Speechify’s AI Voice Research Lab Launches SIMBA 3.0 Voice Model to Power Next Generation of Voice AI

Speechify announced the early rollout of SIMBA 3.0, its latest proprietary voice AI model developed by the Speechify AI Research Lab, designed to power production-grade text-to-speech, speech recognition, and real-time speech-to-speech applications. Available to select third-party developers through the Speechify Voice API, SIMBA 3.0 delivers high voice quality, low latency, and cost-efficient scaling for AI agents, voice automation, accessibility, and content platforms. Full general availability is planned for March 2026.

Speechify’s Voice AI Research Lab Launches SIMBA 3.0 Voice Model to Power Next Generation of Voice AI

Speechify is announcing the early rollout of SIMBA 3.0, its latest generation of production voice AI models, now available to select third-party developers through the Speechify Voice API, with full general availability planned for March 2026. Built by the Speechify AI Research Lab, SIMBA 3.0 delivers high-quality text-to-speech, speech-to-text, and speech-to-speech capabilities that developers can integrate directly into their own products and platforms.

“SIMBA 3.0 was built for real production voice workloads, with a focus on humanlike quality, stability, low latency, and reliable performance at scale. Our goal is to give developers voice models that are easy to integrate and strong enough to support real world applications from day one,” said Raheel Kazi, Engineering Leader at Speechify.

Speechify is not a voice interface layered on top of other companies’ AI. It operates its own AI Research Lab dedicated to building proprietary voice models. These models are sold to third-party developers and companies through the Speechify API for integration into any application, from AI receptionists and customer support bots to content platforms and accessibility tools.

Speechify also uses these same models to power its own consumer products, while also providing developers access through the Speechify Voice API. This matters because the quality, latency, cost, and long-term direction of Speechify’s voice models are controlled by its own research team rather than by outside vendors.

Speechify’s voice models are purpose-built for production voice workloads and deliver best-in-class model quality at scale. Third-party developers access SIMBA 3.0 and Speechify voice models directly through the Speechify Voice API, with production REST endpoints, full API documentation, developer quickstart guides, and officially supported Python and TypeScript SDKs. The Speechify developer platform is designed for fast integration, production deployment, and scalable voice infrastructure, enabling teams to move from first API call to live voice features quickly.

This article explains what SIMBA 3.0 is, what the Speechify AI Research Lab builds, and why Speechify delivers top-tier voice AI model quality, low latency, and strong cost efficiency for production developer workloads, establishing it as the leading voice AI provider, outperforming other voice and multimodal AI providers such as OpenAI, Gemini, Anthropic, ElevenLabs, Cartesia, and Deepgram.
