daniel_whisper_finetune_base_v2

This model is a fine-tuned version of openai/whisper-base on an unknown dataset. It achieves the following results on the evaluation set:

• Loss: 0.3315

Model description

This is a personal fine-tune of the Whisper base model, trained on approximately 1 hour of audio featuring Daniel Rosehill's voice. The training data includes domain-specific vocabulary focused on:

• Technology and software development terminology
• A few Hebrew words and phrases

This model was created as a proof of concept for fine-tuning Whisper models for personal use and improved transcription accuracy on domain-specific content.

Training Infrastructure

Fine-tuning was performed using Modal GPU inference infrastructure.

Converted Formats

In addition to the standard SafeTensors format, this repository includes converted model formats in the converted/ directory:

• GGML format (converted/ggml/): For use with whisper.cpp

  • Cross-platform inference (desktop, mobile, edge devices)
  • Optimized for CPU and CUDA (NVIDIA GPU) acceleration
  • Compatible with iOS, Android, Raspberry Pi, and other platforms

• CTranslate2 format (converted/ctranslate2/): For use with faster-whisper

  • Highly optimized inference engine (4x faster than OpenAI Whisper)
  • Excellent CPU and GPU (CUDA) support
  • Lower memory usage with 8-bit and 16-bit quantization

Intended uses & limitations

This model is optimized for:

• Transcribing Daniel Rosehill's voice
• Technical and software development content
• Mixed English with occasional Hebrew terms

Limitations:

• Performance may degrade on voices significantly different from the training data
• Limited to the vocabulary and accent patterns in the training set
• Best suited for personal use rather than general-purpose transcription

Training and evaluation data

Training dataset consisted of approximately 1 hour of recorded audio featuring:

• Technical discussions and software development content
• Mixed English with occasional Hebrew vocabulary
• Single speaker (Daniel Rosehill)
