Speechify launches SIMBA 3.0 for production-grade voice AI

TL;DR — Speechify released SIMBA 3.0 in March 2026, a proprietary voice model designed for production-grade TTS, speech recognition, and real-time speech-to-speech applications. The model is available to third-party developers through the Speechify Voice API.

What SIMBA 3.0 offers

SIMBA 3.0 is the latest version of Speechify’s internal voice AI model. It handles text-to-speech, automatic speech recognition, and real-time speech-to-speech conversion in a single architecture. Speechify positions it for AI agents, voice automation, accessibility tools, and content platforms.

The company claims improvements in voice quality, latency, and cost efficiency over SIMBA 2.0, though no public benchmarks or specific latency numbers have been published as of March 2026.

Why it matters

Speechify has historically focused on consumer-facing products (browser extensions, mobile apps for reading aloud). SIMBA 3.0 signals a shift toward the enterprise API market, where it will compete with ElevenLabs, Deepgram Aura, and Cartesia Sonic on developer mindshare.

The speech-to-speech capability is noteworthy. Real-time voice transformation without an intermediate text step reduces latency and preserves prosody, which matters for live translation and voice agent use cases.
