say plugin for MADS

This is a Sink plugin for MADS.

This is a sink agent that speaks any string received on in the "tts" field in the JSON input message. The plugin uses the espeak library to generate the speech.

This plugin has been updated for MADS v2

• Linux

Dependencies

On Linux, the plugin requires the espeak library. To install it, run:

sudo apt-get install espeak libespeak-dev

Translation/I18N

The plugin supports translation of the spoken text. The translation is done using a dictionary file that maps the original text to the translated text. The dictionary file is a JSON file with the following format:

{
    "original text": {
        "it": "testo tradotto",
        "fr": "texte traduit",
        "es": "texto traducido"
    }
}

If the translated text is not found in the dictionary, the original text is spoken.

This JSON file must be installed in the fordel share/translate under the MADS installation directory.

INI settings

The plugin supports the following settings in the INI file:

[say]
language = "europe/it" # Must be a valid espeak language code
locale = "it"          # Used for lanuage translation
dictionary = "translations.json" # Name of translation dictionary

All settings are optional; if omitted, the default values are used.

Executable demo

The demo executable joins all its arguments as a single string and speaks them.
