Every live call uses several paid systems at once. You should understand which are included and which are passed through.
- Telephony or web RTC minutes
- Speech-to-text
- LLM reasoning
- Text-to-speech
- Recording/transcript storage
A per-minute number can hide a lot. Real pricing depends on the full pipeline: phone transport, speech recognition, the LLM, voice generation, storage, integrations, and retries.
