Yap is realtime AI voice translator for real conversations. It automatically detects the language being spoken and translates it into your native tongue in real time, with translated voice and live captions. Traditional translation apps make you choose a language, record a clip, wait for processing, then read or replay the result. Yap is built for the moment itself. Start a live session, choose your native language, and listen naturally. Yap detects foreign speech as it happens so you can understand what someone is saying while the conversation is still moving. Use Yap to understand people live: - Automatically detect the spoken language - Hear foreign speech translated into your native language - Read live captions when audio is hard to catch - Follow conversations at shops, restaurants, hotels, taxis, events, and meetings - Keep up without stopping the moment to type or replay clips Use Yap to speak back: - Talk in your own language and output translated speech - Communicate with people who do not speak your language - Ask questions, clarify details, and keep the exchange natural - Practice real phrases with spoken translation and captions Yap is useful for travel, international work, language learning, daily errands, family conversations, appointments, and any moment where typing into a translator slows everything down. Features: - Automatic spoken language detection - Real-time voice translation - Translated speech output - Live captions - Conversation history - Fast language switching - Phone and room microphone modes - Secure sign-in and account controls Supported target languages include Spanish, Portuguese, French, Japanese, Russian, Chinese, German, Korean, Hindi, Indonesian, Vietnamese, Italian, and English. Yap is designed for live spoken exchanges where timing matters. Open the app, pick your native language, tap to start, and understand foreign speech as it happens. AI translation may not always be perfect and should not be relied on as the only source for emergencies, medical advice, legal advice, or safety-critical communication. Download Yap and carry a live AI interpreter in your pocket.
