Teams building voice and speech apps often run into the same challenge when serving users around the world: every market has its own rules for data handling. Some require audio to stay within national borders; others mandate strict access controls, audit trails, or full residency. And for real-time use cases, latency and performance can vary widely depending on where processing takes place.
Introducing Soniox Sovereign Cloud. Starting today, Soniox is giving teams a simple, consistent way to meet these requirements without changing how they build. Soniox now runs locally in regions around the world, so that audio, transcripts, and logs can stay within their jurisdiction and operations stay aligned with local laws. Whether you’re building healthcare transcription in Japan, live voice agents in United States, or multilingual customer support in Poland, Soniox delivers consistent accuracy, low latency, and regional compliance.
The before times: slow, fragmented processes
With other providers, teams often needed to stitch together a mix of regional endpoints, compensating for uneven model quality, slower processing across borders, and compliance workflows that varied by market. Operating in three countries, for example, often meant maintaining three different setups. Soniox Sovereign Cloud removes that complexity entirely.
"Soniox allows DeliverHealth to scale InstaNote globally without compromising data sovereignty. We can deploy secure, region-isolated environments instantly, ensuring patient data never leaves its jurisdiction, saving us weeks of engineering overhead."
Built to run locally in any region
Sovereign Cloud is built on portable, region-ready architecture. Soniox can deploy on any compliant cloud infrastructure with GPU resources, from public clouds to regional and sovereign cloud providers. Each region runs as a fully self-contained environment.
- Local processing: All audio, transcripts, logs, and intermediate data are processed inside the selected region
- Local storage: Data does not cross borders. Storage, logs, and operational data remain within the jurisdiction.
- Consistent model in every region: The same native-speaker accuracy, 60+ language fluency, and real-time behavior; no “lighter” regional versions.
This architecture enables Soniox to meet regional requirements without fragmenting the developer experience or impacting performance.
Highly performant – and portable
In addition to automatic regional compliance, Soniox Sovereign Cloud guarantees that teams have access to the same fast, fluent, and accurate speech AI wherever they deploy.
- Local, low-latency performance
Running Soniox close to users significantly reduces round-trip delays. Real-time agents, captioning, and live translation feel more natural when processing happens within the region. This difference becomes even more meaningful as products expand into markets with strict data requirements or distributed user bases.
"Our voice agent finally feels instant everywhere. Latency dropped right away, and we didn’t have to change any code. By running on an EU deployment, we now fully meet all data-security requirements."
- Consistency across geographies
Each Sovereign Cloud region uses the same Soniox model with the same accuracy and the same streaming behavior. Teams don’t need separate rules for how workloads behave in different environments. This is especially important for products that operate across markets but need their interactions to be predictable anywhere, such as: customer support, education, compliance-driven communications.
"Before Soniox, our international users always had a noticeably different experience. Now accuracy and responsiveness match across all regions…it feels like one system instead of five."
- Portable infrastructure for expanding markets
Because Sovereign Cloud can run on any compliant cloud with GPU resources, adding new regions is straightforward. Teams can access new markets without designing separate infrastructures or negotiating bespoke deployments. This works great for regulated industries, multi-country operations, and organizations navigating national privacy laws.
"Having Soniox deployed directly in Japan is a game changer. The latency dropped instantly, and for the first time we can run real-time English and Japanese translation without any delays."
Available globally and ready for new regions
Soniox Sovereign Cloud is available today in the United States, European Union, and Japan. Coming soon to Korea, Australia, India, Canada, Saudi Arabia, UK, and Brazil. We can also deploy to additional regions based on customer needs.
For products that operate across borders or in regulated sectors, Sovereign Cloud provides a consistent, local-first way to deliver real-time speech AI with full regional control.
