SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Local text-to-speech processing with no cloud dependency, enabling privacy-preserving voice synthesis on local devices.

Core Features & Use Cases

  • Offline TTS: synthesize speech from text using sherpa-onnx runtime and models without internet.
  • Cross-platform: works on macOS, Linux, and Windows via a simple wrapper.
  • Model-driven voices: switch voice characteristics by changing the model directory.

Quick Start

Run the sherpa-onnx-tts wrapper with your text input to generate an audio file using your local runtime and model directories.

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 an internet connection?▼

Run offline text-to-speech locally by using the sherpa-onnx runtime and a model directory to synthesize speech from text without any cloud dependency. Configure your environment variables and execute the wrapper to generate audio files on your device.

What prerequisites do I need to set up for offline speech synthesis?▼

Offline speech synthesis requires the sherpa-onnx runtime and a local model directory. You must configure the SHERPA_ONNX_RUNTIME_DIR and SHERPA_ONNX_MODEL_DIR environment variables before generating audio files.

Does the local TTS wrapper support macOS, Linux, and Windows?▼

Yes, the local TTS wrapper supports cross-platform deployment on macOS, Linux, and Windows. It provides a simple wrapper to generate audio files consistently across different operating systems using the sherpa-onnx runtime.

How can I change the voice characteristics for audio file generation?▼

Change voice characteristics by switching the model directory configured in SHERPA_ONNX_MODEL_DIR. The local TTS synthesis is model-driven, allowing you to alter voices by pointing to different sherpa-onnx voice models.

When should I use local TTS instead of cloud-based speech synthesis?▼

Use local TTS for offline voice synthesis on personal devices, enterprise environments, and edge deployments where privacy matters. It avoids cloud dependencies and ensures privacy-preserving speech generation without internet access.
