Silux Voice gives product and operations teams the building blocks for natural, multilingual voice conversations — without surrendering their data, their margins, or their roadmap to a closed cloud platform.
The voice market is dominated by closed APIs that meter every word. That model works for prototypes — it falls apart when a single contact-centre processes a million minutes a month, or when a regulated business needs guarantees that its caller audio never crossed an ocean.
We build the alternative. The same models, the same languages, the same low latency — with a price curve that doesn't punish you for growing.
Four principles that shape every decision — from the runtime up to the invoice.
Returning customers never have to repeat themselves. Silux Voice carries what it learned on the last call into the next one — with confidence scoring, provenance on every fact, and a single switch to turn it all off.
23 languages and 40+ voices out of the box, including dialects most cloud vendors charge a premium for. One stack, one bill, every customer in their own language.
Sub-second latency end-to-end so callers don't feel like they're talking to a robot — with barge-in, so they can interrupt mid-sentence exactly as they would with a person.
A clean HTTP API, code samples in cURL / JavaScript / Python, and integration recipes for Asterisk, FreeSWITCH, Twilio, Salesforce, HubSpot, and Zoho.
Founded after a year of running internal voice agents on rented per-minute APIs and watching the bill scale faster than the business.
Launched the managed platform with 40+ voices and 23 languages. First production deployments across customer support, appointment booking, and outbound sales.
Multi-account SaaS with per-customer voice profiles, full transcript pipeline, and CRM webhooks. Public API and developer docs released.
Silux Voice is part of the Silux group of British technology companies. Its closest sibling is Silux Call — a cloud business phone system, so you can take the number, the routing and the AI from one place instead of stitching three vendors together.
Local, national and toll-free numbers, or bring your existing number across with free porting.
IVR menus, hunt groups, time-of-day rules, transfers, voicemail-to-email and never-busy queues.
STIR/SHAKEN verification proves the number is genuinely yours, so outbound calls stop landing as "Spam Likely".
