  • [WIP] Multilabel Detection

    [WIP] Multilabel Detection

    This is a new PR for the VTC feature, this time based on a cleaner implem. I'm making a new PR as to keep the former branch "clean" (and prevent any mishaps).

    What is done:

    • renaming the SpeakerTracking task into a MultilabelDetection task
    • added MultilabelPipeline
    • update MultilabelFscore.report()
    • tested the new preprocessor

    What's to be done:

    • [ ] re-test the new implem on our clinical data (as well as the child data from @MarvinLvn )
    • [ ] maybe a couple of unit tests (especially for the preprocessor)
    • [ ] maybe make the aggregated "multilabel" fscore duration-based instead of file-based

  • Trying the diarization pipeline on random .wav files

    Trying the diarization pipeline on random .wav files

    Hey, as suggested by the detailed tutorials, i went through them and trained all the models required for the pipeline. The pipeline is working on the AMI dataset but when i try to reproduce the results on other .wav files sampled at 16k, mono, and 256bps, it is not able to diarize the audio. Here is the breif of what i actually did.

    1. Took a random meeting audio file, sampled at 16k , mono and 256bps
    2. renamed it to ES2003a and replaced it with actual ES2003a ( thought it as a turnaround of creating another database )
    3. ran all the pipelines ( sad,scd, emb, diarization )

    Output :

    1. Speaker activity detection works perfectly and is able to classify regions of speech.
    2. Speaker diarization does't works, everything is classified as 0

    can you please tell if its because of replacing the actual file that the pipeline is giving wrong outputs for the diarization, and whats a better way to test the pipeline on random audios.

  • Add support for file handle to pyannote.audio.core.io.Audio

    Add support for file handle to pyannote.audio.core.io.Audio

    This is not currently supported:

    from pyannote.audio.core.io import Audio
    from pyannote.core import Segment
    audio = Audio()
    with open('file.wav', 'rb') as f:
        waveform, sample_rate = audio(f)
    with open('file.wav', 'rb') as f:
        waveform, sample_rate = audio.crop(f, Segment(10, 20))
    

    One has to do this instead:

    from pyannote.audio.core.io import Audio
    from pyannote.core import Segment
    audio = Audio()
    waveform, sample_rate = audio('file.wav')
    waveform, sample_rate = audio.crop('file.wav', Segment(10, 20))
    

    This is a limitation that might be problematic (e.g. with streamlit.file_uploader that returns a file handle)

    Describe the bug I'm trying to go through the diarization pipeline tutorial on my own data.

    I am trying to run "apply" on my own data and model for speaker change detection. I get an error that looks like it's trying to apply speech activity detection

  • Trying to finetune model for new speaker

    Trying to finetune model for new speaker

    I am trying to finetune models to support one more speaker, but it looks I am doing something wrong.

    I want to use "dia_hard" pipeline, so I need to finetune models: {sad_dihard, scd_dihard, emb_voxceleb}.

    For my speaker I have one WAV file with duration more then 1 hour.

    So, I created database.yml file:

    Databases:
       IK: /content/fine/kirilov/{uri}.wav
    
    Protocols:
        IK:
           SpeakerDiarization:
              kirilov:
                train:
                   uri: train.lst
                   annotation: train.rttm
                   annotated: train.uem
    

    and put additional files near database.yml:

    kirilov
    ├── database.yml
    ├── kirilov.wav
    ├── train.lst
    ├── train.rttm
    └── train.uem
    

    train.lst: kirilov

    train.rttm: SPEAKER kirilov 1 0.0 3600.0 <NA> <NA> Kirilov <NA> <NA>

    train.uem: kirilov NA 0.0 3600.0

    I assume it will say trainer to use kirilov.wav file and take 3600 seconds of audio from it to use for training.

    Now I finetune the models, current folder is /content/fine/kirilov, so database.yml is taken from the current directory:

    !pyannote-audio sad train --pretrained=sad_dihard --subset=train --to=1 --parallel=4 "/content/fine/sad" IK.SpeakerDiarization.kirilov
    !pyannote-audio scd train --pretrained=scd_dihard --subset=train --to=1 --parallel=4 "/content/fine/scd" IK.SpeakerDiarization.kirilov
    !pyannote-audio emb train --pretrained=emb_voxceleb --subset=train --to=1 --parallel=4 "/content/fine/emb" IK.SpeakerDiarization.kirilov
    

    Output looks like:

    Using cache found in /root/.cache/torch/hub/pyannote_pyannote-audio_develop

    Etc.

