Short answer: StreamVox and Tingdong are the two apps in this category that both caption 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 is Mac-only at $4.99/month, auto-detects 60 languages, and is built around the two-way call: your translated voice goes into the conversation, not just their words onto your screen. Pick by platform first, then by whether you need to talk back.

Pick StreamVox if you need Windows or iPhone, or 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. Both let you try before paying.
