What each one can and cannot do, checked against the vendor’s own documentation. Short answer: StreamVox and Tingdong are the two apps in this category that both show subtitles and speak. StreamVox runs on Windows, Mac and iPhone, starts at $8.99/month for 40 hours, and reads translations aloud in 21 languages (beta). Tingdong runs on Mac and Windows at $5.99/month, auto-detects 60+ languages, and on the Mac is built around the two-way call (Website version): your translated voice goes into the conversation, not just their words onto your screen. Tingdong for iPhone and iPad is a separate app on the App Store, for the people around you. Pick by platform first, then by whether you need to talk back.

Where a row says on-device or offline: Tingdong runs recognition and translation on a dedicated streaming engine, not on your Mac. Why that is the trade we chose — model size, 60+ auto-detected languages, simultaneous pacing — is on one page: why not on-device, and why it costs money.
Pick StreamVox if you want one subscription that follows you across devices and you are happy to pay $8.99 and up for it. Pick Tingdong if you live on a Mac and the goal is a conversation, not a transcript: it is the cheaper of the two, it detects the language for you instead of asking you to pick, and it is the only one of the pair that puts your own translated voice into the call (Website version). On Windows, Tingdong subtitles and reads aloud but sends nothing into calls. On iPhone and iPad, Tingdong for iPhone and iPad captions the people around you; phone calls still go through the Mac. Both let you try before paying.
Yes — StreamVox is on the Mac App Store, with Windows and iPhone versions too. Tingdong runs on Mac and Windows, with its call features on the Mac; Tingdong for iPhone and iPad is on the App Store, for the people around you.
Tingdong: $5.99/month or $59.99/year, versus StreamVox Pro at $8.99/month. StreamVox’s free tier is 15 minutes a day, forever; Tingdong’s is a one-time free trial of about 100 minutes of subtitles.
Yes. StreamVox added text-to-speech in beta for 21 languages; Tingdong’s Read aloud is built in and is the basis of its call mode, where the other party hears your translated voice (Mac Website version).
Both route iPhone calls to the Mac — StreamVox through Continuity, Tingdong through a Bluetooth handoff. The difference is direction: Tingdong interprets both sides, so the person you called hears your words in their language (Mac Website version).
