Text to speech.
Have alerts read messages aloud: a tip note, a resub message, a redemption. Text to speech turns those into spoken audio that plays through your overlay.
Turning it on
Text to speech is configured per alert in the designer. Pick a voice, set the volume, and choose how it behaves alongside any sound or video in the alert:
| Media mode | Behavior |
|---|---|
| Just play | Speech and the alert sound or video play at the same time. |
| Duck | The alert sound or video drops to a lower volume while the voice is talking, then comes back. |
| Queue | The alert sound or video plays first, then the voice. |
You can also set a short delay before the voice starts, and override the voice or speed on an individual text block.
Voices
Available voices come from the speech provider configured for the platform (for example ElevenLabs or Amazon Polly). You choose from the voice list in the designer.
Pronunciation
Voices sometimes mangle names, in-jokes or game terms. In Settings, under Pronunciation overrides, add a word and how it should sound, and speech will use your version everywhere it reads that word.
| Word | Pronounce as |
|---|---|
| Bob | bahb |
| Cwiczenia | vee-cheh-nya |
| xQc | ex cue see |
Quotas
Each account has a monthly character allowance for speech. Generated audio is cached, so re-firing the same message does not spend your allowance twice.
Speech plays through the overlay browser source, the same as alert sounds. Keep that source in your streaming software audio mixer so you can balance it against your game and mic.
