Vois

Product Introduction

1. Definition: Vois is a desktop-based AI voice studio application specializing in 100% offline text-to-speech (TTS) generation and audio production. It operates locally without cloud dependencies.
2. Core Value Proposition: Vois eliminates cloud TTS limitations—per-character fees, privacy risks, and usage caps—by enabling unlimited studio-quality voice generation directly on your device.

Main Features

1. 100% Local Processing:

   • How it works: All voice synthesis occurs on-device via Rust-optimized TTS engines. Scripts, voice data, and audio never leave the machine, leveraging hardware acceleration (e.g., Apple Silicon’s 6x real-time processing).
   • Technologies: Rust-based architecture, Core ML/Metal integration (Apple), DirectML (Windows), and local neural networks for latency-free inference.

2. Voice Cloning & Customization:

   • How it works: Upload 5-60 seconds of audio; Vois trains a voice model locally using speaker diarization and prosody-mapping algorithms. Cloned voices work across all 23 languages.
   • Technologies: PyTorch/TensorFlow Lite for on-device training, adaptive voice transfer learning, and phoneme alignment.

3. Multi-Speaker Production Studio:

   • How it works: Assign 63+ built-in voices (or clones) to speaker tags in scripts. The timeline editor arranges clips with crossfades, while mastering tools apply LUFS normalization, de-essing, and EQ presets.
   • Technologies: Non-destructive audio editing (similar to DAWs), FFmpeg-based export (WAV/MP3/FLAC), and ACX/Spotify-compatible loudness targeting.

4. Polyglot TTS Engines:

   • How it works: Three engines: "Fast" (optimized for speed), "Expressive" (emotional prosody), and "Multilingual" (23 languages per voice). All use local acoustic models.
   • Technologies: Tacotron 2/Flowtron derivatives, grapheme-to-phoneme conversion, and language-agnostic voice embeddings.

Problems Solved

1. Pain Point: Cloud TTS platforms charge per character and upload scripts to third-party servers, increasing costs and privacy risks.
2. Target Audience:
   • Podcasters: Solo creators needing multi-voice episodes.
   • Audiobook Authors: Indie writers converting manuscripts to ACX-compliant audio.
   • YouTube Creators: Faceless channels requiring scalable, consistent voiceovers.
   • Game Devs: Developers generating NPC dialogue locally.
3. Use Cases:
   • Revising script punctuation without re-generation fees.
   • Cloning a voice for multilingual documentary narration.
   • Mastering podcast audio to -16 LUFS in one app.

Unique Advantages

1. Differentiation: Unlike ElevenLabs (cloud-based, per-character billing), Vois offers flat-rate pricing, offline operation, and integrated editing/mastering—replacing Audacity, Descript, and cloud TTS.
2. Key Innovation: Localized voice cloning + multilingual support in a single Rust-native app, achieving 6x real-time speeds on Apple Silicon via hardware optimization.

Frequently Asked Questions (FAQ)

1. Does Vois work without an internet connection?
   Yes, Vois processes all data locally—no internet required after installation.
2. Can I use cloned voices commercially?
   Absolutely. Vois grants full commercial rights to generated audio, including cloned voices.
