Open the original- What it measures
- Inworld's own list price for its STT 1 model (inworld/inworld-stt-1) on the On-Demand plan, which has no monthly fee. The page states the rate per hour of audio. The billing documentation says On-Demand accounts include up to 400 minutes of STT for free.
- What it does not show
- The page does not split the STT 1 rate by mode. The row is assigned to streaming because the page describes speech to text as real-time transcription. Synchronous and asynchronous file requests are billed by audio duration, but no separate batch price is listed. Negotiated and Enterprise prices are not included.
