Cartesia offers ultra-fast text-to-speech (Sonic) and speech-to-text (Ink) APIs. It uses a credit-based subscription model starting at $5/mo, with a free tier providing 20,000 credits monthly for development.
Free tier present — value not quantified
This provider offers a free tier, but its terms don’t convert cleanly into a USD figure (e.g. request-count limits or capacity-dependent pools). We refuse to print a misleading zero here. See the note below and the official pricing page for the exact limits.
note: No public free-tier information found (researched 2026-08-29).
