sherpa-onnx-tts

Offline text-to-speech synthesis runs locally using the sherpa-onnx runtime and models. It generates speech on-device without cloud services, ensuring privacy-preserving audio generation without network dependencies or external API calls.

Yes, you can use local TTS across multiple operating systems including macOS, Linux, and Windows. The setup involves configuring environment variables to define runtime and model directories for each platform-specific environment.

Setup involves installing the sherpa-onnx runtime and downloading required models, then configuring environment variables to specify runtime and model directories. Once configured, run the wrapper to generate speech locally.

No, offline TTS does not require an internet connection to generate audio. Once the sherpa-onnx runtime and models are downloaded and installed, all speech synthesis runs entirely on-device without cloud connectivity.

Use on-device speech synthesis for personal assistants and embedded systems requiring offline TTS capabilities. It is ideal when privacy-preserving audio generation is needed without cloud dependencies or external network connectivity.

Offline local TTS models require sufficient storage for the sherpa-onnx runtime and model files. Performance depends entirely on the host device hardware since all speech synthesis processing occurs locally without cloud-based acceleration.
