distil-whisper-german

This model is a German Speech Recognition model based on the distil-whisper technique. The model weights count 756M parameters and with a size of 1.51GB in bfloat16 format.

As a follow-up to the Whisper large v3 german we decided to create a distilled version for a faster inference with minimal quality loss.

Intended uses & limitations

The model is intended to be used for German speech recognition tasks. It can be used as local transkription service or as a part of a larger pipeline for speech recognition tasks. While counting only half of the parameters of the large model, the quality is still very good and can be used for most tasks. The latency is low enough to be used in real-time applications when using optimization toolkits like tensorrt.

Dataset

The dataset used for training is a filtered subset of the Common Voice dataset, multilingual librispeech and some internal data. The data was filtered and double checked for quality and correctness. We did some normalization to the text data, especially for casing and punctuation.
