Calculate the API cost of generating speech audio from text.
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.
total_cost = characters × rate_per_character
Yes, cost scales linearly with character count under standard per-character pricing models.
Some providers charge more for premium/cloned voices versus standard voices; adjust the rate to reflect your specific voice tier.
Most providers count all submitted characters including SSML markup, so minimize unnecessary markup to reduce billed characters.
