Voctro Labs is a Barcelona-based AI voice technology company founded in 2011, built on 15+ years of research at UPF. Its Voctro Engine powers speech and singing synthesis, voice transformation, and audio time-scaling, with products including the Voiceful API/SDK for app developers and VOCALOID singers for musicians. It targets B2B clients in music, games, advertising, and film — not end consumers — making it a specialist licensing partner rather than a self-serve tool.
