Read the full Google Cloud Text-to-Speech review

Google Cloud Text-to-Speech is a developer-focused TTS API rather than a creator app — there is no Studio-style editor or voice-cloning UI. It's billed purely per character, with WaveNet voices at $4 per million characters, Neural2 voices at $16 per million characters, and the newer Chirp 3 HD voices at $30 per million characters. Free monthly allowances (up to 4 million characters for WaveNet/Standard, up to 1 million for Chirp 3/Neural2/Studio) make it cheap to prototype. It fits teams already on Google Cloud who need reliable, scalable TTS wired into infrastructure 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.
