| Summary | k2-fsa is an open-source speech AI toolkit — often described as a next-generation Kaldi — providing libraries and tools for building, training, decoding, and deploying speech systems including ASR, TTS, VAD, and speaker identification. Its core library brings finite-state automaton/transducer (FSA/FST) algorithms into PyTorch-compatible autograd workflows. | Aider is an open-source AI pair-programming tool that runs in the terminal and edits code directly in a local Git repository through natural-language chat with an LLM. It automatically commits changes and supports a wide range of hosted and local models. |
