Text-to-speech
Also TTS
Text-to-speech turns written text into spoken audio.
In practice: Modern AI voices add natural pauses, emphasis and emotion, and many tools offer dozens of voices and languages. They are used for voice-overs, audiobooks, accessibility, video narration and phone systems.
Why it matters when picking a tool
Listen to long samples, not just one sentence, since quality often drops over a few minutes. Check pronunciation of names and technical terms, language coverage, commercial use rights and whether you can adjust pace and tone. Pricing is usually per character or per minute.
