SpeechifyAI is a speech technology brand focused on expressive text-to-speech and voice cloning for developers and businesses. Its Simba model family turns written content into natural-sounding audio, with controls for delivery and emotion, and supports the creation of custom voice identities. The company provides access through a single API, alongside documentation, API references, quickstarts, and developer guidance for building speech-enabled products.

SpeechifyAI’s offerings are designed for applications such as reader apps, customer support, narration, and real-time voice experiences. Its streaming speech service is built for scalable use, and the company publishes dated measurements of Simba 3.2’s production time to first audio byte, independent voice-quality benchmark results, and modeled pricing comparisons. These figures are presented with methodology and limitations rather than as guarantees. Customers can explore voice samples, compare prepared recordings, review available plans, and begin building with a free API. SpeechifyAI also offers enterprise voice agents and custom deployments scoped with its team, serving organizations that need tailored speech solutions.
