OneVoice turns conversations between people who speak different languages into natural, everyday communication.

With OneVoice, text chats, voice calls and video calls can be translated in real time across 23 languages. During a conversation, the original speech and its translation are displayed side by side as live captions, while optional AI-generated voice playback allows the other person to hear what you are saying directly in their own language instead of having to read the translation.

The goal is simple: rather than stopping, translating, copying text or switching between different apps, both people can continue speaking normally in their preferred language while OneVoice handles the translation in the background.

One of OneVoice's most distinctive features is Guest Links. The person you want to call does not need to install OneVoice, create an account, subscribe to a service or purchase translation credits. You simply generate a link and send it to them. They open it in a standard web browser and join the translated voice or video call immediately.

Translation credits are charged entirely to the OneVoice user who creates the invitation. This makes the service especially useful when communicating with people who would never install a dedicated translation app just for a single conversation: international customers, suppliers, business partners, landlords, hotel or property owners, relatives living abroad, patients, travellers, technical support customers and many others.

It also removes one of the biggest practical barriers of traditional translated calling solutions: both participants do not need to use the same app.

OneVoice is fully cross-platform, with support for iPhone, Android and the web. A conversation can therefore start from a smartphone while the other participant joins from another phone, tablet or computer through their browser.

Beyond translated calls, OneVoice includes several additional tools:

• Real-time translated text chat, allowing people to exchange messages while writing in their own languages.

• Universal Translator, a built-in translator for quickly translating text between supported languages, with text-to-speech so translations can also be spoken aloud.

• AI call summaries, which can automatically generate a summary of a conversation in the language selected by the user.

• OneVoice Web, which connects to the mobile app through a QR code and allows conversations and OneVoice features to be used conveniently from a desktop or laptop computer.

• Live bilingual captions, showing both the original sentence and its translation to help users understand exactly what was said.

• Synthetic translated voice, allowing translated speech to be heard naturally during supported conversations rather than relying exclusively on subtitles.

Because the translation layer is handled by OneVoice, it can be used for both personal and professional communication: international business calls, customer support, remote meetings, travel, hospitality, healthcare communication, conversations with friends and relatives abroad, and many other situations where language would otherwise become a barrier.

Text chat is free to use. Translation of messages, translated voice features and live translated voice/video calls are premium services available through subscriptions or translation credit packs.

OneVoice is available across Android, iPhone and the web, making real-time multilingual communication accessible even when the person on the other side has never used OneVoice before.
