Text-to-Speech
Text-to-speech (TTS) is the technology that converts written text into natural-sounding spoken audio, enabling AI systems to communicate with customers through voice channels.
In Depth
Text-to-speech is the output side of voice AI — it gives AI agents a voice. Modern TTS systems produce remarkably natural speech that is often indistinguishable from human voices. They support multiple languages, accents, speaking styles, and emotional tones.
In customer support, TTS powers voicebots and IVR systems, enables AI agents to handle phone calls autonomously, and provides accessibility for visually impaired customers. Advanced TTS allows customization of voice characteristics (pitch, speed, warmth) to match brand personality, dynamic adjustment of tone based on conversation context (more empathetic when a customer is upset), and seamless switching between languages in multilingual support environments. The quality of TTS directly impacts customer perception — robotic-sounding voices erode trust, while natural voices increase engagement and satisfaction.
