The story
A conversational language learning platform teaches over 80 languages to more than 5 million users through real-time spoken practice.
The platform's voice-intensive nature made text-to-speech one of the largest infrastructure cost categories. Additionally, latency delays and generic voices broke the immersion required for effective conversational practice.
The company integrated Inworld TTS to power multilingual AI teachers, completing the deployment in less than one week. The system uses voice cloning to create distinct personas for role-play characters across various learning modes. A four-week A/B test validated the solution across both free and paid user segments before scaling.
Scope & timeline
- Integration in less than one week
- 7% increase in feature usage
