AI voice generator with 1,000+ realistic voices in 142+ languages
Pick from a large library of expressive voices spanning dozens of languages and accents for video, podcast, audiobook and ad narration.
Generate speech using your own approved voice to keep narration consistent across episodes, courses and brand content.
Arrange scripts into scenes, assign different voices per speaker, regenerate single lines and add pauses or cadence cues without redoing the whole take.
Guide delivery with warm, calm, confident, excited or narrator-style prompts, plus pronunciation controls for names and brand terms.
AI-powered prank calls with a voice you choose
Enter a phone number, select an AI voice and describe the scenario in a prompt — no technical setup or scripting required.
The agent responds in the moment rather than reading a fixed script, so the call plays out differently each time.
Pick which AI voice the caller uses so you can match the character or mood of the prank you have in mind.
The whole workflow runs in a single-page web app, so there is nothing to download or configure.
