Speak Response
You can make a prototype "speak" by reading a text, either as-is or via a formula, out loud.
Text
You can enter the text to be read out loud.

For example, once you tap the logo, the prototype would speak: "ProtoPie is the most intuitive way to prototype and perfect them".
Formula
To make your voice interaction more dynamic, you can use formulas as long as the used formula results in a text. Also, you can use the predefined variable $voiceTranscript that stores the last voice command.
Voice Options
You can customize the voice used by choosing a language, type of voice, speed, and pitch.
Language
You can choose from 40 languages and language variants.
Voiced by
You can choose between a female and male voice per language.
Speed
You can adjust the speed by choosing a value between 0.5 and 2.
Pitch
You can adjust the pitch by choosing a value between 0.5 and 2.

For example, once listening is enabled, the prototype would "speak" back to you by reading out loud whatever your incoming voice command was.
