Setup and technology
What do I need for live translation?
A laptop with a browser that receives the audio from the mixing desk or microphone, and a stable internet connection. You don’t need booths, transmitters or receivers.
Do my guests need an app?
No. Your guests scan a QR code, choose their language in the browser and hear the translation on their own phone. They don’t need an account.
Which headphones work?
All of them. Whether AirPods, Bluetooth earbuds or wired headphones: your guests simply use what they have with them. A few spare headphones at the entrance help anyone who has forgotten theirs.
Is Wi-Fi enough, or do I need a cable?
Wi-Fi works as long as it is stable. If the connection drops, the translation stops too. The safest option is therefore an Ethernet cable on the translation laptop. Connect it a few minutes before the start as well, so that everything is running when things begin.
Does everything have to be translated, including music and worship?
No. What is spoken gets translated. You can pause during the music and have only the sermon, the announcements or the talk translated. That saves hours too.
Can I also show the translation in the livestream?
Yes, as audio on the phone or as captions directly in the picture. How that works with YouTube is in YouTube livestream in multiple languages.
Languages and quality
Which languages can I translate into?
Into more than 80 languages, several at the same time too. Every guest chooses their own language and can read the captions as well.
How long is the delay?
With Streamlingo 2.0, your guests hear the translation after 3.1 seconds.
How accurate is the translation?
Very accurate with clear speech and good audio. In our experience, errors occur mostly with names, numbers, strong dialect and poor audio. A clean signal from the mixing desk therefore makes the biggest difference.
Does the system recognize which language is being spoken?
Yes, if you use automatic language detection. That is handy at events with changing speakers and languages. If your speaker always speaks the same language, you set it in the settings under “Fixed source language”. Then the translator voice stays constant. We enable processing exclusively in the EU for your account on request.
Can I also use Streamlingo for conversations?
Streamlingo is made for sermons, talks and lectures, that is, when one person is speaking. For conversations between two people, we currently don’t recommend it, because it doesn’t work reliably enough there yet.
Can I combine AI and human interpreters?
Yes. For each language you decide whether the AI translates or an interpreter does. You can read more in Interpreters or AI? Where live translation stands in 2026.
Costs and subscription
How is it billed?
Per language and per hour. If you translate one hour into one language, you use one hour. If you translate the same hour into two languages, that is two hours.
How many hours do I need?
The formula is simple: hours of programme × number of languages. A church service with one hour of sermon and announcements in one language therefore needs about four to five hours a month. With the calculator on our pricing page you can work out what you need in a few seconds.
What does Streamlingo cost?
There is a free plan. Subscriptions start at €55 a month for churches and non-profit organisations and at €110 for businesses, each incl. VAT. With the annual subscription you save 20%. It is still billed monthly, with a term of one year. You’ll find all plans on our pricing page.
Can I try Streamlingo first?
Yes. You can try Streamlingo for two hours free of charge, without a subscription.
What happens to my data?
Your content is not used to train AI, and the audio is not saved as a file. As a German company based in Karlsruhe, we take data protection very seriously. You’ll find all the details in our article on live translation and GDPR.
