About VocalLab
VocalLab is an AI voice generation platform built for creators, educators, developers, agencies and businesses that need high-quality voiceovers without complex production workflows. The goal is straightforward: make professional voice generation accessible, predictable and useful for real creative and commercial work.
When and why it started
VocalLab launched in November 2025. It was created to fix a real frustration: good AI voices existed, but getting to them meant enterprise pricing, unclear commercial rights, or unreliable tools. VocalLab was built to be fast, honest about its limits, clear about commercial use, and reliable enough for both solo creators and business teams. Most users discover VocalLab through Google search — today that is over 1,000 new visitors every day, and growing fast.
Who runs VocalLab
VocalLab was created by Petr Sibirtsev, an independent software developer based in Israel. He is the founder of VocalLab and leads its development — he writes the code, talks to customers, and decides what ships next.

VocalLab is an actively maintained product with real users, paid customers, API infrastructure and an expanding voice platform — not a short-term experiment or a repackaged template.
VocalLab for business (B2B)
In addition to the creator product, VocalLab offers a B2B service: dedicated servers with pay-as-you-go pricing for companies that generate voice at scale, with predictable throughput and no shared queue. VocalLab already serves B2B customers in production and can take on more — contact support for details.
