What is paddlespeech?

PaddleSpeech is an open-source toolkit from Baidu's PaddlePaddle team that bundles a wide range of audio and speech tasks into one Python library. It covers converting spoken audio into text (speech recognition), converting text into spoken audio (text-to-speech), identifying who is speaking (speaker verification), detecting specific keywords in audio streams, and translating spoken language from one language to another. The library supports both English and Chinese, including Mandarin, Cantonese, and several other Chinese dialects. For non-developers, PaddleSpeech is most easily accessed through a command-line interface or a server mode, where you can send audio files or text and receive results without writing code. There is also a streaming mode suitable for real-time applications like live transcription or interactive voice systems. The project won a Best Demo Award at a major academic conference in 2022. For developers, the library provides pre-trained models that can be used directly, as well as the underlying training code for those who want to build or fine-tune their own models. A Chinese text processing pipeline handles converting written Chinese numbers, dates, and abbreviations into a form suitable for speech synthesis, which is a detail that matters a lot for natural-sounding Chinese audio output. Installation is through pip, the standard Python package manager, and the toolkit runs on Linux, Windows, and macOS with Python 3.8 or newer. The project is open-source under the Apache 2.0 license.
