Open Source Contributions
Speech Recognition & AI Models
Since 2021, Florian has worked on German automatic speech recognition (ASR) models:
- aware-ai/wav2vec2-large-xlsr-53-german-with-lm - German ASR model
- aware-ai/wav2vec2-xls-r-1b-5gram-german - Large-scale German ASR
- primeline/whisper-large-v3-turbo-german - Fast German transcription
- primeline/whisper-large-v3-german - High-quality German ASR
- primeline/whisper-tiny-german-1224 - German Whisper Tiny fine-tune; its model card reports 6.26% aggregate WER versus 5.49% for Whisper Medium on the listed evaluation sets
Notable Achievements
- 2020 model upload: aware-ai/bart-squadv2 has commits dating to June 2020.
- Research comparison: TEVR (2022), Table 6 reproduces and compares a German ASR result attributed to Zimmermeister (2022).
- Lorax work: Florian lists work on the Lorax inference server from November 2023 to June 2024 on his GitHub profile.
