AI text to speech is far cheaper than hiring voice talent, but pricing models vary. Most tools charge by credits or characters. Here's how it works and what you'll actually pay.
Most tools charge by credits or characters
Instead of a flat fee, AI voice tools usually deduct credits based on how much audio you generate — roughly proportional to the number of characters in your script and the model you choose. Higher-quality models cost a bit more per character.
What affects the cost
Three things drive cost: length (more text = more credits), model quality (fast models are cheaper than the highest-fidelity ones), and feature (dubbing and music cost more per minute than plain text to speech).
Free to start
You can try modern text to speech free — LyreWave gives every new account 15,000 credits with no credit card. Paid plans then add monthly credits as you scale, from a few dollars a month.
Estimate before you generate
Good tools show you the estimated credit cost before you hit generate, so there are no surprises. Plan your usage around your monthly credit allowance and top up only if you need more.
