Read the full Microsoft Azure AI Speech review

Microsoft Azure AI Speech is a developer-focused speech platform covering text-to-speech, speech-to-text and translation, billed per character rather than through a creator app. Prebuilt Neural voices run $16 per million characters, newer Neural HD voices $22 per million, and Custom Neural Voice (brand-specific voice creation) $24 per million plus hosting fees; a free tier includes 500K characters per month, and commitment tiers can push the effective rate as low as $7.50 per million. It's the natural fit for teams already standardized on Azure who need speech wired into existing infrastructure, security and compliance tooling rather than a polished creator workflow.

Runway is the most complete AI video platform in 2026. It ships state-of-the-art video generation, image-to-video, motion brush, inpainting, green screen and a real editor around it — so you can go from prompt to finished clip in one place. Credits burn quickly on the newest models, but if you take AI video seriously and want a professional workflow rather than a novelty app, Runway is the pick.
