Assemblyai upgrades realtime STT to Universal-3.5 with 18-language support
What happened
Between the Jun 22, 2026 and Jun 29, 2026 captures of Assemblyai's pricing page, Pulse recorded one change: New realtime STT model announced: a site-wide banner on the pricing page now reads "NEW - Universal-3.5 Pro Realtime is here." with a Learn more link; no such banner appeared in the prior version. Pulse files it as a packaging change (plan renamed) with a neutral direction. Pulse's latest capture (Aug 24, 2026) lists Voice Agent API at $4.5 per hour + $4.5 per hour, Universal-3 Pro at $0.21 per hour of audio, Universal-Streaming Multilingual at $0.15 per hour of audio, Universal-3 Pro Streaming at $0.45 per hour of audio and Universal-2 at $0.15 per hour of audio.
It lands 81 days after Assemblyai's previous change, "Assemblyai unifies audio limits with expanded 333h free allowance" (Apr 9, 2026). Before that Pulse recorded "Assemblyai Launches Medical Mode for Healthcare Transcription" (Apr 1, 2026) and "Assemblyai cuts flagship STT price 22% with Universal-3 Pro rebrand" (Apr 4, 2026). Assemblyai has been tracked since 2023-11-14.
In the same window Google Cloud, Deepgram, IBM and Otter also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
