We built VoiceNPC with a simple idea: your voice data (and your script) should never leave your device.
Other voice cloning services charge $22-99/month, limit your usage with credits, and process your voice (and your script) on their servers. We do things differently.

Yes, new in version 1.3. Type your script in any supported language, pick one or more target languages, and your cloned voice will speak the translation. Tap Preview first to read and edit each translated section before generating, so you can catch any mistranslations. Free users translate to one language at a time; Pro users select multiple at once.
Yes. Translation uses Apple's on-device Translation framework, so your script never leaves the device. Most other voice cloning services either don't offer translation or send your text through a cloud API. VoiceNPC keeps both the translation and the voice synthesis fully local.
A Pro feature. Select multiple target languages in a single pass and VoiceNPC generates a separate audio file for each, all in your cloned voice. Perfect for content creators publishing the same script as a podcast, video voiceover, or app demo across many locales without repeating the prompt cycle.
VoiceNPC runs entirely on your device, including the new in-app translation. Your voice and your script never touch a server. Most cloud services charge $22-99/month with strict character or minute limits, and process your data on their servers. VoiceNPC Pro is $2.99/month with truly unlimited usage.
Never. All voice cloning, translation, and text-to-speech processing happens locally on your Apple Silicon chip using the Qwen3-TTS model and Apple's frameworks. Zero network requests are made during voice cloning, translation, or speech generation. Your voice fingerprints are stored only in the app's local sandbox.
Projects let you create multi-section audio with different voices and languages in each section. Perfect for podcasts with multiple speakers, audiobook chapters with distinct character voices, video dubbing in several languages, or any dialogue-style content. Use the rich editor to add sections visually, or write markup in source mode.
Unlike services that advertise 'unlimited' but enforce fair-use caps or credit systems, VoiceNPC Pro has no character limits, no minute caps, and no credits that expire. Generate as much speech as you want, as often as you want, in as many languages as you want.
No. Voice cloning, translation, and speech generation work completely offline. You only need internet for the initial app download, model setup, and the one-time language pack downloads for translation (handled by iOS in the background).
