Universal-3.5 Pro Realtime is now available in Vapi
Blog post from AssemblyAI
AssemblyAI’s Universal-3.5 Pro Realtime speech-to-text model is now available as a selectable transcriber in Vapi’s dashboard, allowing voice-agent developers to enable it without a custom integration or separate contract. The model supports 18 languages, mid-sentence code-switching, up to 100 boosted custom keyterms, agent-context input, configurable prompting, language-code biasing, and selectable latency-versus-accuracy modes. AssemblyAI reports that it achieved a 1.22% pooled word error rate on Pipecat’s benchmark of real agent conversations, outperforming cited alternatives, while agent context reduced error rates by 10.2% in a separate 20,000-file benchmark. Users can activate the model by choosing AssemblyAI and Universal 3.5 Pro in an assistant’s Transcriber settings, then tailor options for use cases such as multilingual receptionist, healthcare, or fintech agents. Base pricing is listed at $0.45 per hour of session duration, with keyterms included and optional add-ons for prompting, diarization, voice focus, and medical mode.
