Offline text-to-speech synthesis converts text strings into audio files entirely on your local machine, ensuring privacy by operating without external network dependencies or cloud services.

Local text-to-speech generation requires pre-downloaded runtime and model directories. You must configure these paths using the SHERPA_ONNX_RUNTIME_DIR and SHERPA_ONNX_MODEL_DIR environment variables before execution.

Yes, offline audio generation supports customizable voices. You can supply and apply various pre-downloaded voice models to the engine to generate different speech outputs for your local files.

Yes, offline TTS functions entirely without an internet connection, relying strictly on the local sherpa-onnx engine to synthesize speech, which ensures privacy and accessibility for sensitive applications.

To create a wav file from text, use the local TTS engine to synthesize the input string and directly output the resulting speech audio into a named .wav file on your machine.

Offline text-to-speech is used instead of cloud APIs when absolute privacy is required, eliminating external dependencies and ensuring accessibility for applications generating speech without sending data over the network.
