Creates log-mel spectrogram template for 'hey salty' wake word detection using synthetic speech generation. Template generated from 5 synthetic audio samples with varying pitch to improve robustness. - generate_wake_word_template.py: Script to synthesize and generate template - hey_salty.npy: 40-band log-mel template (40, 61) shape - wake_word_params.yaml: Updated template_path - README.md: Documentation for template usage and retraining procedures The template is used by wake_word_node.py via cosine similarity matching against incoming audio. Configurable sensitivity via match_threshold. Future work: Collect real training recordings to improve accuracy.
