How billing works

  • Text-to-Speech (TTS) bills on the size of the input text, measured in UTF-8 bytes.
    One million UTF-8 bytes ≈ 1 MB ≈ about 180,000 English words.
  • Automatic Speech Recognition (ASR)
    Charges are based on the duration of audio processed, rounded up to the nearest second.
