FAQPage Schema
How do I run offline text-to-speech synthesis on-device without an internet connection?

Offline text-to-speech synthesis runs directly on your device using the sherpa-onnx runtime and ONNX models. It converts text to spoken audio locally without sending data to cloud services, ensuring privacy and network independence.

What do I need to set up before running local TTS with sherpa-onnx?

Local TTS with sherpa-onnx requires setting the SHERPA_ONNX_RUNTIME_DIR and SHERPA_ONNX_MODEL_DIR environment variables. You also need a model directory containing the ONNX model file, tokens, and data files for voice synthesis.

Can I use sherpa-onnx TTS for privacy-preserving voice assistants and accessibility tools?

Yes, sherpa-onnx TTS supports privacy-preserving voice assistants and accessibility tools. It generates speech entirely on-device, ensuring no user data or text leaves the local machine during the voice synthesis process.

Does on-device voice synthesis work without cloud services for assistive reading?

On-device voice synthesis works completely offline for assistive reading without relying on cloud services. The local sherpa-onnx engine handles the text-to-speech conversion independently, guaranteeing functionality during network outages.

What are the limitations of offline TTS compared to cloud-based speech synthesis?

Offline TTS requires local storage for model files and manual environment configuration. Unlike cloud-based speech synthesis, you must manage the ONNX runtime installation and model directory setup yourself to ensure proper voice generation.
