Overview

TTSLabs is a text-to-speech service built for live streamers. Viewers trigger AI voices on stream through channel point rewards, tips or donations, and the speech plays during the live broadcast. The company stresses speed, so a message can land while the moment is still happening.

Speed

TTSLabs says about twenty seconds of speech renders in roughly three seconds and plays in order, so there is little waiting between a viewer's request and the alert going on air.

Control and moderation

Advanced profanity filtering checks every request before playback. The live queue stays under your control: every pending alert is listed in order, and you can skip, replay or clear anything waiting. This matters for streamers, since viewer-submitted text can be abusive or break platform rules.

Voices and clips

There is a large library of official, community, classic and custom AI voices, and you enable the ones that fit your channel. Examples on the site include voices labelled as streamers such as Mizkif, Alinity and Soda, community voices such as Kratos and GLaDOS, and generic voices like ASMR. Viewers can also drop sound clips into a message, which play inline with the speech.

Audience guide

A shareable page lists your enabled voices, clips and minimum amounts, so viewers know what they can use.

Setup

Getting live takes three steps. You sign in with Twitch and optionally link StreamElements or Streamlabs, so channel events and tips flow in. Then you enable voices and clips, set minimums and turn on the profanity filter. After that, your audience triggers the speech.

Pricing

You can start free, and a pricing page lists the plans.

Who it suits

It suits Twitch streamers who want interactive, monetised viewer alerts with more voice variety and moderation than basic TTS.

Things to consider

Voice clones of real people raise consent and likeness issues; confirm that the official voices are licensed, and avoid custom voices of people who have not agreed. Even with filtering, keep moderators watching the queue, and follow Twitch's rules on viewer-generated content. Set sensible minimums so the stream does not become dominated by alerts.

Because everything is tied to channel events, TTSLabs works as part of the stream's monetisation rather than as a separate voice generator.
