Her friend, despite excelling in coding and problem-solving, struggles with speaking English due to her accent and regional vowel shifts.\n\nDuring an automated AI assessment, her voice was flagged as \"unclear\" due to her accent, leading her to doubt her abilities and contemplate leaving corporate jobs. The author promised her friend a better solution, one that could provide empathetic guidance without leaving her laptop.\n\nThe \"Placement Pronunciation Coach\" is an acoustic-backed, locally-run AI speech evaluation dashboard designed specifically for students facing interview anxiety. It uses a hybrid acoustic pipeline that includes:\n\n1. Target Prompt Alignment: Compares expected interview responses against recorded user audio.\n2. Acoustic Ambiguity Detection: Uses OpenAI Whisper with word_timestamps=True to identify words where speech clarity drops (threshold at 0.75).\n3. Phonetic Sound Alignment: Converts expected and spoken text into IPA/Arpabet phonemes to detect real acoustic mismatches.\n4. Empathetic Coaching via Gemma 2:2b: Empathetic system prompts from Google Gemma 2 generate supportive communication scorecards, natural interview rewrites, and simple syllable sound-outs.\n\nThe tool runs entirely locally, ensuring privacy, offline accessibility, and customized empathy for the user.",
