FreePBX AWS Polly TTS Engine

About

This is a FreePBX TTS Engine for AWS Polly. It is based on the FreePBX TTS Engine from The Web Machine. I updated the code to work with the aws sdk v3 (as v2 is no longer supported), packaged it with a 'new' version of nodejs (16) and added some new features.

Just want to use it?

See the step-by-step guide in the wiki.

Features

• AWS Polly TTS Engine
• Multi Language Support
• Multi Voice Support
• Prefix and Suffix Support

Installation

For beginners: see the step-by-step guide in the wiki.

Login to your FreePBX Server and run the following command:

curl -s https://raw.githubusercontent.com/scolastico/freepbx-aws-polly/main/install.sh | bash

Configuration

After the installation you can configure the /opt/scolastico/freepbx-aws-polly/config.json file.

See the defaultConfig.json for reference.

You can find the available voices here.

You should create a IAM user with the following permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1234567890",
            "Effect": "Allow",
            "Action": [
                "polly:SynthesizeSpeech"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

FreePBX Configuration

After the installation you can configure the TTS Engine in the FreePBX GUI.

Settings -> Text to Speech Engines -> Add TTS Engine

Engine name: polly Engine path: /opt/scolastico/freepbx-aws-polly/bin

Usage

If you want to use a different voice or language you can use a !<presets as csv> before your text. You can chain multiple presets which will overwrite already set variables For example:

!en Hello World!

or

!de,2-seconds-silence Hello World!

Troubleshooting

If something does not seem to work, check the log files:

tail -f /opt/scolastico/freepbx-aws-polly/logs/combined.log

If this does not help, you are always welcome to open an issue.

Update

Just run the installation again.

Development

You need to install the following packages:

sudo apt install nodejs npm lame

Then install the dependencies:

pnpm install
