What is Voice Synthesis?
Voice synthesis is the artificial production of human speech using computer algorithms. Unlike traditional recording, which captures a real person’s voice, voice synthesis leverages advanced models—such as deep learning neural networks—to generate speech from text. Modern voice synthesis can produce voices that are nearly indistinguishable from human speakers, offering:
- Natural intonation and emotion
- Multiple voice styles and accents
- Customizable speed and pitch
- Support for dozens of languages
In podcasting, voice synthesis unlocks creative possibilities, from multilingual episodes to unique AI co-hosts and seamless script narration.
