About Universal-3 Pro (AssemblyAI)
Universal-3 Pro is AssemblyAI's first promptable speech language model, allowing developers to guide transcription behavior with plain-language prompts of up to 1,500 words to improve accuracy on specialized vocabulary, speaker labeling, and domain-specific entities. It supports six languages (English, Spanish, Portuguese, French, German, Italian) with native code-switching, outperforms competing ASR models on rare-word accuracy by up to 45% fewer errors, and is available in both async and real-time streaming modes for voice agent applications. Alternatives: Deepgram Nova-3 (comparable accuracy, lower per-minute cost, sub-300ms latency), OpenAI Whisper (open-source, multilingual, self-hostable), Google Cloud Speech-to-Text Chirp 2 (broadest language coverage, native BigQuery integration), Amazon Transcribe (fully managed AWS-native ASR with streaming support).
