What is Piper TTS?

Piper is a high-speed, localized neural text-to-speech (TTS) system specifically designed for devices such as the Raspberry Pi 4, with the goal of delivering exceptional speech synthesis capabilities independent of cloud services. By utilizing neural network models created with VITS and later converted to ONNX Runtime, it ensures both efficient and lifelike speech generation. The system supports a wide range of languages including English (US and UK variations), Spanish (from Spain and Mexico), French, German, and several others, along with options for downloadable voices. Users can interact with Piper through command-line interfaces or easily incorporate it into Python applications using the piper-tts package, allowing for versatile usage. Features like real-time audio streaming, the ability to process JSON inputs for batch tasks, and support for multi-speaker models further enhance its functionality. In addition, Piper leverages espeak-ng for phoneme generation, converting text into phonemes prior to speech synthesis. Its versatility is evident in its applications across multiple projects such as Home Assistant, Rhasspy 3, and NVDA, showcasing its adaptability to various platforms and scenarios. By prioritizing local processing, Piper is particularly appealing to users who value privacy and efficiency in their speech synthesis applications. Its capability to operate seamlessly across different environments makes it a powerful tool for developers and users alike.
