In today’s world, people communicate in more than one languages. The most common way to communicate is through speech. We all need to be able to speak in order to be able to understand each other. Unfortunately, not everyone has the ability to speak in their own language. In order to make it easier for them to communicate, they use text-to-speech (TTS) systems. These systems allow them to generate speech and then hear it as audio.

The OpenTX Speech app is a TTS system that allows you to generate speech in the language of your choice. You can use any of the built-in voices or generate your own voice.

The first step is to select the desired voice from the list that is provided by the app.

After that, you need to select "User Defined Lists".
