Vapi and Speechmatics: Build agents that understand every voice

Speechmatics is now natively available on Vapi, the developer platform for building production-ready voice AI agents. 

With Vapi, you can orchestrate everything your agent needs through its easy-to-use visual interface, or drop into developer tools and a command-line interface when you want more control. 

Pair that orchestration with Speechmatics’ industry-leading speech recognition and your agents gain the strongest possible input layer, the ears they rely on to make sense of the world.

Why builders choose Speechmatics on Vapi

Voice agents that work in the wild rely on three main components: precision in noise, languages that scale with you, and domain & contextual awareness.

Here is how we deliver each.

Precision built for the real world

Accents, fast talkers, background noise. Real conversations are messy. Most ASR systems shine on clean lab audio, then fall short when deployed. 

Speechmatics is different. Our models are engineered for robustness in everyday conditions, delivering transcripts you can trust, no matter the environment, use case, or language. 

With Speechmatics as the transcriber inside Vapi, your agents gain a real-time input layer that is accurate, low latency, and built to handle the messy reality of human conversations. 

From accents and fast talkers to background noise, Speechmatics ensures your agents do not just hear, they truly understand.

Languages that scale with you

Voice AI cannot scale on English alone.

The real growth lies in markets across Asia, the Middle East, Europe, and Latin America, where most systems still struggle. 

Limited labeled training data means other ASR providers mishear accents, skip words, or fail entirely. 

Speechmatics has solved this differently by developing high-quality language models even in low-resource conditions. It is all part of our mission to understand every voice. 

Today, we deliver consistently high accuracy across 55+ languages, setting the benchmark for truly global voice AI.
