Collection notes
Text to speech (model tts-rt-v2 in the price comparison) is pay as you go and billed by tokens: $4.00 per 1M input text tokens and $21.50 per 1M output audio tokens, about $0.70 per hour of generated speech. The page gives approximate conversions (1 character ≈ 0.3 input text tokens; 1 hour of speech ≈ 15,000 input text tokens and ≈ 30,000 output audio tokens); it states no price per character, so none is entered.
