Voice startup Freya released Adam and Eve, TTS voices it calls the most human-like ever built. Adam ranks #1 on Design Arena's Audio Realism Bench with an Elo of 1419 vs 1462 for real human speech in blind listening tests, well ahead of Cartesia Sonic 3.6 (1306), Eleven v3 Conversational (1202), Grok TTS (1150), Google Gemini 2.5 Pro TTS (1101) and OpenAI GPT Realtime 2 (1071). The team claims the uncanny valley has been crossed. API access opens in batches; they also open-sourced FreyaTTS-small, a from-scratch Turkish TTS model (48kHz, Apache 2.0) with paper, code and eval dataset.
