Text-to-speech technology simulates human voices

Text-to-speech technology allows computerized assistants, such as Siri or Alexa, to simulate human-like voices. This process involves software breaking words down into phonemes, which are the smallest building blocks of speech.

To produce sound, a computer sends electrical signals to a speaker that vibrates rapidly, creating sound waves in the surrounding air. This simulates the human biological process where lungs push air through vocal cords to create vibrations, which the brain and mouth then shape into words.
