Comprehensive Voice Processing Tests - ADDER+ Protocol Coverage Expansion
==========================================================================
Voice processing modules are critical business logic requiring comprehensive coverage.
This module targets 0% coverage voice modules for maximum impact toward 95% threshold.
Modules Covered:
- src/voice/speech_recognizer.py (286 lines, 0% coverage)
- src/voice/voice_feedback.py (308 lines, 0% coverage)
- src/voice/command_dispatcher.py (338 lines, 0% coverage)
- src/voice/intent_processor.py (235 lines, 0% coverage)
Test Strategy: Functional validation + property-based testing + integration scenarios
Coverage Target: Maximum coverage gain for 95% ADDER+ requirement
