Alongside k2, it is a part of the next generation Kaldi speech processing library. Tutorial presentations and materials - ( Interspeech 2023 ) Tutorial notebook - ( Interspeech 2023 ) Tutorial slides - ( Interspeech 2021 ) Recorded lecture (3h) About Main goals (updated for 2025) - Scale to multimodal data pipelines including audio, text, image, and video modalities. - Provide state-of-the-art dataloading algorithms such as dataset blending and efficient on-the-fly bucketing. - Handle data randomization (or de-duplication) for distributed multi-node training. - Attract a wider community to multimodal processing tasks with a Python-centric design . - Provide standard data preparation recipes for commonly used corpora. - Flexible data preparation for model training with the notion of audio/video cuts . - Support for efficient sequential I/O data formats such as Lhotse Shar (similar to webdataset). Tutorials We offer the following tutorials available in examples directory: - Basic complete Lhotse workflow - Transforming data with Cuts - WebDataset integration - How to combine multiple datasets - Lhotse Shar: storage format optimized for sequential I/O and modularity - Image and Video Support in Lhotse Examples of use Check out the following links to see how Lhotse is being put to use: - Icefall recipes: where k2 and Lhotse","default_branch":null,"files":null,"tree":[],"storefront":"/r/lhotse-speech","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/lhotse-speech/lhotse/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
