SpeechifyAI publishes one price list covering both of its APIs — text-to-speech and realtime voice agents. Paid usage runs on a prepaid balance drawn down at the real per-character and per-minute rate, with optional auto top-up, rather than on opaque credit buckets. Plans are $10/month (Starter), $99/month (Pro) and $499/month (Scale), with a free tier and a custom Enterprise tier.

Each plan is an allowance plus a rate, and the rate improves as you move up: text-to-speech includes 1M characters then $10 per 1M on Starter, 3M then $8 per 1M on Pro, and 10M then $6 per 1M on Scale. Voice agents follow the same shape — 120 minutes then $0.075/minute, 1,200 minutes then $0.07/minute, and 6,000 minutes then $0.068/minute — with Enterprise quoted from $0.06/minute. The agent rate is all-in: LLM inference, speech-to-text, text-to-speech and telephony orchestration are one line item with no passthrough billing. Plans also differ on concurrency (3, 6, 12 and 30 concurrent calls) and included phone numbers (BYOC only, 1, 5 and 20).

The free tier is hard-capped at 50,000 characters and 60 agent minutes a month, so it cannot produce an overage bill; every paid plan switches to auto top-up instead of a cap.
