With Live Captions you can show a live transcript of any LiveVoice audio channel in almost real time to your audience.

💭 What you should know first

AI Live Captions is a pay-as-you go feature that you can activate additionally to your LiveVoice account plan (day plan or subscription). It is billed by minute and invoiced afterwards. You find the pricing here.

Before you pay, you can try out Live Captions up to 20 minutes for free. Once you have used up the free minutes, you will only be able to use it if you add a payment method, or already have an active subscription or day plan (as this means you already provided a payment method). Minutes will then be billed to this payment method.

✌️ Types of subtitles

Apart from Live Captions that will show the live transcript of your audio channel, you can also set up translated subtitles as well as AI Voice Translation. To learn more about AI Translation setup go here.

📱 How subtitles can be displayed

You can provide subtitles to your audience in these ways:

• On attendees smartphones or tablets, using the LiveVoice mobile app
• On computers in the web browser, e.g. for online events
• On large screens at events, using the full screen scrolling mode
• As lower thirds showing subtitles on large video walls or on livestreams

See examples and more on that here.

⚙️ AI Live Captions Setup

Step 1: Create event and channels

a. Create an event

b. Add your first channel. Choose "Audio channel with live captions"

c. Define the language spoken on this channel.

You can also set more than one language, for example if different languages are spoken on stage, but we recommend to choose as few as possible as quality is better if only languages are chosen that are really needed.

d. Click "Next", give the channel a name and confirm the payment check box.

This is how the setup would look like:

Step 2: Start Audio channel

a. Connect audio: Connect audio mixing console to a laptop or PC (audio cable or USB, depending on your equipment).

b. Open LiveVoice: Open LiveVoice on the computer browser (open www.livevoice.io and enter the speaker code, or simply follow the sharing link you get in the admin panel; we recommend Chrome as browser)

c. Start Streaming: Click “Start” in the LiveVoice Lobby. The interface will turn orange, and you will see the mic level working. 

Step 3: Starting Live Captions

Live Captions will now start automatically as soon as a speaker starts streaming in this channel.

Make sure to stop the audio channel when you are done to avoid unnecessarry costs.

You can add more channels anytime and also add the Live Captions feature later to any already existing audio channel.

1. 1.
   Go to "Show options" of the channel you want to activate live captions for.
2. 2.
   Go to "+ Add feature"
3. 3.
   Choose the tab "AI Features" and add "Live Captions"

Glossary:

For SMART and PRO customers there is the option to create glossaries. This allows you to enhance the AI recognition of special words like company names, and make sure that the AI translates certain words exactly the way you want. Learn more about glossaries here.

☝️ IMPORTANT NOTES:

Costs depend on the time you are using the feature. It will be billed by minute. Once a week you will get the invoice for all used minutes within that week. If you have used minutes worth more than 250€ on a given day, you will be billed right away at the end of that day.

Minutes start counting as soon as a speaker starts a channel that has live captions enabled.

VAD (Voice Activity Detection) is set by default and will pause AI after 60 minutes to avoid unnecessary costs, but the responsibility for stopping the audio channel with AI captions is still with the customer/operator.
