A new meditation and sleep app called WhatsFeel utilizes AI to generate dynamic audio content in real-time, moving beyond static recordings. The app integrates LLM text generation with real-time TTS voice synthesis, adapting guidance based on user interactions and biometric signals like heart rate. To manage server bandwidth and latency, WhatsFeel employs a tiered caching strategy and a group sliding-window cache for non-biometric users, ensuring fresh content while reducing costs. AI
IMPACT This application demonstrates a novel use of LLMs and TTS for personalized, real-time audio experiences, potentially influencing future content generation tools.
