VoxTwin translates your voice in real time during video calls and plays back your message in a voice that sounds like you. Ideal for interviews, meetings, and international conversations, with an AI assistant that helps you as you speak.
Three steps, without interrupting your video call
Join your video call as usual. VoxTwin listens to your voice and the other participant's at the same time, without interrupting or modifying the call.
Your voice is translated to the other participant's language in under 500ms. The app learns the conversation context and improves accuracy as the session progresses.
The translation plays back with your own voice timbre through the video call. Your contact hears you in their language without perceiving that you're using a translator.
Built specifically for video calls on Windows
Translates your voice to the visitor's language and vice versa, simultaneously. Both participants understand each other naturally, without waiting or interruptions.
The translation doesn't sound like a generic computer voice — it sounds like you. The other participant doesn't perceive that you're using a translator.
An AI assistant monitors the conversation and suggests answers or context in your language while the call is happening. Ideal for interviews or technical meetings.
The longer the session, the better it understands the topic. VoxTwin remembers the terms used and maintains translation consistency from start to finish.
When you close the session, you automatically receive a conversation summary, key points discussed, and a bilingual glossary of the most relevant terms.
Configure the language pair, voice type, and preferences directly from the app interface. No config files or technical knowledge needed.
VoxTwin uses your own API keys from voice and AI providers — not ours. Here's why that's an advantage, not an inconvenience.
Your API keys are stored only on your computer. VoxTwin has no access to them, cannot read or leak them. If we close tomorrow, your credentials are still yours.
You pay directly to each provider (Deepgram, DeepL, ElevenLabs) with no middlemen or hidden markup. Most have free tiers sufficient for normal sessions.
Your keys work with any other application. You're not tied to VoxTwin — if you find something better in the future, you migrate in seconds without losing anything.
For normal use of 2–3 sessions per week of ~30 minutes, free tiers cover everything:
