Praktika scales immersive language learning with ElevenLabs

Praktika helps people around the world learn new languages through realistic conversations with generative AI avatars. Each premium avatar is powered by ElevenLabs’ Text to Speech technology, bringing human-like voice emotion and clarity to every tutoring session.

Scaling from Startup to Global Platform

Since partnering with ElevenLabs in early 2024, Praktika has scaled the monthly voice credits usage three-fold, with peaks of 5x in several high volume months, reflecting rapid global adoption and product growth. As user volume grew, ElevenLabs’ TTS infrastructure made it seamless to scale while keeping quality consistent - something that became critical as Praktika expanded from one to nine languages and millions of learners.

“We’ve scaled in voice usage without ever hitting a performance ceiling,” said Adam Turaev, CEO of Praktika.ai. “That reliability is rare in generative AI infrastructure. ElevenLabs has been one of those partners we never had to worry about.”

Elevenlabs also provided Praktika with out-of-the-box code switching and multilingual support, which unlocked opportunities for Praktika to add more study languages and breakthrough vital functions like studying in the native language of the user, making the app more available for beginners.

TEXT TO SPEECH

Elevating the Learning Experience

Learners consistently mention the natural voices as one of the most engaging parts of the experience. Users often describe their avatar as “very realistic” and “engaging” according to data monitored over the last several months. Internal data shows that users exposed to ElevenLabs-powered voices stay longer and engage more deeply with their AI tutors.

• +15% increase in average session length right after voice upgrade in 2024
• A large number of users report that voices “feel more human and expressive” compared to alternatives

When Praktika ran A/B tests using other TTS models, metrics dropped noticeably - reinforcing that realistic emotional inflection is not just a nice-to-have, but a real performance driver especially for an avatar-based experience.

Voices that Drive Retention and Virality

When Praktika launched its “upgraded voices” campaign across social media, videos demonstrating the AI tutors’ expressiveness went viral, helping push the app into the top 10 global language learning apps by user ranking.

“The voices became part of our brand identity,” added Turaev. “Students immediately notice the difference when they move to our premium subscription. It’s not just better sound, it’s a more human connection.”

A Partnership Built for the Long Term

As Praktika continues expanding into new languages and learning modes, ElevenLabs remains a core part of its stack - one that supports growth without compromising on quality or emotional realism.
