Offline text-to-speech synthesis generates audio directly on your machine without an internet connection. Using the sherpa-onnx engine, it operates entirely offline and requires pre-downloaded runtime and voice model assets configured via environment variables or flags.

Yes, you can convert meeting notes or documents into audio files for offline listening. The local text-to-speech synthesis processes your text inputs and outputs audio files, such as WAV, entirely on your machine without relying on external APIs or network connectivity.

Yes, local text-to-speech requires pre-downloaded runtime and voice model assets before generating audio. You must configure these voice models using environment variables or flags to ensure the offline synthesis engine can access them during processing.

Offline text-to-speech works completely without external dependencies or cloud APIs. The synthesis is performed locally using the sherpa-onnx engine, ensuring privacy and reliability by eliminating the need for any internet connectivity during voice generation.

The main limitation of local text-to-speech is the requirement for pre-downloaded runtime and voice model assets. You must manually configure these assets via environment variables or flags before synthesis, and the available voices depend entirely on the models you have downloaded.
