Case Study: Praktika.ai boosts AI tutor engagement and scales multilingual voice learning with ElevenLabs TTS

Praktika.ai upgrades AI tutors with ElevenLabs TTS

Praktika.ai, an AI language learning app, needed to scale its platform with high-quality, expressive text-to-speech (TTS) to power its generative AI tutors. Their challenge was to find a reliable TTS infrastructure that could support rapid global growth across multiple languages while maintaining consistent voice quality and emotional realism for an immersive user experience. They partnered with ElevenLabs to implement its Text to Speech service.

By implementing ElevenLabs' TTS, Praktika.ai gained access to human-like, emotionally expressive voices and seamless multilingual support. The solution was highly scalable, allowing Praktika to triple its monthly voice credit usage and expand from one to nine languages without performance issues. The results included a 15% increase in average user session length, improved user retention, and a viral social media campaign that helped propel the app into the top 10 global language learning rankings. ElevenLabs provided the critical voice technology that became a core part of Praktika's brand identity.
