Aurelo User Guide

Aurelo is a professional live accessibility and translation system that uses artificial intelligence for real-time captions, text translation, and optional spoken voice translation. The software supports over 60 languages and is designed specifically for church services, conferences, and live events.

1. Download and Installation

Step 1: Download the Software

• Visit dash.aurelolive.com/downloads
• Choose the version for your operating system (macOS or Windows)
• The free plan includes 2 hours of translation time per month, forever — no credit card required

Step 2: Installation

2. Computer Setup and Connection

Recommended: Direct Connection to Mixer

• Connect your computer with an audio cable directly to the mixing console
• Use a USB audio interface or jack cable
• This provides clean sound from the microphone without ambient noise
• → Significantly improves recognition and translation quality

Alternative: Built-in Microphone

• The laptop's built-in microphone can be used

Selecting Audio Device in the Program

In the top bar of the program, there are two audio level indicators:

• First one (with microphone icon) is for input audio - select your microphone or audio interface here
• Second one (with speaker icon) is for output audio - the translated voice
• Click on the indicator to select a device from the dropdown menu
• You can mute/unmute the input or output by clicking directly on the microphone or speaker icon

3. Live Test Mode (First Run)

When you log in for the first time, Aurelo opens directly on the Live page in Live Test Mode. This is a guided real test with your microphone (not a demo) and uses your normal quota minutes.

How It Works

• You will see a What to Expect card, language selection, and a Start Live Test button
• Before starting, some options are locked until the test begins (for example, Settings, Listeners, and Enable listener access)
• Audio remains available so you can configure audio devices anytime

Step 1: Select Languages

• Choose Source Language (Input) and Target Language (Output)
• Then press Start Live Test

Step 2: Run the Test

• Live output starts in real time
• Locked tabs and actions are unlocked while the test is running

Step 3: Stop and Exit Test Mode

• Press Stop Test to end the test session
• After your first stop, you will see Set up for real service
• When you choose it, Live Test Mode is completed and you move to normal operation

Live Test Mode is also completed automatically if you:

• Press Enable listener access
• Select a professional/non-microphone input device in Audio and press Save

4.4 Translation Mode

4.5 Additional Instructions

Aurelo includes one main instructions area for speech recognition context, plus extra fields for important terms and preferred translations when Translation is enabled.

You can use this section for special instructions such as:

• Specific terminology
• Names of people or places
• Event context
• Words Aurelo should recognize exactly as spoken
• Specific source words that should always translate in a certain way when Translation is enabled

You can also add:

• Terms — words or phrases Aurelo should recognize correctly
• Translation terms — source-to-target word pairs that should always translate the same way. This section is shown only when Translation is enabled.

4.6 Real-Time Delivery Controls

When using real-time translation or Voice Mode, Aurelo also provides extra controls to shape how speech is grouped before it is spoken:

• Pause Detection Mode — waits for short speech pauses before speaking a chunk
• Auto Segment Management — automatically balances smoothness and speed during live playback
• Wait For Punctuation — tries to hold a chunk until it ends more naturally
• Number of phrases combined before speaking — controls how quickly Aurelo speaks vs. how much context it waits for

5. How Listeners Receive Captions, Translation, or Voice

Option A: Listening via Phone (QR Code)

This is the easiest way - listeners use their own phones. Depending on your active mode, the same listener page can show captions, translated text, or translated audio with text.

Step 1: Start Listener Access

• In the top bar of the program, next to the translation button, there is an "Enable listener access" button
• Press "Enable listener access" - the button will turn orange and show "Disable listener access"
• This turns on local listener access and generates the QR code and local listener link

Step 2: Configure Languages and Access Mode

• Before starting the session, open Settings and choose the Primary Target Language (Audio Output)
• Under Languages Available to Internet Listeners, add the other languages needed for this service
• Go to "Live" from the navigation
• Open the "Network Streaming" section (click the arrow to expand)
• Local WiFi access stays available with the primary target language as soon as listener access is enabled
• Turn on Internet listeners to let listeners choose from the languages you enabled, connect over mobile data, or listen remotely
• Use the Local WiFi / Internet view buttons to switch between the two sharing modes

Step 3: Choose the Correct Listener Link

• If more than one network connection is detected, choose the local network your listeners are actually using
• The QR code and displayed link update based on the selected local network or internet view
• You can copy the URL, open it in a browser, or let listeners scan the QR code

Step 4: Connect Listeners

• Listeners scan the QR code with their phone camera
• Or open the correct listener link directly in the browser
• Internet listeners select one of the languages you made available; local WiFi listeners receive the primary target language

Requirements for Listeners:

• Phone/tablet/laptop with web browser
• Headphones (wired or Bluetooth) when Voice Mode is active
• For local listening, connection to the same local WiFi network as the computer running Aurelo
• For internet listening, use the public listener link from the Internet view — listeners can connect from mobile data or remote locations
• No app installation required!

