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

Offline text-to-speech synthesis runs locally by leveraging an ONNX-based model to convert text input into speech, ensuring no network access is required. This approach enhances user privacy and is suitable for air-gapped systems.

What is local speech synthesis using ONNX models and when is it needed?

Local speech synthesis using ONNX models generates audio directly on your hardware from text. It is needed in environments where network access is restricted or unavailable, such as embedded systems and home automation scenarios.

Do I need a specific binary and voice model to synthesize speech locally?

Yes, to synthesize speech locally you need the Piper binary and an ONNX voice model. These components process your text input on-device to generate audio without relying on external network calls.

Can I use custom ONNX voice models for different languages in offline TTS?

Yes, offline TTS supports custom ONNX voice models for various languages and quality levels. You can load specific models into your local environment to synthesize speech in your preferred language.

Is offline speech synthesis suitable for embedded hardware and home automation?

Offline speech synthesis is ideal for embedded hardware and home automation because it processes text locally without network connectivity. This ensures reliable operation in restricted or air-gapped environments.
