sherpa-onnx-tts

To convert text to speech locally without a cloud network dependency, you can use the offline sherpa-onnx runtime to process text and generate audio files entirely on your device without sending data to external servers.

Offline TTS with sherpa-onnx supports cross-platform environments including Windows, Linux, and macOS, allowing you to build on-device assistants or accessibility tools across different operating systems.

To configure sherpa-onnx text-to-speech, you must specify a runtime directory and a model directory, which validates required files and enforces environment path configurations to perform audio generation successfully.

The best way to build an on-device assistant that reads text aloud offline is using local text-to-speech processing with sherpa-onnx, which handles voice output generation without requiring cloud services.

For local text-to-speech processing, you need optional voice models placed in a designated model directory, as the sherpa-onnx runtime requires these paths to validate files and execute TTS generation.
