Clevercast

Pros: Clevercast's AI speech-to-text and machine translation for live streaming is wonderfully accurate. Subtitles and audio translations are always in-sync. We've used it on multiple occasions for events with up to 16 languages, it always worked fine without any issues. Also a nice feature: Clevercast lets you simulcast streams with with audio and subtitle language of choice, for example to YouTube (finally a solution for the low quality of YouTube subs). Finally, their live stream quality is great, with stable global delivery (even in China).

Cons: They have a ton of features, some part of their basic solution, some at an additional cost. So it is not always clear which feature is optional and which isn't. I recommend to just ask their support team, which is very responsive. Also, because of all these features, their platform may seem a bit challenging at first. Again, as a new user, be sure to contact their support. If necessary, request a quick runthrough in a virtual meeting. For me, this provided immediate clarity.

Overall: If you need to do live streaming with AI-powered subtitles and/or multiple audio languages, Clevercast is the way to go. Take a look at their website for their many features.

Pros: Clevercast is a multilingual live streaming platform, which I've used in the past for remote interpretation. This time my client needed subtitles in 12 languages, including Chinese. This is possible through speech-to-text (AI). The AI quality is already very good, but even better is that someone can still edit the captions in real-time, before they get translated by the AI and streamed. This way, you can correct small AI errors, for example in names.

Cons: The service is not cheap, but the platform works great and their support is also very good.

Overall: It is really a unique platform, which uses the live streaming latency in a very creative way. Streaming quality is great and subtitles are always kept in sync.

Pros: It's like a Swiss army knife for multilingual livestreams, with features you can't find elsewhere. Just about everything is possible: broadcast with multiple audio streams, remote interpretation, multilingual captions, AI captioning and translation ... And most importantly: everything just works without a hitch.

You can paste an embed code for their multilingual player to appear in your event platform (Swapcard in our case).

Cons: If your livestream generates a lot of data traffic, their monthly plans can be a little pricey. They don't do 'pay as you go', but you can solve that by taking an annual plan.
The price is worth it, though. Their global livestream delivery is better (high quality, seamless, no viewer complaints) than all other solutions we've tried before.

Overall: Great overall experience. We started out using Clevercast for livestreams with simultaneous interpretation. But because their platform works so well, we now use it for all our streaming needs. Great support as well.
