Chat Without Barriers, Speak Any Language, and now on Telegram! VivaVoice is a messaging app with AI translation that understands more than words — it gets tone, gender, and formality right, so your messages sound like you in every language. Built-in text-to-speech makes it a powerful everyday tool and a lifeline for AAC users. REAL-TIME AI TRANSLATION Type in your language; they read in theirs — instantly. VivaVoice goes beyond word-for-word: it picks the right formality (tú or usted, du or Sie), keeps gendered grammar agreeing with the speaker, and preserves tone so slang stays casual and warmth doesn't get lost. INSTANT MESSAGING Everything you expect from a modern messenger — real-time delivery, read receipts, typing indicators, reactions, and photo and video sharing. TEXT-TO-SPEECH Hear any message spoken aloud in natural, high-quality voices across many languages. A great everyday feature — and essential for AAC users who speak through their device. AI COMPANIONS Chat with bots that have real personality — language tutors, study buddies, travel guides, and more — or build your own with its own voice, personality, and knowledge. PRIVATE & SECURE Chats where everyone shares a language are end-to-end encrypted — only your devices hold the keys — and every conversation is encrypted in transit and at rest. Download VivaVoice and start talking to anyone, in any language.
