This 3-in-1 extension for SAMMI is all you need for your Text-To-Speech needs!

It supports regular Web Speech API, Google API and Amazon Polly API for text synthesis. That's around 400 different voices and over 50 languages!

Web Speech API

Web Speech API is a completely free and unlimited API for TTS. It contains all voices supported by your Windows and works when running Bridge from within OBS in a dock (only for OBS 27.2 and higher).

Google Cloud Text-to-Speech

Google provides its own TTS service with around 300 voices and 50 languages.  

Google Cloud's free tier lets you use up to 4 million standard or 1 million neural characters per month for completely free. The free usage limit does not expire, but may be subject to change.  

See the up-to-date pricing details at the official Google site.
Google TTS requires a valid credit card to confirm your identity. 

Amazon Polly

Amazon provides a TTS service with around 66 different voices.  
You get a free tier for the first 12 months starting from your first request for speech.  
The free tier includes 5 million standard and 1 million free neural characters per month.

See the up-to-date pricing details at the official AWS site. 
Amazon TTS requires a valid credit card to confirm your identity. 

Playback Controls

You can play, pause, skip and control the volume of your TTS (some commands are not fully supported for the regular Web Speech API).

Voice Settings

You can change the pitch and speed for all TTS services.  
Amazon Polly offers soft and whispered voices.

Random Voice

For each service, you can choose the TTS voice to be completely random! That will make for some funny moments for your viewers for sure!

Automatic Queue

You can easily queue up all your TTS requests and they will be played one by one. This is fully automatic!  

Queue for Polly and Amazon TTS is combined, while Web Speech API has its own separate queue.

SSML Support

Google and Polly TTS voices support custom SSML queries.
