Case Study: Pimsleur achieves 5x engagement with AE Studio's AI Spanish conversation practice

Pimsleur scales AI Spanish conversation practice to 175,000 learners with AE Studio

Pimsleur, a language learning company, needed to scale AI-powered Spanish conversation practice to its 175,000 existing learners. The challenge was to integrate this real-time, voice-based feature into their mobile platform while controlling costs associated with conversational AI and maintaining the high audio quality their brand is known for. AE Studio was engaged to build this solution.

AE Studio built a custom real-time voice processing pipeline using GPT-4o mini and ElevenLabs TTS to optimize costs without sacrificing quality. They implemented a personalized onboarding and a progressive feedback system. This solution resulted in 5x higher user engagement than projected, with 4,000 weekly active users at launch, all served by a cost-optimized architecture built to scale.
