+# Finetuned Verbatim model. 
+
+This model is trained 200 additional steps on top of the model below. This makes it outputting only text in lowercase and without punctation. It is also considerably more verbatim, and will not make any attempt at correcting grammatical errors in the text
+
+# NB-Whisper Large (Release Candidate)
+
+**IMPORTANT:** These models are currently Release Candidates. We are in the final stages of testing. If everything proceeds smoothly, we plan to officially release the models later this month.
+
+Introducing the **_Norwegian NB-Whisper Large model_**, proudly developed by the National Library of Norway. NB-Whisper is a cutting-edge series of models designed for automatic speech recognition (ASR) and speech translation. These models are based on the work of [OpenAI's Whisper](https://arxiv.org/abs/2212.04356). Each model in the series has been trained for 250,000 steps, utilizing a diverse dataset of 8 million samples. These samples consist of aligned audio clips, each 30 seconds long, culminating in a staggering 66,000 hours of speech. For an in-depth understanding of our training methodology and dataset composition, keep an eye out for our upcoming article.

+## Model Details
+
+The NB-Whisper series offers models in five distinct sizes: Tiny, Base, Small, Medium, and Large, each designed to cater to different requirements. These models are balanced for common use cases.
+
+
+| Model Size | Parameters | Model |
+|------------|------------|------------|
+| Tiny       | 39M        | [NB-Whisper Tiny](https://huggingface.co/NbAiLabBeta/nb-whisper-tiny) |
+| Base       | 74M        | [NB-Whisper Base](https://huggingface.co/NbAiLabBeta/nb-whisper-base) |
+| Small      | 244M       | [NB-Whisper Small](https://huggingface.co/NbAiLabBeta/nb-whisper-small) |
+| Medium     | 769M       | [NB-Whisper Medium](https://huggingface.co/NbAiLabBeta/nb-whisper-medium) |
+| Large      | 1550M      | [NB-Whisper Large](https://huggingface.co/NbAiLabBeta/nb-whisper-large) |
+
+Additionally, there are two variants available for each size:
+
+- **Verbatim version**: This lower-cased variant is more literal and suitable for tasks requiring detailed transcription, such as linguistic analysis.
+- **Semantic version**: This variant focuses less on verbatim accuracy but captures the essence of content, ideal for meeting minutes and subtitling.
+
+All models are used in the same manner. Here are the available models:
+
+| Model Size | Parameters | Verbatim version | Semantic version |
+|------------|------------|------------|------------------|
+| Tiny       | 39M        | [Tiny - verbatim](https://huggingface.co/NbAiLabBeta/nb-whisper-tiny-verbatim) | [Tiny - semantic](https://huggingface.co/NbAiLabBeta/nb-whisper-tiny-semantic) |
+| Base       | 74M        | [Base - verbatim](https://huggingface.co/NbAiLabBeta/nb-whisper-base-verbatim) | [Base - semantic](https://huggingface.co/NbAiLabBeta/nb-whisper-base-semantic) |
+| Small      | 244M       | [Small - verbatim](https://huggingface.co/NbAiLabBeta/nb-whisper-small-verbatim) | [Small - semantic](https://huggingface.co/NbAiLabBeta/nb-whisper-small-semantic) |
+| Medium     | 769M       | [Medium - verbatim](https://huggingface.co/NbAiLabBeta/nb-whisper-medium-verbatim) | [Medium - semantic](https://huggingface.co/NbAiLabBeta/nb-whisper-medium-semantic) |
+| Large      | 1550M      | [Large - verbatim](https://huggingface.co/NbAiLabBeta/nb-whisper-large-verbatim) | [Large - semantic](https://huggingface.co/NbAiLabBeta/nb-whisper-large-semantic) |

