About AltVoice
Built in Porto.
Made for your imagination.
We’re a young Portuguese startup building with voice and sound. From Porto, we bring together our own infrastructure, model development, and a creative platform shaped by the people who use it.
Curious people.
Something worth building.
A voice can bring a character to life. A sound can make an imagined place feel real. We started AltVoice because we want more people to have the freedom to make those moments.
We’re still growing, and the product grows with us. We listen to what people make, where they get stuck, and what they wish they could do next. That feedback helps us decide what to improve, from the way a voice sounds to the way a tool feels.
Our models & infrastructure
The space to build
our own way.
We have our own hardware and infrastructure, and we’re developing our own models. Running the technology ourselves gives us room to experiment, improve it, and bring that work into a product people can actually use.
We also use selected partner models when they offer better quality or a capability that fits the task. Our own research and outside innovation both have a place here. What matters is the experience you get.
Built, tested, and refined through real use.For model builders
Your model.
Room to grow.
Building a model and getting it into people’s hands are different challenges. If your team has a promising voice or audio model, we’re open to helping you take that next step.
We can explore hosting it on our hardware and bringing it to real users through AltVoice. You can learn how it performs beyond a demo, without first building your own serving infrastructure or a whole consumer product.
Let’s talk about the model, the experience you want to test, and what a useful collaboration would look like.
Tell us what you’re buildingOpen to what’s next
Good things start
with a conversation.
You don’t need to fit a particular kind of partnership to get in touch. We’re open to working with researchers, creators, product teams, and people with an idea we haven’t thought of yet.
Talk to us about model hosting, API access, an integration for your product, or a different way of working together. Tell us what you want to make possible, and we’ll explore what we can build together.
Already using AltVoice? We want to hear from you too. The things you love, the things that don’t quite work, and the ideas you send all help shape what comes next.
