Project Awarded 2023
Victoria: the first synthetic voice for sports news in Spanish
A pioneering project to create an AI-generated voice for PRISA Radio to read sports news, the first of its kind launched in Spain.
Applied AI lab: voice, conversation and multimodal agents
We bring the latest in voice and AI to conversations that work.
We build synthetic voices, AI assistants and agents that converse through voice and text, for media companies, brands and universities. Our specialty: Spanish, in all its variety.

Sound familiar?
Organizations come to us with challenges like these.
“Our agent answers, but it can't hold a conversation. It sounds like a machine, not like our brand.”
Conversational agents, designed and built
Through conversation design we shape its personality and dialogues, build it and test it with real users until it sounds natural and on-brand.
“We want a voice of our own, not the one everybody else uses.”
Custom synthetic voices
We build your custom brand voice with speech synthesis, in Spanish and its accents.
“We have a research project and don't know how to turn it into something usable, and sellable.”
Applied AI research and prototypes
We turn your research into a prototype people can test.
“We need to know our assistant is reliable before we launch it.”
Assistant and agent evaluation
We measure what your assistant understands, where it gets lost and when it shouldn't answer.
“Our team has to design an agent or a chatbot and nobody knows where to start.”
Tailored training
Workshops built around a case from your company, so your team leaves knowing where to start.
“Our content doesn't reach people who can't read it or don't speak the language.”
Fonos
With Fonos you turn text into audio, in your voice or your brand's, in your audience's language.
