Caption Assist
CA C3
QUICK START GUIDE
The Caption Assist (CA C3) is a professional, hardware-
based live captioning system. During a video call or other
live event, the Caption Assist can use the power of the
Google Cloud to put real time captions on any video
source. Many languages and dialects can be selected for
captioning, and is a perfect fit for churches, classrooms and
other presentations.
General Installation
Connecting the Video Source and Outputs
IMPORTANT: Be sure to power down the Caption Assist
before connecting or disconnecting any devices. The
Caption Assist will automatically detect new devices upon
turning the power on.
HDMI Connectors
To connect HDMI video:
HDMI Input into Caption Assist: Using HDMI video cable,
connect the cable to the HDMI In port on the back panel of
the Caption Assist.
HDMI Output from Caption Assist: Using HDMI video
cable, connect the cable to the HDMI Out port on the back
of the Caption Assist to HDMI In on a HDMI display.
Required Use of Multiple Devices
The output typically cannot be connected to the same
device as the input. For example, laptops do not have an
HDMI In port, but do have an HDMI Out port.
Any data sent to the HDMI Output is also sent out via a
digital stream, which is viewable from the SoundPlus Media
Player.
Displaying the stream or output into the same device as the
input will cause video to show a video of itself, creating a
visual echo. For more explanation, see the full manual.
Connecting USB Devices
Connect microphones or other USB devices to any USB
port on the Caption Assist. The system supports up to 5
USB 3.0 devices and 1 USB B device.
For a standard microphone, connect using the included
USB to XLR cable.
Connect the USB Mouse to use the menu system for
configuring the device.
Power On
To power on the Caption Assist:
1. Plug the power cord into the back of the Caption Assist
and then into any grounded outlet.
2. Plug the power cords from any video source(s),
display(s), or other devices into any grounded outlet.
3. Turn on each of the connected units, and then press
the power button on the front panel of the Caption
Assist.
NOTE: In order for the Caption Assist to properly sync with
the video signals, the sources should be turned on
first.
After a moment, a Caption Assist splash screen will appear,
followed by the initializing of the ports, and ending with a
copyright message.
After the startup process, the default input source will be
shown.
If this process is dierent for you, recheck your installation
and power on again. Call Williams AV for support if it is still
unsuccessful.

A network connection to the Caption Assist is required. The
Caption Assist depends on access to the Google Cloud to
receive its captioning data.

the display screen using the included mouse. The
Main Menu appears. Select the Network option. The
Network Menu appears.

Caption Assist App
The Caption Assist app is available to help purchase

To connect the app to your Caption Assist, scan the QR
code visible in the SoundPlus Media Player.
SoundPlus Media Player
The Caption Assist can display streaming video output
over the SoundPlus Media Player. The video will match any
HDMI video output. The player will let you select from any
stream sent from a Caption Assist system.
Downloading the Software
Download the software from www.williamsav.com. The
firmware can be found on the product page, or under the
Support - Downloads section.
Installing the Video Software
After downloading the software, unzip the file that you’ve
downloaded and run the installer. Follow the installer’s
prompts and instructions until the installation is complete.
Using the Video Software
Once installed, open the web conference software of your
choice. While the web conference software is running, also
open the SoundPlus Media Player.
During your web conference, share the SoundPlus Media
Player like you would a document or your screen. For
instructions on sharing your screen, please view your web
conference software’s documentation.
Captioning Sessions
Purchasing Hours
Caption Assist requires a fee in order to be used. Google
charges for use of their cloud services, which is how
Caption Assist receives its captioning.
Hours can be purchased in groups of 8-hours, but the hours
do not need to be used continuously. For instance, you can
run one 4-hour session on a Monday, a 2-hour session on
Thursday, and use the remaining 2-hours the next week.
Multiple groups of hours can be purchased at one time, if
desired. If you have a 4-hour meeting every day, you can
purchase three 8-hour groups at once for a total of 24
hours of live captioning. Hours do not expire.
To purchase hours, scan the QR code on the Caption
Assist’s output display with the app. Once connected, tap
the shopping cart icon in the bottom right corner of the
screen.
Starting a Session
Sessions may be started from the Caption Assist App, or by
using a USB mouse connected to the Caption Assist.
If using a mouse:
On the toolbar or Caption Assist App, click the green START
button with the provided mouse.
If using the app:
Scan the QR code on the output display to connect to your
Caption Assist device. Once connected, tap on the START
button.
Stopping a Session
Tap STOP on the toolbar or Caption Assist app to pause the
session. When stopped, you can switch languages, take a
break, or finish your session.
Language Selection
The language and dialect of the audio that is being
captioned must be selected. Selecting the correct dialect
is important. For example, English in South Africa sounds
drastically dierent from English in Canada. Not all
languages have dialects, however.
In the Language Selection menu, find the language first and
then look at the two character code next to the language.
Each letter will be in a small box. These boxed letters
indicate the dialect. For a full lists of languages and dialect
codes, see the full user manual.
