Text-to-Speech Cost Calculator

Calculate the API cost of generating speech audio from text.

About Text-to-Speech Cost Calculator

Text-to-speech providers typically bill per character (or per 1,000/1M characters) of input text synthesized into audio. This calculator multiplies your total character count by the provider's per-character rate. Premium voice cloning or higher-fidelity voice models often carry a price premium over standard voices.

Formula

total_cost = characters × rate_per_character

characters
Total character count of input text
rate_per_character
Provider cost per character synthesized

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Do longer texts cost proportionally more?

Yes, cost scales linearly with character count under standard per-character pricing models.

Does voice choice affect price?

Some providers charge more for premium/cloned voices versus standard voices; adjust the rate to reflect your specific voice tier.

Are SSML tags counted as characters?

Most providers count all submitted characters including SSML markup, so minimize unnecessary markup to reduce billed characters.
