How it works
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
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.
