Docstrings generation was requested by @chcavignx. * #2 (comment) The following files were modified: * `scripts/models/audio/fast_whisper_objects.py` * `scripts/models/audio/load_all.py` * `scripts/models/audio/load_huggingface_objects.py` * `scripts/models/audio/models_check.py` * `scripts/models/audio/whisper_objects.py` * `src/audio/voice_agent_offline.py`

Refactored the main function to iterate through model loading phases with try/except blocks, ensuring that a failure in one phase does not prevent subsequent phases from running. Added a summary at the end to report successful and failed phases, and exit with a non-zero status if any phase fails.

…, Merge pull request #3 from chcavignx/coderabbitai/docstrings/45338c2 📝 Add docstrings to `test` Refactor model loading and config paths for repository-relative setup

Expanded and clarified docstrings for functions and modules in audio model management scripts, including Piper TTS example, Whisper, Fast Whisper, Hugging Face, and Vosk model utilities. The changes provide more detailed descriptions of function behavior, parameters, and return values to improve code readability and maintainability. Minor formatting and comment adjustments were also made.

📝 Walkthrough

Walkthrough

This PR modernizes audio model loading by introducing phase-based orchestration with error resilience, enhancing platform-aware model selection, improving download capabilities with resumption support, and expanding documentation across multiple audio module files. Key changes include a new phase-based execution framework in load_all.py with graceful failure handling and comprehensive docstring improvements describing download behavior, cache management, and platform-specific model selection.

Changes

Cohort / File(s)	Summary
Documentation enhancements (docstring-only updates) `scripts/models/audio/models_check.py`, `scripts/models/audio/load_huggingface_objects.py`, `src/audio/voice_agent_offline.py`	Expanded docstrings to clarify function behavior: model_exists now documents substring matching and symlink handling; load_huggingface_objects.run describes cache skip logic and error handling; voice_agent_offline._validate_piper_model documents FileNotFoundError for invalid paths. No functional changes.
Variable naming consistency `examples/TTS/text2speech_piper.py`	Renamed in-file text constants from TEXT_FR/TEXT_EN to text_fr/text_en for Python style consistency. Updated corresponding function calls to use new variable names.
Download and model selection enhancements `scripts/models/audio/fast_whisper_objects.py`, `scripts/models/audio/whisper_objects.py`	Enhanced download capabilities: added skip logic for cached models, actual snapshot_download calls with progress reporting, and HTTP resumption with Range headers. Implemented platform-aware model selection (base-only on Raspberry Pi, base+extended elsewhere). Expanded docstrings to document download workflows and fallback behavior.
Phase-based orchestration and error handling `scripts/models/audio/load_all.py`	Introduced phase-based execution framework replacing hard-coded sequential calls with dynamic phase enumeration. Added try/except wrapper for each phase to continue despite failures, with detailed error logging and traceback capture. Replaced static success message with summary report showing successful phase count and listing failed phases. Exit code 1 on any phase failure.

Poem

🐰 A Rabbit's Song of Models

Phase by phase, we hop along,
Download files both short and long,
Skip what's cached, resume with care,
Platform-wise, a model pair.
Error caught, we still go on,
Till all the audio tasks are done! 🎵

41-44: GPT-2 URLs point to GitHub tree view, not raw files.

The URLs use github.com/.../tree/master/... paths which serve HTML pages, not raw file content. Downloads will fail or return HTML instead of the expected vocab.bpe and encoder.json files.
Proposed fix - use raw content URLs
 GPT2 = [

🧹 Nitpick comments (1)

examples/TTS/text2speech_piper.py (1)
27-29: Parameter counter is immediately shadowed and never used.

The counter=1 parameter on line 27 is overwritten on line 29, making the parameter effectively useless. This appears to be pre-existing but worth fixing.
Proposed fix
-def setup_output_filename(base_path, base_name, suffix, counter=1):
+def setup_output_filename(base_path, base_name, suffix):
     """Generates a unique filename by appending a counter if needed."""
     counter = 1
Note: The same issue exists in examples/TTS/text2speech_espeak.py at the same line range per the relevant code snippets.
