gryannote is a collection of Gradio custom components focusing on the labeling of speaker diarization data. Integrated with the pyannote speaker diarization ecosystem, it allows to build web applications to load pretrained pyannote pipelines and customize their hyper-parameters, upload or record an audio file, process it with the pipeline, visualize and interact with its outputs, correct them if needed, and export the final annotation in RTTM format. Each of these components can be used independently from each other.
