Vext is a premier systems engineering house based in Casablanca, Morocco. We build AI products and own the hard parts ourselves: low-level DSP in C/Rust, sub-280ms Moroccan Darija telephony voice agents, ERP integrations (SAP, Sage), and 100% sovereign Moroccan infrastructure.

How does Vext Voice handle Moroccan Darija without hallucinating?

Vext Voice uses acoustic models fine-tuned on 1,400+ hours of multi-region Moroccan Darija with code-switching support for French and Classical Arabic. State transitions are governed by deterministic finite-state machines (FSM) linked directly to database transactions, preventing hallucinations.

Can Moroccan enterprises get up to 80% Tatwir Digital subsidies to work with Vext?

Yes. Vext is an accredited technical consultancy under Maroc PME programs. The Tatwir Digital framework co-finances up to 80% of eligible systems engineering, digital transformation, and cybersecurity projects up to 1,000,000 MAD.

Is Vext compliant with Moroccan CNDP Law 09-08 and data sovereignty?

Yes. All model inference, telephony recording, customer data, and database storage reside exclusively within sovereign Moroccan data center nodes in strict compliance with CNDP Law 09-08.

EVS Codec SIMD Acceleration for Telecom Networks

The Production Challenge & Problem

Why Standard Cloud Stacks and Legacy Tools Failed

Telecommunication media gateways handle millions of audio frames every minute. Standard software implementations of the 3GPP EVS codec saturated rack servers with heavy floating-point operations, creating CPU bottlenecks and requiring costly hardware expansions.

The Vext Sovereign Engineering Architecture

Custom Low-Latency Architecture & In-Country Execution

Vext re-engineered the mathematical DSP pipeline directly into vectorized SIMD instructions in C99 and Rust, allowing a single dual-socket rack server to handle 4,800 simultaneous HD audio calls with deterministic <12ms frame latency.

Architectural Context & Deployment Narrative

Telecommunication gateways handle millions of audio frames every minute. Traditional software implementations of the 3GPP EVS codec saturated rack servers with heavy floating-point operations. Vext re-engineered the mathematical DSP pipeline directly into vectorized SIMD instructions. The resulting engine processes 4,800 simultaneous HD audio streams on a single dual-socket server while strictly adhering to ITU-T and 3GPP bit-exact conformance specs.
