Praktika.ai, a language learning platform, utilizes generative AI avatars powered by ElevenLabs' text-to-speech (TTS) technology to provide immersive and realistic language education. Since partnering with ElevenLabs in 2024, Praktika has expanded its offerings from one to nine languages and seen a threefold increase in monthly voice credits usage. The integration of ElevenLabs' TTS has allowed Praktika to maintain high-quality and emotionally expressive voices, which users find engaging and realistic, leading to increased session lengths and deeper engagement. This partnership has played a significant role in Praktika's global adoption and growth, with the expressive voices becoming a key component of the brand's identity. The TTS system's reliability and multilingual support have enabled Praktika to expand its user base and enhance the learning experience, with the platform now ranking among the top global language learning apps. As Praktika continues to grow, ElevenLabs' TTS remains an essential part of its infrastructure, supporting further expansion without sacrificing quality.
