Definition
A technology that converts written text into synthesized spoken audio, used by creators for accessibility features, automated narration, live stream chat readers, and AI-generated voiceovers. TTS tools range from basic robotic synthesizers to advanced neural voice models that closely replicate human speech patterns, intonation, and emotion. In live streaming, TTS is commonly used to read viewer chat messages aloud, enabling streamers to respond to their audience without looking away from their content. In content production, TTS enables creators to produce audio content without recording their own voice.
