Text-to-Speech Cost: What You Pay to Generate Audio
Text-to-speech is billed on the text you send, typically per character or per million characters, not on the length of the audio. That makes the cost easy to predict once you count your script.
Count characters, not minutes
Because TTS prices on input characters, your budget scales with script length. Long-form narration and audiobooks are large character counts, so per-million rates matter more there than for short prompts.
Voice tier and re-generation
Premium and cloned voices often cost more than standard ones, and edits mean regenerating whole passages. Lock the script before generating, and pick the voice tier that fits the use to avoid paying twice.
