Speech Synthesis (Text-to-Speech / TTS)

Speech synthesis — commonly referred to as Text-to-Speech (TTS) — is the technology that converts written text into spoken audio output. TTS determines how natural, expressive, and human-sounding an AI Agent sounds during a voice conversation. Neural TTS systems, dominant since around 2021, produce speech of near-human quality with natural prosody, appropriate pausing, and emotional nuance — far surpassing earlier robotic outputs. Enterprises can choose from a wide range of voices, configure custom voices to match brand identity, and use SSML markup to control pronunciation, emphasis, and pacing. NiCE Cognigy supports all leading TTS providers and enables custom branded voice personas.

For enterprise teams, Speech Synthesis (Text-to-Speech / TTS) matters because real-world outcomes depend on how the capability is integrated, governed, and measured — not just on the underlying technology. Enterprises can choose from a wide range of voices, configure custom voices to match brand identity, and use SSML markup to control pronunciation, emphasis, and pacing.
