Questions
Can I start without talking to sales?
Yes, you can start on Inworld AI's On-Demand plan without talking to sales, by creating an API key in the Inworld Portal. On-Demand is free to start and includes up to 70 minutes of text to speech or 400 minutes of speech to text. Growth cuts Realtime TTS-2 Flash to less than half the On-Demand rate, $7 per 1M characters against $15.
What does the Inworld AI Enterprise plan include?
Inworld AI's Enterprise plan adds custom limits, an SLA and DPA, EU and India data residency, invoicing, and a dedicated account manager with a shared Slack channel. Enterprise rates are set with our team, go down to $10 per 1M characters for Realtime TTS-2 and $5 for Realtime TTS-2 Flash, and come with price matching.
How do I estimate my monthly text to speech volume?
Inworld AI measures text to speech volume in characters, and one minute of speech is about 1,000 characters, so 10M characters a month is about 10,000 minutes. The form asks for your monthly characters, from under 10M to more than 1B. At Growth rates, 10M characters of Realtime TTS-2 Flash costs about $70.
Which security and compliance standards does Inworld AI meet?
Inworld AI is SOC 2 Type II certified and HIPAA and GDPR compliant, and zero data retention, available on Enterprise plans and as an add-on on the Growth plan, covers text to speech, speech to text, hosted LLMs and speech to speech. Enterprise plans add EU and India data residency, SAML single sign-on and SCIM provisioning.
Does Inworld AI offer volume discounts?
Yes, Inworld AI text to speech rates fall at each step from On-Demand through four paid plans to Enterprise, where rates are set for your volume. On Enterprise, spend on one product lowers the others on one combined commit, so text to speech, speech to text and LLM usage cost less together. Realtime TTS-2 falls from $25 per 1M characters on demand to $12.50 on Growth, and Realtime TTS-2 Flash reaches $5 on Enterprise, up to 16× lower than the $80 Eleven v4, ElevenLabs' newest model, lists.
