Frequently Asked Questions about sherpa-onnx-tts

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run text-to-speech locally without cloud services?▼

Offline local TTS is achieved by running the sherpa-onnx runtime to synthesize speech directly on your device. This approach bypasses cloud services, requiring only local environment variables and a pre-trained voice model.

Does offline TTS work on macOS, Linux, and Windows?▼

Yes, offline TTS with sherpa-onnx supports macOS, Linux, and Windows. The setup includes install steps to download the runtime and a Piper en_US lessac model for multiplatform compatibility.

What do I need to set up before synthesizing speech with sherpa-onnx?▼

Before synthesizing speech, you need to set the SHERPA_ONNX_RUNTIME_DIR and SHERPA_ONNX_MODEL_DIR environment variables. The install steps automatically download the required sherpa-onnx runtime and Piper voice model.

When should I use local voice synthesis instead of cloud TTS?▼

Use local voice synthesis in privacy-sensitive environments or embedded-device workflows where cloud services are unavailable or undesirable. It provides private voice output for desktop or embedded devices without network access.

Can I use pre-trained voice models for offline text-to-speech?▼

Yes, offline TTS using sherpa-onnx supports pre-trained voice models. The setup includes downloading a Piper en_US lessac model to synthesize speech locally without requiring network connectivity.
