Training History
This is the third round of fine-tuning Whisper Base for German ASR:
Table with columns: Round, Base Model, Dataset, Steps, WER| Round | Base Model | Dataset | Steps | WER |
|---|
| v1 | openai/whisper-base | flozi00/common_voice_19_0_de-labeled | 4,000 | ~15.6% |
| v2 | basha3la2/whisper-base-de | flozi00/asr-german-mixed | 15,000 | 14.16% |
| v3 | basha3la2/whisper-base-de-v2 | flozi00/asr-german-mixed | ~10,000 | 13.05% |
Training Note
Training for v3 was planned for 30,000 steps but was interrupted at approximately step 10,000 due to Kaggle's 12-hour session limit. The last checkpoint was saved and pushed to the Hub. Further training continues in v4.
