內容簡介
總結文案：Speechable 是一個 WordPress 外掛，利用 AI 技術將您的內容轉換成自然聲音的音頻。該外掛使用 Piper TTS，一個在瀏覽器中運行的開源神經文本轉語音引擎。
問題與答案：
1. Speechable 外掛使用了哪些第三方服務來實現文字轉語音功能？
- Piper TTS Web Library（由 Mintplex Labs 提供）
- Whisper（由 Hugging Face Transformers.js 提供）
2. 在使用 Speechable 外掛時，哪些資料會被傳輸？
- 在生成音頻時，TTS程式庫和ONNX運行時庫會從CDN加載
- 當首次使用某種語音時，語音模型文件將從Hugging Face下載
- Whisper模型僅在第一次使用時用於單詞時間戳提取
- 您的內容文本在本地瀏覽器中進行處理，不會發送到任何外部服務器
3. 為什麼 Speechable 外掛需要外部資源？
- 文本轉語音引擎需要機器學習運行時（ONNX）和過大的語音模型，無法捆綁到插件中。這些資源按需從CDN服務加載，類似Google字體或其他網絡服務的工作方式。這種基於服務的方法使得插件輕量化，同時提供高質量的AI語音。
原文外掛簡介
Speechable transforms your WordPress content into natural-sounding audio using AI-powered text-to-speech technology. Speechable uses Piper TTS, an open-source neural text-to-speech engine that runs in your browser.
Third-Party Service
This plugin uses the following third-party services for text-to-speech functionality:
Piper TTS Web Library
Service Provider: Mintplex Labs
Library CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@mintplex-labs/piper-tts-web)
ONNX Runtime CDN: Cloudflare (https://cdnjs.cloudflare.com/ajax/libs/onnxruntime-web)
WASM Phonemizer CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@diffusionstudio/piper-wasm)
Voice Models: Downloaded from Hugging Face
Terms of Service: MIT License
Whisper (Word Timestamps)
Service Provider: Hugging Face Transformers.js
Library CDN: jsDelivr (https://cdn.jsdelivr.net/npm/@huggingface/transformers)
Model: Xenova/whisper-tiny.en (~75MB, downloaded on first use)
Purpose: Provides accurate word-level timestamps for synchronized highlighting
Terms of Service: Apache 2.0 License
What data is transmitted:
The TTS library and ONNX runtime are loaded from CDN when generating audio
Voice model files are downloaded from Hugging Face when first using a voice
Whisper model is downloaded for word timestamp extraction (first use only)
Your content text is processed locally in your browser and is NOT sent to any external server
Once downloaded, all resources are cached locally in your browser
Why external resources are required:
The text-to-speech engine requires machine learning runtime (ONNX) and voice models that are too large to bundle with the plugin. These are loaded on-demand from CDN services, similar to how Google Fonts or other web services work. This is a service-based approach that keeps the plugin lightweight while providing high-quality AI voices.

Tips for Best Results
Use High quality for important content where word sync matters
Preview voices in Settings before generating to find the best match
Shorter posts generate faster – consider breaking very long content into parts
First generation takes longer as voice models are downloaded and cached
Word highlighting works best with standard theme content areas
