From an idea to your team practising, in a day
Twinvoice is built to be simple. You set up a scenario, your people practise it out loud, and you see how they are doing. No code, no training, no waiting.
Four steps to your team practising
Upload your knowledge
Add the documents, notes, or scripts your team already works from. Twinvoice reads your content and understands the conversation you want people to practise.
Build the scenario
Give it a name, a personality, and a situation. Write the instructions in plain language, or let Twinvoice generate them from what you uploaded.
Choose your voice
Pick from professional stock voices in Dutch, English, German, French, and Spanish. Want something more personal? Upload 1 to 3 minutes of audio and Twinvoice creates a voice that sounds like you.
Invite your people
Share an invite link with your team. They open it, pick a scenario, and start practising out loud. No installation, no training session first.
Built for the conversations that matter
Your people practise cold calls, handle objections, and build confidence with AI prospects that behave like real decision-makers. Configure difficulty levels from friendly to skeptical, and let your own methodology do the teaching.
Your people practise giving constructive feedback, navigating difficult conversations, and developing personal leadership. The AI plays the colleague receiving feedback, then switches to coaching mode to review how it went.
Candidates and internal movers practise answering interview questions out loud with an AI recruiter that adapts to their CV, target role, and industry. Build speaking confidence that reading tips alone can never provide.
Organisations offer 24/7 emotional support through AI voice coaches trained in evidence-based methodologies. Emotion recognition, guided exercises, and crisis detection protocols keep users safe while providing accessible care.
New joiners practise company-specific scenarios before their first day. Product knowledge, customer interactions, internal processes. Consistent quality regardless of team size or location.
What is included
One platform for setting up scenarios, getting your people practising, and seeing how they are doing. No developers needed.
Scenario builder
Create practice scenarios with custom instructions, dynamic variables, and configurable personas. No coding required, and no limit on how many you build.
Voice cloning
Upload a short audio sample and get an AI voice that sounds like you. Powered by ElevenLabs instant voice cloning.
Knowledge base

Analytics and transcripts
Every session is analysed automatically. Review scores and transcripts, and see how skill is forming across your team, conversation by conversation.

“My sales students were terrified of cold calling. Now they practice with AI prospects until they're confident. I can hear the difference in their real calls within a week.”
Everything you need to know
Get clear answers to the questions we hear most so you can focus on what truly matters.
No. Twinvoice is designed for the people who run training, not developers. You write the instructions in plain language, upload your documents, and choose a voice. The platform handles the technical side. Most teams go from an idea to their people practising in a day.
You upload 1 to 3 minutes of clear audio of your voice. Twinvoice uses ElevenLabs instant voice cloning to create a digital version that sounds like you. The cloned voice is private, remains your property, and can be deleted at any time. You can also skip cloning and choose from professional stock voices in Dutch, English, German, French, and Spanish.
Twinvoice supports four types: roleplay (the AI plays a character like a prospect or interviewer), coaching (the AI guides people through exercises or reflection), hybrid (roleplay followed by feedback), and Q&A (answers based on uploaded documents). This covers everything from sales conversations and leadership development to interview preparation and wellbeing support.
You create a scenario, generate an invite link, and share it with your team. They open it, log in, pick a scenario, and start practising immediately. They need a device with a microphone and an internet connection. No app download required.
Twinvoice supports Dutch, English, German, French, and Spanish. You set the language per session, not per scenario, so one scenario can work across a team that speaks several languages.
