+
+# 🎹 "Powerset" speaker segmentation
+
+This model ingests 10 seconds of mono audio sampled at 16kHz and outputs speaker diarization as a (num_frames, num_classes) matrix where the 7 classes are _non-speech_, _speaker #1_, _speaker #2_, _speaker #3_, _speakers #1 and #2_, _speakers #1 and #3_, and _speakers #2 and #3_.
+
+![Example output](example.png)
+
+```python
+# waveform (first row)
+duration, sample_rate, num_channels = 10, 16000, 1
+waveform = torch.randn(batch_size, num_channels, duration * sample_rate) 
+
+# powerset multi-class encoding (second row)
+powerset_encoding = model(waveform)
+
+# multi-label encoding (third row)
+from pyannote.audio.utils.powerset import Powerset
+max_speakers_per_chunk, max_speakers_per_frame = 3, 2
+to_multilabel = Powerset(
+    max_speakers_per_chunk, 
+    max_speakers_per_frame).to_multilabel
+multilabel_encoding = to_multilabel(powerset_encoding)
+```
+
+The various concepts behind this model are described in details in this [paper](https://www.isca-speech.org/archive/interspeech_2023/plaquet23_interspeech.html).
+
+It has been trained by Séverin Baroudi with [pyannote.audio](https://github.com/pyannote/pyannote-audio) `3.0.0` using the combination of the training sets of AISHELL, AliMeeting, AMI, AVA-AVD, DIHARD, Ego4D, MSDWild, REPERE, and VoxConverse.
+
+This [companion repository](https://github.com/FrenchKrab/IS2023-powerset-diarization/) by [Alexis Plaquet](https://frenchkrab.github.io/) also provides instructions on how to train or finetune such a model on your own data.
+
+## Requirements
+
+1. Install [`pyannote.audio`](https://github.com/pyannote/pyannote-audio) `3.0` with `pip install pyannote.audio`
+2. Accept [`pyannote/segmentation-3.0`](https://hf.co/pyannote/segmentation-3.0) user conditions
+3. Create access token at [`hf.co/settings/tokens`](https://hf.co/settings/tokens).
+
+
+## Usage
+
+```python
+# instantiate the model
+from pyannote.audio import Model
+model = Model.from_pretrained(
+  "pyannote/segmentation-3.0", 
+  use_auth_token="HUGGINGFACE_ACCESS_TOKEN_GOES_HERE")
+```
+
+### Speaker diarization
+
+This model cannot be used to perform speaker diarization of full recordings on its own (it only processes 10s chunks). 
+
+See [pyannote/speaker-diarization-3.0](https://hf.co/pyannote/speaker-diarization-3.0) pipeline that uses an additional speaker embedding model to perform full recording speaker diarization.
+
+### Voice activity detection
+
+```python
+from pyannote.audio.pipelines import VoiceActivityDetection
+pipeline = VoiceActivityDetection(segmentation=model)
+HYPER_PARAMETERS = {
+  # remove speech regions shorter than that many seconds.
+  "min_duration_on": 0.0,
+  # fill non-speech regions shorter than that many seconds.
+  "min_duration_off": 0.0
+}
+pipeline.instantiate(HYPER_PARAMETERS)
+vad = pipeline("audio.wav")
+# `vad` is a pyannote.core.Annotation instance containing speech regions
+```
+
+### Overlapped speech detection
+
+```python
+from pyannote.audio.pipelines import OverlappedSpeechDetection
+pipeline = OverlappedSpeechDetection(segmentation=model)
+HYPER_PARAMETERS = {
+  # remove overlapped speech regions shorter than that many seconds.
+  "min_duration_on": 0.0,
+  # fill non-overlapped speech regions shorter than that many seconds.
+  "min_duration_off": 0.0
+}
+pipeline.instantiate(HYPER_PARAMETERS)
+osd = pipeline("audio.wav")
+# `osd` is a pyannote.core.Annotation instance containing overlapped speech regions
+```
