How Much Does AI Text to Speech Actually Cost? (2026)
Pricing pages for AI voice tools are oddly hard to parse: characters, credits, tiers, 'from $X'. Here's what you actually pay, translated into numbers you can plan around — plus the couple of things that quietly run the bill up.
Why it's priced by characters, not minutes
Nearly every tool charges by how much text you convert, not by audio length, because characters are what the model processes. A workable rule of thumb: about 1,000 characters is roughly a minute of speech. So a 5-minute script (~5,000 characters) is the unit of cost to think in.
The three things that move the price
Length is the obvious one. The second is model quality — the fastest models cost the least per character, the highest-fidelity ones more. The third is the feature: dubbing and music generation run several times more per minute than plain text to speech, because there's far more computation behind them.
What 'free' really gets you
Free tiers are for trying, not for running a business on. LyreWave's 50,000 free credits, for instance, comfortably cover testing every feature and narrating a few short videos; heavy or commercial use is what the paid monthly plans are for.
How to avoid a surprise bill
Use a tool that shows the estimated cost before you generate, and watch two habits: regenerating long scripts over and over (each pass costs again), and defaulting to the priciest model when a cheaper one would do. For most narration, the fast or mid model is indistinguishable to listeners.
