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 19.0, and the latest version of the Latvian broadcast dataset LATE-Media.

This version of the model supersedes the previous whisper-large-v3-lv-late-cv17 model.

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.

Training

Fine-tuning was done using the Hugging Face Transformers library with a modified seq2seq script.
