Privoca — Practice speaking for real life
Privoca is an on-device AI language practice app. Conversations, speech recognition, and scenario drills run locally on your iPhone—your recordings and chats are not uploaded to our servers. Built for learners who care about privacy.
Speak up. Get instant feedback.
• Talk or type—practice feels like chatting with a real tutor
• Owen, your on-device AI coach, teaches in your target language; ask questions in your native language anytime
• Offline speech recognition so you can listen, speak, and improve in one flow
50+ real-world scenarios, ready to go
Airport check-in, hotel stays, coffee orders, doctor visits, grocery checkout, job interviews, and more. Each scenario includes vocabulary warm-up and guided dialogue so phrases stick when you need them.
8 languages to learn
English, Chinese, Japanese, Korean, Spanish, French, German, and Russian—with a multilingual app interface.
AI-generated custom scenarios
Describe a situation you want to practice (e.g. “renting a bike in Tokyo”), and Privoca builds a tailored lesson on your device.
Why Privoca?
• On-device AI: core tutoring and ASR run locally—your data stays on your phone
• Scenario-based learning: speak in context, not isolated word lists
• Great for commutes, travel prep, and last-minute speaking practice
First-time setup
To keep the install size small, Gemma and WhisperKit models are downloaded inside the app on first launch (~3GB). Resume supported; users in China can use the ModelScope mirror. After download, practice works offline.
Privacy & data
Privoca does not operate backend servers to store your conversations. Your voice, text, and practice data stay on your device by default. The microphone is used only when you actively record. Model files are downloaded from third-party sources (e.g. Hugging Face, ModelScope) to your device for offline use.