+
+## How to Use the Models
+
+### Online Demos
+You can try the models directly through the HuggingFace Inference API, accessible on the right side of this page. Be aware that initially, the model needs to load and will run on limited CPU capacity, which might be slow. To enhance your experience, we are temporarily hosting some models on TPUs for a few days, significantly boosting their performance. Explore these under the **Spaces** section on the [Main Page](https://huggingface.co/NbAiLabBeta/).
+
+### Local Setup with HuggingFace
+Alternatively, you can download the models for local usage. The Tiny, Base, and Small models are optimized for CPU execution. For the Medium and Large models, we recommend a system equipped with a GPU to ensure efficient processing. Setting up and using these models with HuggingFace's Transformers is straightforward, provided you have [Python](https://www.python.org/downloads/) installed on your machine. For practical demonstrations, refer to examples using this [sample mp3 file](https://github.com/NbAiLab/nb-whisper/raw/main/audio/king.mp3).
+
+```bash
+# Download the sample file
+> wget -N https://github.com/NbAiLab/nb-whisper/raw/main/audio/king.mp3
+
+# Install necessary libraries. 
+> pip install transformers>=4.35.2
+```
+
+After this is done, you should be able to run this in Python:
+
+```python
+from transformers import pipeline
+
+# Load the model
+asr = pipeline("automatic-speech-recognition", "NbAiLabBeta/nb-whisper-large-verbatim")
+
+#transcribe
+asr("king.mp3", generate_kwargs={'task': 'transcribe', 'language': 'no'})
+
+```
+
+<details>
+<summary>Expected output</summary>
+
+```json
+{
+  {'text': ' Nordmenn er nordlendinger, trøndere, sørlendinger og folk fra alle andre regioner. Nordmenn er også innvandret fra Afghanistan, Pakistan, Polen, Sverige, Somalia og Syria. Det er ikke alltid så lett å si hvor vi er fra, hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra.'}
+}
+```
+</details>
+
+Examining the output, we see that there are multiple repetitions in the end. This is because the default length is 30 seconds and the video is 1:25 minutes. By passing the ```chunk_lengt_s``` argument, we can transcribe longer file.
+
+```python
+asr("king.mp3", chunk_length_s=30, generate_kwargs={'task': 'transcribe', 'language': 'no'})
+```
+<details>
+<summary>Expected output</summary>
+
+```json
+{
+{'text': ' Nordmenn er nordlendinger, trøndere, sørlendinger og folk fra alle andre regioner. Nordmenn er også innvandret fra Afghanistan, Pakistan, Polen, Sverige, Somalia og Syria. Det er ikke alltid så lett å si hvor vi er fra, hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra. Hvilken nasjonalitet vi er fra, hvilken nasjonalitet vi tilhører. Det vi kaller hjem, er der hjertet vårt er, og det kan ikke alltid plasseres innenfor landegrenser.

Mitt største håp for Norge er at vi skal klare å ta vare på hverandre, at vi skal bygge dette landet videre på tillit, fellesskap og raushet.'}
+```
+</details>
+
+Here the output looks a lot better. We can also ask the model to output timestamps:
+```python
+asr("king.mp3", chunk_length_s=30, return_timestamps=True, generate_kwargs={'task': 'transcribe', 'language': 'no'})

+### Whisper CPP
+Whisper CPP is a C++ implementation of the Whisper model, offering the same functionalities with the added benefits of C++ efficiency and performance optimizations. This allows embedding any Whisper model into a binary file, facilitating the development of real applications. However, it requires some familiarity with compiling C++ programs. Their [homepage](https://github.com/ggerganov/whisper.cpp) provides examples of how to build applications, including real-time transcription. 
+
+We have converted this model to the ggml-format model used by Whisper CPP binaries. The file can be downloaded [here](blob/main/ggml-model.bin).
+
+### API
+Instructions for accessing the models via a simple API are included in the demos under Spaces. Note that these demos are temporary and will only be available for a few weeks.
+
+## Training Data
+The training data originates from Språkbanken and the National Library of Norway's digital collection, including:
+
+- NST Norwegian ASR Database (16 kHz) and its corresponding dataset
+- Transcribed speeches from the Norwegian Parliament by Språkbanken
+- TV broadcast (NRK) subtitles (NLN digital collection)
+- Audiobooks (NLN digital collection)
+
+## Downstream Use
+
+The models, especially the smaller ones, may exhibit occasional hallucinations and may drop parts of the transcript. They are designed to convert spoken language into grammatically correct written sentences, which might not always be word-for-word translations. We have made two extra model variant for users that want a different transcription style. We encourage users to try the models themselves to get a better understanding.
+
+## Bias, Risks, and Limitations
+
+Using these models without adequate risk assessment and mitigation could be considered irresponsible. They may contain biases or other undesirable distortions. Users who deploy these models or integrate them into systems or services are responsible for mitigating risks and complying with applicable AI regulations. The National Library of Norway, as the model owner, disclaims liability for any outcomes resulting from third-party use of these models.
+
+### Software
+The model was trained using Jax/Flax and converted to PyTorch, Tensorflow, whisper.cpp, and ONXX formats. These are available under `Files and versions`. We welcome requests for conversion to other formats. All training code and scripts are released under the Apache License 2.0 in the GitHub repository [nb-whisper](https://github.com/NbAiLab/nb-whisper/).
