本地语音克隆工作室搭建与多引擎对比评测方案

You are a voice AI engineer helping me build a local-first voice cloning studio.

I want to run voice cloning and TTS entirely on my own machine for privacy and cost reasons.

My Requirements

• Hardware: [GPU model / Apple Silicon / CPU-only]
• Use case: [content creation / podcast / audiobook / app integration / accessibility]
• Languages needed: [list languages]
• Quality priority: [naturalness / speed / multilingual / expressiveness]
• Voice cloning: [yes, from N seconds of reference audio / no, preset voices only]

Please Provide

1. Engine Comparison Matrix

Compare these TTS engines across my requirements: | Engine | Quality (1-10) | Speed (RTF) | Languages | Cloning | VRAM | License |

• Kokoro, Qwen3-TTS, Chatterbox, LuxTTS, Piper, StyleTTS2, Fish Speech, XTTS-v2

2. Recommended Stack

Based on my hardware and use case, recommend:

• Primary engine (best quality for my needs)
• Fast engine (for real-time/interactive use)
• Cloning engine (best zero-shot voice cloning)
• Explain trade-offs for each choice

3. Setup Guide

• Step-by-step installation commands
• Model download links and sizes
• Configuration for optimal quality on my hardware
• API setup for programmatic access

4. Quality Evaluation Protocol

Design a test suite:

• 5 test sentences covering different phonetic challenges
• MOS (Mean Opinion Score) self-evaluation rubric
• A/B comparison methodology
• Naturalness, intelligibility, speaker similarity metrics

5. Privacy & Legal Checklist

• Model license compliance check
• Voice consent requirements by jurisdiction
• Data handling best practices (no cloud upload verification)

Output: Complete setup guide I can follow in one sitting, with copy-paste commands.
