Lucas and Luna explore how mobile apps are using on-device AI to modulate voices in real time—changing pitch, tone, and accent during calls, recordings, and live streaming. They break down the technology behind voice conversion models that run entirely on the phone, preserving privacy while enabling new use cases from accessibility to entertainment. The episode focuses on the specific case of a 2025 startup called VoixAI that raised $12 million for a real-time voice modulation SDK, and how major messaging apps like Signal and Telegram are testing similar features. Lucas explains the latency challenges—how developers achieve sub-100-millisecond processing using neural audio codecs and transformer-based voice encoders—and Luna questions whether voice modulation could erode trust in phone calls. They also touch on regulatory implications, including the EU's proposed mandatory watermarking for AI-altered audio by 2027.
