How to Add Text-to-Speech for Donations During a Live Stream

Set up donation TTS by enabling it on your tip alert, adding the alert source to your scene, and testing both the alert and its audio before going live.

To have donation messages read aloud during a live stream, enable text-to-speech (TTS) for the tip alert in your alert service, add that service’s alert widget or overlay to your streaming scene, and test the result—including its audio—in your streaming software. The exact dashboard steps depend on whether you use Streamlabs, StreamElements, or another provider.

Before you begin

Streaming dashboards often call donations “tips.” The TTS setting belongs to the tip alert event, and the matching alert widget or overlay must be active in the scene you broadcast. A dashboard setting by itself does not put an alert into your live output.

  • Identify the tipping page and alert service your viewers use. Configure that service rather than a different provider.
  • Have access to the service dashboard and the streaming scene where alerts should appear.
  • Decide how to handle message length, minimum tip amounts, profanity, and spam before allowing donor text to be read aloud.

No special microphone, capture card, headset, or stream controller is required for this alert setup; the documented workflows use software settings and an alert source.

Set up donation TTS with Streamlabs

  1. Add the alert source to your scene. In OBS or other streaming software, copy the Alert Box widget URL from Streamlabs and add it as a Browser Source. In Streamlabs Desktop, use its native Alert Box source; the Streamlabs OBS plugin is another documented option.
  2. Open the alert settings. Sign in at Streamlabs.com and open Alert Box.
  3. Choose the event. Select Tips (or Bits if you also want TTS for Bits), then open Text-to-Speech.
  4. Choose controls. Set a minimum tip amount if you want only qualifying tips read aloud, select a voice, and configure the spam filter. Streamlabs’ guide says its TTS offers over 50 voices, including multiple languages; this is the vendor’s figure in its November 5, 2025 guide and may change.
  5. Enable and save. Turn on TTS for the event and save your changes.
  6. Test the broadcast path. Use the dashboard test dropdown, Live Preview, or the streaming software’s test widgets. Confirm that the alert appears and that speech is audible in the stream output, not just in a dashboard preview.

Streamlabs says its profanity filter is off by default and recommends starting at Low or Medium. Its alert settings also offer default and custom profanity filters, including options to replace, hide, or suppress alerts containing blocked words. Test the chosen level with legitimate messages as well as unwanted ones. Streamlabs says Alert Box itself is free; it describes Ultra as an optional way to access a larger theme library, not a requirement for donation TTS. Streamlabs’ TTS setup guide and alert setup guide document these controls and source options.

  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

Set up donation TTS with StreamElements

  1. Create or edit an overlay. In StreamElements, open the overlay you want to use and add an AlertBox widget.
  2. Configure the tip alert. Open the tip alert settings, find TTS settings, enable text-to-speech, and choose a voice.
  3. Check alert variations. Review any variations as well as the base tip alert, because a variation can override the base configuration.
  4. Connect tipping. Make sure tipping is configured and connected to the page viewers will use. StreamElements names PayPal and SE.Pay as options; provider availability and eligibility can vary.
  5. Set message safeguards. Review provider settings such as minimum and maximum amounts, maximum message length, and moderation controls. If the overlay is separate from your streaming software, add its URL to OBS as a Browser Source.
  6. Test in the actual scene. Trigger a test alert, confirm its visual display and speech, and check that the overlay is active in the scene you plan to broadcast.

StreamElements documents standard and custom profanity protection, message filters, repeated-character TTS anti-spam, and optional manual approval of tips. Filtered events remain in the activity feed but do not trigger an alert; tip moderation settings do not affect fund transfers. Check the service’s instructions for your platform rather than assuming every platform uses identical menus. See StreamElements’ tip alert guide, tipping setup guide, and tip moderation guide.

Choose the workflow that matches your setup

If you already have a tipping page and alert provider, start there so the payment, message, and alert are connected. If you are choosing between the documented options, compare the workflow and safeguards that matter to your stream:

Consideration Streamlabs StreamElements
Adding alerts to OBS Browser Source using the Alert Box URL; Streamlabs also documents a native source in Streamlabs Desktop and a plugin route. Overlay URL added as a Browser Source.
Tip connection Use the tipping page associated with your Streamlabs alert setup. PayPal and SE.Pay are named options; check provider availability and eligibility for your account.
Message safeguards Minimum tip amount, spam filter, and default or custom profanity controls are documented. Message filters, repeated-character TTS anti-spam, profanity protection, and optional manual tip approval are documented.
Customization Alert duration, text, sound, variations, and themes are documented. AlertBox and overlay settings are documented.

Neither method removes the need to test speech through your streaming software. A preview can look correct while audio routing or browser-source settings prevent viewers from hearing it.

Moderate messages before they reach the stream

TTS turns viewer-submitted text into live audio, so an unfiltered message can be offensive or disruptive. Set safeguards before enabling freeform messages, rather than waiting for a bad alert to happen.

Troubleshoot donation TTS

What you notice What to check What to do
No alert appears The alert source may be missing from the active scene, using the wrong widget URL, or showing unsaved settings. Confirm the correct source or overlay URL, save the dashboard settings, reload the browser source, and test in the scene you are broadcasting.
The visual alert works but speech is missing TTS may be disabled for the tip event, or the voice or event setting may not have been saved. Reopen the tip alert’s TTS settings, confirm it is enabled for the right event, save, and run a fresh test.
Speech is audible in preview but not to viewers Browser-source audio may not be reaching the stream mix, or the wrong audio device may be selected. Check the selected audio device and browser-source audio controls or monitoring options. Test the actual streaming output rather than relying on the dashboard preview.
Some tips do not trigger TTS A minimum amount, filter, moderation setting, or alert variation may prevent the message from triggering. Review the threshold and moderation rules. In StreamElements, inspect the relevant variation as well as the base alert.
StreamElements alerts seem paused or muted The activity feed may have alerts muted or paused. Check those controls and test the alert again. StreamElements’ tip alert guide and OBS troubleshooting guide cover alert and audio checks.

Or let it run in the cloud

Donation TTS is separate from keeping a YouTube channel live around the clock. If your goal is a continuous YouTube stream from uploaded videos, StreamNeo runs that stream in the cloud: upload a recording or build a playlist, add your YouTube stream key once, and go live. It does not read donation messages or stream from a camera.
