Inworld AI

#1 ranked TTS with under 200ms latency, voice cloning, and 25x lower cost. Realtime agents built for scale

Inworld AI provides realtime voice and language infrastructure for consumer-facing applications, from companion apps to games. It describes itself as a research lab and inference provider, offering first-party text-to-speech and speech-to-text models, the LLMs you choose, and the inference underneath, all through modular APIs.

The text-to-speech is pitched as top-ranked with under 200ms latency and voice cloning, and the company says customers cut voice and AI costs by 40% to 95% after moving over. Other pieces include a realtime API for speech-to-speech interaction, LLM routing that picks a model and tools per user and context, and dedicated GPUs. Target areas span social and companion apps, education, health and wellness, agentic workforces, and games and media, which is why the directory files it under Gaming with tags for characters, dialogue and NPCs.

Pricing is usage-based across plans, with a Growth plan and lower rates at enterprise scale. Compare the published rates against your current provider, then get started with the API.
