Realtime TTS 1.5 is #1 on Artificial Analysis, voted best in blind tests by thousands of real users. TTS-2 builds on that with six major upgrades: natural language voice direction for tone, emotion, speed, and pitch. Text-based voice design, where you describe a voice in words and generate it. Cross-lingual synthesis across 100+ languages preserving speaker identity. IPA phonetic control for brand names and rare words. And improved alphanumeric pronunciation. Try it free at inworld.ai/tts.
So I tried it, Speech to Speech. It confuses itself and hallucinates very quickly with just basic questions and conversation, I asked both bots how are you, what are you doing today, and what are you doing for dinner. Both gave me completely different spectrum of answers. They gave alot of filler responses like hey, hmm, huh, which I can understand why those are there. But Jason started telling me how to increase the gain of my television set, and Sarah thought I was going to a party. Also the vocal fidelity is alot to desire, in speech to speech. Just my honest feedback so far. Keep at it.