What Listeners See:

• Captions-only mode: original-language live captions, with no translated audio stream
• Translation-only mode: translated text, with no audio stream
• Voice Mode: translated text and spoken translated audio

Option B: Existing Translation System

If you have a professional translation system with receivers:

1. Connect the computer's audio output to:
   • Directly to the system transmitter via jack cable
   • Or to the mixer via jack/USB, then to the transmitter
2. Listeners use standard receivers and headphones

6. Listeners & Caption Pages

The Listeners page contains the local and internet sharing links, QR codes, and dedicated browser pages for captions and translated text.

• Captions page — displays real-time captions of the spoken audio in the original language. Ideal for deaf/hard-of-hearing accessibility.
• Translation page — displays translated text in the target language, updated in real time as the speaker talks. This page is shown when Translation is enabled.

Accessing Caption Pages

Each output has its own URL when that output is available:

• Go to "Listeners" from the menu in the Aurelo app
• Captions URL: http://192.168.1.100:3030/subtitles — shows original language captions
• Translation URL: http://192.168.1.100:3030/subtitles/translation — shows translated text when Translation is enabled
• If more than one local network is available, choose the correct network for your audience before sharing the URL or QR code
• You can download the QR code directly from the Listeners page for sharing or printing
• You can configure settings such as font size, number of lines, padding, line spacing, font, and background for the available pages

Use Cases for Caption Pages

The caption and translation browser pages can be used in multiple ways:

1. OBS / Live Streaming

To display Aurelo captions or translated text in OBS Studio:

1. Open the Aurelo app and log in.
2. Turn on "Enable listener access" in the top bar. This turns on local sharing and generates the local browser URLs.
3. In the Aurelo app, open "Listeners".
4. If needed, choose the correct local network before copying the browser URL.
5. Copy either the Captions URL or the Translation URL, depending on what you want to display.
6. Open OBS Studio.
7. In the Sources section, click "+" and add a Browser Source.
8. Paste the Aurelo URL into the Browser Source settings.
9. Adjust the settings as needed, such as size, position, and refresh behavior, then click "OK".

Once set up, Aurelo live captions or translated text appear directly in your OBS scene and stream.

2. Venue Screens (ProPresenter, etc.)

• Add the captions or translation URL as a browser source in ProPresenter or similar presentation software
• Display live captions or translated text on screens in the venue
• Helps attendees who cannot hear well, prefer to read along, or speak a different language

3. Personal Devices

• Open either browser URL in any web browser
• Works on phones, tablets, laptops, or smart TVs
• No app installation required
• Each person can view captions or translated text on their own device

7. Starting a Session

In the top bar of the program, there are two buttons:

Steps to Start:

1. Open Aurelo and log into your account
2. Select the correct audio device from the top bar
3. If you want QR code for phones - press "Enable listener access"
4. If you want remote/mobile-data listening, open Network Streaming and turn on Internet listeners
5. Press "Start" to begin the session
6. The indicator will turn green when the system is active
7. Speak into the microphone - captions, translated text, or voice output will appear based on your Settings

To stop: Press "Stop" (the red button)

8. Usage Tracking

In Settings you can see:

9. Troubleshooting

Problem: No Sound in Voice Mode

• Check if the input audio device is correctly selected from the top bar
• Check if the microphone indicator responds when speaking
• Make sure the computer sound is not muted
• Check if the microphone icon is not crossed out (muted)
• If listeners use Android Chrome, ask them to tap Enable Audio on the listener page before expecting browser audio playback

Problem: Listeners Cannot Connect

• Make sure you pressed "Enable listener access" from the top bar
• If you are using the public listener link, make sure Internet listeners is turned on in the Network Streaming section
• If you are using local listening, check that the computer and phones are on the same WiFi network
• If Aurelo shows more than one local network, make sure you selected the correct one for your listeners
• Check whether your router or access point has client isolation / AP isolation / guest network isolation enabled, which can block phones from reaching the Aurelo computer even on the same WiFi
• If Aurelo asked for network access when it first started, make sure you clicked Allow
• If needed, open your operating system firewall settings later and allow Aurelo network access on both Private and Public networks
• If you are using internet listening, confirm attendees opened the correct public listener link
• Try restarting (Disable listener access → Enable listener access)
• Check if the QR code is displayed in the Network Streaming section

Problem: Listeners See Captions but Not Translation

• Open Settings → Live Output and make sure Translation is enabled
• If Translation is disabled or not included in the plan, listeners will receive captions-only output
• If Voice Mode is enabled, Translation is enabled automatically because the voice is generated from translated text

Problem: Poor Recognition Quality

• Use direct connection to mixer instead of built-in microphone
• Reduce ambient noise
• Check the input signal level in the top bar

Problem: Quota Exhausted

• Press Manage Subscription in Settings to upgrade your plan
• Quota resets at the beginning of each period
