VOCTRO LABS SL

Their core work

Voctro Labs is a Barcelona-based music technology SME whose core expertise is the synthesis and modeling of the singing voice — building software capable of reproducing, transforming, and reviving vocal performances. Their REVIVOS project (2014) focused on digitally recreating deceased or unavailable singers through voice synthesis, indicating a commercially oriented product capability. By 2018, they were contributing their audio processing knowledge to TROMPA, a multi-country research project aimed at enriching online public-domain music archives. This positions them at the intersection of audio AI, digital musicology, and cultural heritage technology.

What they specialise in

How they've shifted over time

Voctro Labs entered H2020 with a tightly scoped commercial objective: synthesizing singing voices to revive performers, backed by an SME Instrument Phase 1 grant in 2014 — the smallest, most product-focused EU funding instrument. By 2018, they had joined TROMPA as a research partner in a larger RIA consortium, shifting their focus toward enriching public-domain music archives — a broader, more research-oriented application of their audio capabilities. The trajectory is clear: from a narrow voice synthesis product toward music technology research with cultural heritage and open-data dimensions.

Voctro Labs is moving from product-oriented voice synthesis toward collaborative music technology research, making them a credible specialist partner for projects combining audio AI, digital humanities, and cultural data infrastructure.

How they like to work

Voctro Labs has operated as both a project coordinator (REVIVOS, SME Instrument) and a specialist participant (TROMPA, RIA), demonstrating flexibility across project sizes and roles. Their 8 unique partners across 5 countries — drawn from just two projects — suggests active engagement in the European music technology community rather than a closed circle of repeat collaborators. In practice, they appear to be recruited for specific technical expertise in audio and voice processing, joining larger consortia as a focused contributor rather than a generalist anchor.

Voctro Labs has worked with 8 unique partners across 5 countries from only two projects, indicating genuine network breadth within European music technology and digital humanities research circles. No single partner dominates their history, suggesting openness to new consortium configurations.

What sets them apart

Voctro Labs occupies a rare niche in European R&D: a private SME with demonstrated technical depth in singing voice synthesis, applied to both commercial product development and academic research. Very few organisations combine the engineering precision required for voice modeling with the domain knowledge to contribute meaningfully to music information retrieval and cultural archive projects. For consortium builders in music AI, creative technology, or digital heritage, they offer a credible dual track record — independent project leadership and collaborative research participation.

Highlights from their portfolio

• REVIVOS
  As coordinator of an SME Instrument Phase 1 grant, REVIVOS marks Voctro Labs' commercial ambition — applying voice synthesis to revive real singers, a technically and ethically distinctive product direction.
• TROMPA
  Their largest project by budget (EUR 223,225) and scope, TROMPA placed Voctro Labs in a multi-country RIA consortium tackling online public-domain music archives, demonstrating their capacity to contribute to large-scale research collaborations.
