VoiceNPC: AI Voice Clone

Try Pro free for 7 days: unlimited generations, no ads, cancel anytime. Clone a voice on your iPhone and hear it speak 10+ languages, all on-device and offline.

Record 5 seconds of a voice. Clone it. Type anything and hear it spoken back in 10+ languages, with translation built in. Cloning, speech and translation all run on your device, so your recordings, your text and the audio you make never leave it.

VoiceNPC runs the Qwen3-TTS model locally through Apple's MLX framework. From a short recording it builds a voice fingerprint, then speaks whatever you type in that voice.

Works on iPhone, iPad, and Mac with Apple Silicon.

What you can do:

• Start with 8 built-in voices, no recording needed
• Clone any voice from a 5–15 second recording, or import one from a video
• Generate speech in English, Chinese, Japanese, Korean, French, German, Spanish, Russian, Italian, Portuguese, and more
• Translate your text on-device and have your cloned voice read it out in another language
• Pro: pick multiple target languages and generate them all in a single pass
• Preview and edit a translation before you generate the audio
• Pro: create multi-voice projects and give each section its own voice and language, for dialogue, audiobooks, and podcasts
• Choose a style preset (Stable, Natural, Expressive), or adjust the settings yourself
• Export as WAV, or share a voice fingerprint (a .voicenpc file) over AirDrop, Messages, or any app, so others can generate speech in your voice
• Clone as many voices as you like, on the free plan too

Built for creators:

• YouTubers: dub your videos in several languages in your own voice, with no separate translation step
• Podcasters: produce multi-speaker episodes without extra recording sessions
• Audiobook narrators: give every character its own voice
• Voiceover artists: share your voice fingerprint with clients so they can generate lines on demand
• Game developers: generate NPC dialogue in every language you ship

Why it's different:

• Cloning, speech and translation run on-device, and keep working offline after install
• Your recordings and the text you type stay in the app's sandbox, never uploaded
• No cloud processing: your voice never touches a server
• Apple Silicon does the work: the model runs on the chip in your iPhone, iPad, or Mac

How energy works:

• 1 energy ≈ 100 characters of text, about 1–2 sentences
• 25 energy every day, enough for about 5 full generations
• Watch a short video for 25 bonus energy (up to 5 videos a day)
• Earn extra energy by sharing the app daily or inviting friends with your code
• Pro subscribers get unlimited generations with no ads

Go Pro:

• Unlimited generations and no ads, plus multi-language runs and multi-voice projects
• Choose a monthly, annual, or one-time lifetime plan

Requires iPhone 13 or later, iPad mini (6th gen) or later, iPad Air (5th gen) or later, iPad (11th gen) or later, or any Apple Silicon Mac.
