Generate speech locally by using the offline text-to-speech engine to synthesize voice without an internet connection. This engine processes pre-downloaded voice models on your machine, outputting audio files like tts.wav directly to your local storage.

Configure the local TTS environment by setting the SHERPA_ONNX_RUNTIME_DIR and SHERPA_ONNX_MODEL_DIR environment variables. These variables point the engine to the pre-downloaded runtime and voice model assets required to initialize synthesis.

Offline text-to-speech generation does not require uploading sensitive text to the cloud. The synthesis process runs entirely on your local machine, ensuring privacy and zero cloud dependency for your voice generation applications.

The best way to create local voiceovers without cloud APIs is using a local offline text-to-speech solution. It directly converts your text scripts into audio files locally, reducing latency and keeping sensitive presentation content private.

You can use different voice models for local speech synthesis by loading various pre-downloaded voice assets. This customizable voice support allows you to generate different speech outputs from the same offline text-to-speech engine.

Choose local TTS over cloud-based voice generation services when your application requires strict privacy, reduced audio latency, and no cloud dependency. It guarantees availability without an internet connection by processing voice models directly on your machine.
