# DictErrorsDictation Error Analysis for Indic Languages
# SCRIBEDiagnostic Evaluation for Indic & Domain-Specific ASR

DictErrors is a specialized tool for analyzing ASR (Automatic Speech Recognition) transcription errors in Indic languages (Malayalam, Kannada). It provides fine-grained error metrics by categorizing tokens into base categories (WORD, NUMERAL, PUNCT) and optional domain-specific categories (LEGAL, MEDICAL, TECH, or custom).
`scribe-eval` is the open-source evaluation framework introduced in the SCRIBE
paper (*Diagnostic Evaluation and Rich Transcription Models for Indic ASR*,
under review at Interspeech 2026). It provides fine-grained error metrics for
ASR systems on Indic languages (Malayalam, Kannada, Hindi, ...) and on
domain-specific transcription (legal, medical, technical).

Domain-critical terminology is shielded from incorrect splitting and tracked separately — so a single misrecognized legal term doesn't inflate your general WER.
Token categories are decomposed into base classes (WORD, NUMERAL, PUNCT) and
optional domain classes (LEGAL, MEDICAL, TECH, or custom). Domain-critical
terminology is shielded from incorrect splitting and tracked separately — so a
single misrecognized legal term doesn't inflate your general WER.

## Installation

```bash
git clone https://github.com/adalat-ai-tech/dict-errors.git
cd dict-errors
uv sync && uv pip install -e .
pip install scribe-eval # core library
pip install 'scribe-eval[visualizer]' # adds Streamlit UI
pip install 'scribe-eval[charts]' # adds matplotlib charts
```

## Quick Start

```python
from dicterrors import text_error_rates, DomainConfig
from scribe import text_error_rates, DomainConfig

ref = "charged u/s 302 IPC on 22.05.2023"
hyp = "charged u/s 303 IPC on 22.05.2023"

File-based and custom inline configs are also supported. See [docs/domain-configuration.md](docs/domain-configuration.md).

## Examples

Runnable scripts under [`examples/`](examples/) demonstrate alignment,
single-sample reports, domain-config patterns, and full batch evaluation.
See [`examples/README.md`](examples/README.md) for the full index.

## Batch Processing

```bash
cd examples/
uv run batch_evaluate.py --input predictions.jsonl --domain-config config/legal_terms.txt --analysis --chart
uv run examples/batch_evaluate.py --analysis --chart
```

See [docs/batch-processing.md](docs/batch-processing.md) for the Python API, CLI arguments, and output schema.

## Interactive Visualizer

```bash
streamlit run visualizer.py
pip install 'scribe-eval[visualizer]'
scribe-visualizer
```

See [docs/visualizer.md](docs/visualizer.md).

## Dependencies

- `levenshtein>=0.27.1`, `jiwer>=4.0.0`, `streamlit>=1.53.0`, `tabulate>=0.9.0`
Core: `jiwer>=4.0.0`, `levenshtein>=0.27.1`, `tabulate>=0.9.0`

Optional extras: `matplotlib` (for `[charts]`), `streamlit` and `pandas` (for `[visualizer]`).

## Development

```bash
git clone https://github.com/adalat-ai-tech/scribe-eval.git
cd scribe-eval
uv sync --all-extras --dev # core + [charts] + [visualizer] + [dev]
```

### Running tests

```bash
uv run pytest # full suite
uv run pytest tests/test_analysis.py # one file
uv run pytest -k sandhi # name pattern (-k matches by substring)
uv run pytest -v # verbose, with each test name
uv run pytest --cov=scribe # with coverage
```

Tests are organised one file per library module under [`tests/`](tests/), plus
[`tests/test_paper_cases.py`](tests/test_paper_cases.py) for end-to-end golden
cases from the SCRIBE paper. `pytest` itself ships with the `[dev]` extra, so
`uv sync --all-extras --dev` (above) is required first.

### Lint and format

```bash
uv run ruff check src tests examples # lint
uv run ruff format src tests examples # auto-format
```

See [`docs/architecture.md`](docs/architecture.md) for the module map and a
glossary of project-specific terminology (sandhi, combined denominator, TER,
Accuracy, ...).

The SCRIBE paper is currently under anonymous review at Interspeech 2026. A
BibTeX entry will be added here once the proceedings or arXiv preprint are
