Tingdong: Live Captions & Real-Time Translation for Mac & Windows, Tingdong, Tingdong, 2026, Home page, pricing section and the fine print under the pricing cards.

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. Tingdong for iPhone and iPad is bought in the App Store and is not in this row.
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 yearly plan is left out because the page does not state its credits separately. The per-hour figure is converted: $5.99 divided by 1000 minutes is $0.00599 per minute, times 60 is $0.3594 per hour.
