Episode notes
LLMs + Studio TTS Power New Voice UX
- Modern LLM understanding plus high-fidelity TTS unlocks truly immersive voice experiences.
- Combining these advances makes voice interactions far more capable than 2017–2018 systems.
Discovery Sparked By Price And Quality
- Andrei recounts first spotting Inworld's TTS offering because it was high quality and 20x cheaper than competitors.
- That cost-quality moment prompted NLX to reach out and start the partnership conversation.

- Inworld targeted cost as a primary bottleneck and engineered TTS to hit a much lower price point.
- They keep provider-agnostic integrations but build components where customers need better cost-quality tradeoffs.
