Text to Speech
Text to speech, or TTS, is technology that converts written text into spoken audio. Modern neural TTS generates natural-sounding voices with realistic intonation, rhythm and emotion rather than the robotic output of older systems.
Older TTS systems stitched together pre-recorded sound fragments, which is why they sounded mechanical. Neural TTS instead generates the audio waveform directly with a model that has learned how humans actually speak: where we pause, which words we stress, how a question rises at the end. The result is speech that carries meaning, not just pronunciation.
Getting natural narration is mostly about writing for the ear. Punctuation drives pacing, so commas and full stops create pauses where a human would breathe. Short sentences read better than long ones. Spelling out numbers, acronyms and unusual names the way they should sound prevents most mispronunciations.
Voice choice matters as much as the text. A voice that suits a documentary will feel wrong on an energetic product ad. Good TTS platforms offer a range of voices and often controls for speed and delivery, and many pair TTS with voice cloning so you can use a specific real voice instead of a stock one.
TTS is the workhorse behind video voiceovers, audiobooks, e-learning, accessibility features and AI avatars. On Arteza, the audio studio hosts TTS models including ElevenLabs voices, and the output can feed directly into lip synced avatar videos.
Frequently asked questions
How do I make text to speech sound more natural?
Write conversationally, keep sentences short, use punctuation to control pauses, and spell out anything ambiguous the way it should be spoken. Then pick a voice whose tone matches the content.
Can I use TTS audio commercially?
Usually yes, subject to the platform's license. Audio you generate in the Arteza audio studio is yours to use in your projects, including commercial ones.
What is the difference between TTS and voice cloning?
TTS speaks in stock or designed voices. Voice cloning captures a specific person's voice from a sample and then uses TTS to generate speech in that exact voice.
