TTSAAS

Text To Speech As A Service

Dependencies

Be sure to install the following go libraries:

go get github.com/hegedustibor/htgo-tts
go get github.com/kennygrant/sanitize

Also, the htgo-tts package requires mplayer to be installed, or it will throw an error.

sudo apt install mplayer

Finally, we need ffmpeg to increase the volume

sudo apt install ffmpeg

Usage

Setup

You might need to create a folder named audio in the directory of the executable.

Running

Start the project with go run main.go or build and run the executable.

Choosing a port

The service uses port 80 by default, but this can be configured by setting the TTSAAS_PORT environment variable.

API usage

Navigating to localhost:8000/hello%20world will return an mp3 file with "Hello world" spoken out. The content type is audio/mpeg.

HTML audio element example

The api can be used as a source for audio tags. For example:

<audio controls>
  <source src="http://localhost/hello%20world" type="audio/mpeg">
</audio>
