How are silence, pauses in speech and interrupted translations billed?

Billing is determined for a whole round, from audio capture through stopping and finalization. On a phone, each start-to-stop speaking turn is a round. On a computer, a round runs from starting or resuming until pausing, changing language or voice, or ending.

If a round finishes normally with nonempty translated text, all source audio actually submitted counts, including natural pauses and silence within it. A round with no translated text, such as pure silence or source transcription only, is not charged. If interruption, timeout or an error affecting translation completeness prevents normal confirmation, the whole round is uncharged and its reservation is released, even if some translation appeared. Other previously successful rounds remain charged.

A translated-audio playback or output problem alone does not automatically waive the charge if the subtitle translation completes normally, because subtitles and translated speech have the same rate. Seeing one translated sentence does not mean the whole round has settled.
