General-purpose Latvian ASR model
This is a fine-tuned whisper-large-v3 model for Latvian, trained by AiLab.lv using two general-purpose speech datasets: the Latvian part of Common Voice 17.0, and a Latvian broadcast dataset LATE-Media.
We also provide 4-bit, 5-bit and 8-bit quantized versions of the model in the GGML format for the use with whisper.cpp, as well as an 8-bit quantized version for the use with CTranslate2.
NB! This model is superseded by a newer version: whisper-large-v3-lv-late-cv19
Training
Fine-tuning was done using the Hugging Face Transformers library with a modified seq2seq script.
| Training data | Hours |
|---|---|
| Latvian Common Voice 17.0 train set (the V1 split) | 167 |
| LATE-Media 1.0 train set | 42 |
