What it measures: Tingdong's live subtitles recognise speech on a streaming engine and show translated captions while people are still talking. The prices are for the Mac website version and the Windows app, in USD. The Pro plan is for heavy use and has the same features as the membership.
What it does not show: The subtitle price includes translation into the subtitle language, so it is not a price for speech recognition alone. Read aloud costs 8 credits a minute and is left out. Credits reset each month and unused ones do not carry over. The per-hour figure is converted: $29.99 divided by 5000 minutes is $0.005998 per minute, times 60 is $0.3599 per hour.
