples in various formats and sampling rates Outputs Transcriptions of the input audio, either in the same language (speech recognition) or a different language (speech translation) Optionally, the model can also output timestamps for the transcribed text Capabilities The Whisper models demonstrate strong performance on a variety of speech recognition and translation tasks, including handling accents, background noise, and technical language. They can be used in zero-shot translation, taking audio in one language and translating it to English without any fine-tuning. However, the models can also sometimes generate text that is not actually present in the audio input (known as "hallucination"), and their performance can vary across different languages and accents. What can I use it for? The whisper-medium model and the other Whisper models can be useful for developers and researchers working on improving accessibility tools, such as closed captioning or subtitle generation. The models' speed and accuracy suggest they could be used to build near-real-time speech recognition and translation applications. However, users should be aware of the models' limitations, particularly around potential biases and disparate performance across languages and accents. Things to try One interesting aspect of the Whisper models is their ability to handle audio of up to arbitrary length through a chunking algorithm. This allows the models to be used for long-form transcription, where the audio is split into smaller segments and then reassembled. Users can experiment with this functionality to see how it performs on their specific use cases. Additionally, the Whisper models can be fine-tuned on smaller, domain-specific datasets to improve their performance in particular areas. The blog post on fine-tuning Whisper provides a step-by-step guide on how to do this.
