Say & Solve: SYNAPSE — a futuristic brain-training and word puzzle experience combining vocabulary, speech, and cognitive challenges. Three dashboards: Lexicon Challenge (word puzzles): Word Scramble unscrambles vocabulary tiles across difficulty levels with hints and progress tracking. Crack the Code solves daily substitution ciphers to maintain streaks and earn XP. Voice Lab (speech training): Voice Articulation Trainer tests pronunciation by speaking target words aloud. Live Audio Spectrum shows a real-time voice waveform. Percentage Pronunciation Analysis gives accuracy scores, phonetic breakdowns, and audio playback. Cognitive Stim (brain training): Pattern Pulse tests spatial memory with matrix grid sequences. Logic Loop connects circuit nodes to complete energy flows before time runs out. A live HUD tracks score, timer, and levels completed. Persistent identity: Google Sign-In syncs XP, level, rank, streak, and badges across devices. Ranks progress from Apprentice to Master Mind. XP unlocks themes (Neon Red, Cyber Cyan, Matrix Green, Plasma Violet). Includes a vocabulary library with dictionary search, text-to-speech, and custom word pack imports. Other features: microphone-based speech recognition, daily quests and streaks, a global leaderboard, and offline PWA support.
