Text-to-Speech

Text-to-speech (TTS) converts written text into spoken audio. Early TTS systems sounded robotic and mechanical; modern AI-based TTS models generate voices that are close to indistinguishable from human speech, with natural pacing, emotion, and intonation. TTS is used for video voiceovers, audiobooks, podcast production, IVR phone systems, accessibility tools, and dubbing content into other languages.

As more brand content gets consumed as audio — voiceovers on short-form video, AI-narrated articles, multilingual dubbing — the quality of the voice behind it affects how professional and trustworthy that content feels. It's also an efficient way to repurpose existing written content (like a glossary or blog) into a new format without hiring voice talent for every piece.

A common example is turning a written blog post into a narrated audio version, or dubbing a product demo video into multiple languages without re-recording. ElevenLabs is one of the most widely used AI voice platforms for this, offering realistic TTS, voice cloning, and multilingual dubbing.
