# Whisper 3 Large Evaluation on Mozilla Common Voice 17 Rare Languages (Enhanced Metrics)

## Dataset Description

This enhanced dataset contains comprehensive evaluation results of OpenAI's Whisper 3 Large model on rare languages from Mozilla Common Voice 17, with extensive additional metrics for thorough ASR evaluation.

### Key Features

**Enhanced Error Metrics:**
- **WER** (Word Error Rate): Standard word-level error measurement
- **CER** (Character Error Rate): Character-level error measurement
- **MER** (Match Error Rate): Alternative error rate calculation
- **WIL** (Word Information Lost): Information loss measurement

**Edit Distance Analysis:**
- Word-level and character-level edit distances
- Normalized edit distance metrics
- Comprehensive distance analysis

**Length and Structure Metrics:**
- Word, character, and sentence counts
- Length ratios and differences
- Average word length analysis
- Sentence structure preservation

**Script-Specific Analysis:**
- Latin, Cyrillic, Armenian, Georgian, Tamil, Bengali character ratios
- Punctuation preservation analysis
- Script-specific performance metrics

**Statistical Metrics:**
- Jaccard similarity for vocabulary overlap
- Frequency correlation analysis
- Vocabulary union and overlap metrics
- Unique word analysis

### Dataset Statistics

- **Total samples**: 111,507
- **Languages**: 21 rare languages
- **Total metrics**: 56 comprehensive evaluation metrics
- **Scripts covered**: Latin, Cyrillic, Armenian, Georgian, Tamil, Bengali