    And try to run pipeline with new .pt's:

    import os
    import torch
    from pyannote.audio.pipeline import SpeakerDiarization
    pipeline = SpeakerDiarization(embedding = "/content/fine/emb/train/IK.SpeakerDiarization.kirilov.train/weights/0001.pt", 
                                  sad_scores = "/content/fine/sad/train/IK.SpeakerDiarization.kirilov.train/weights/0001.pt",
                                  scd_scores = "/content/fine/scd/train/IK.SpeakerDiarization.kirilov.train/weights/0001.pt",
                                  method= "affinity_propagation")
    
    #params from dia_dihard\train\X.SpeakerDiarization.DIHARD_Official.development\params.yml
    pipeline.load_params("/content/drive/My Drive/pyannote/params.yml")
    FILE = {'audio': "/content/groundtruth/new.wav"}
    diarization = pipeline(FILE)
    diarization
    

    The result is that for my new.wav the whole audio is recognized as speaker talking without pauses. So I assume that the models were broken. And it does not matter if I train for 1 epoch or for 100.

    In case I use:

    1. 0000.pt - I assume these are the original models
    pipeline = SpeakerDiarization(embedding = "/content/fine/emb/train/IK.SpeakerDiarization.kirilov.train/weights/0000.pt", 
                                  sad_scores = "/content/fine/sad/train/IK.SpeakerDiarization.kirilov.train/weights/0000.pt",
                                  scd_scores = "/content/fine/scd/train/IK.SpeakerDiarization.kirilov.train/weights/0000.pt",
                                  method= "affinity_propagation")
    

    or

    1. weights from original models
    pipeline = SpeakerDiarization(embedding = "/content/drive/My Drive/pyannote/emb_voxceleb/train/X.SpeakerDiarization.VoxCeleb.train/weights/0326.pt", 
                                 sad_scores = "/content/drive/My Drive/pyannote/sad_dihard/sad_dihard/train/X.SpeakerDiarization.DIHARD_Official.train/weights/0231.pt",
                                 scd_scores = "/content/drive/My Drive/pyannote/scd_dihard/train/X.SpeakerDiarization.DIHARD_Official.train/weights/0421.pt",
                                 method= "affinity_propagation")
    

    everything is ok and the result is similar to

    pipeline = torch.hub.load('pyannote/pyannote-audio', 'dia_dihard')
    FILE = {'audio': "/content/groundtruth/new.wav"}
    diarization = pipeline(FILE)
    diarization
    

    Could you please advise what could be wrong with my training\finetuning process?

    references #1, added disk store abstraction and used it in segmentati…

    …on and diarization

    When I run the segmentation or speaker diarization pipelines on very long audio files (>= 2 hours) the existing code is taking up too much RAM and my process is killed by the OOM killer.

    In this PR I introduce a DiskStore abstraction which I employed in many places in the segmentation and diarization pipelines to back some numpy arrays and/or Pytorch tensors with disk storage (using memory mapping).

    After the modifications, I am able to successfully run the pipeline on my long audio files (with significantly reduced memory consumption and minimal impact on the run time).

    Using Disk Store:

    from pyannote.audio.utils.diskstore import DiskStore
    
    dstore_path = "/home/prashanth/tmp/dstore"
    if not os.path.exists(dstore_path):
        os.makedirs(dstore_path)
    dstore = DiskStore(dstore_path)
    
    ...
    
    diarization = pipeline(audio, hook=hook, disk_store=dstore)
    dstore.cleanup() # deletes on disk files
    

    I noticed that loading the Audio input itself was a substantial cause of memory consumption so I wrote this piece of code to alleviate the memory load. It wasn't obvious where and how to integrate the functionality into pyannote so I am pasting the code below. In addition to conserving memory, it also decodes the input audio using multiple cores to speed up the operation for large files. Note that if the sample rate of the the input audio file is not 16Khz as expected by the pipelines, I use ffmpeg to convert first (in order to prevent the existing code from downsampling and creating an in-memory copy of the audio data)

    I am still working on figuring out a way to get past memory consumption issues with Agglomerative Clustering on a very large number of embeddings. If I am able to make progress there, I will issue a separate PR.

    Fixes for PytorchLightning >= 1.8

    Adjust to PytorchLightning API changes in version 1.8.0. I did some testing to make sure nothing broke, including model training/finetuning and loading from pretrained/HF-hub; however, my tests likely didn't cover everything.

    Will it work on real time streaming data ?

    I am currently running it on Apple M2 chip it is taking way much time comparing to Colab. Is there a way that pipeline could be modified to streaming data, and combined with some transcription service ?

    about pipeline when use gpu,and some questions?

    I really appreciate your help! Here are some of my questions: 1 When I use token, Is my data uploaded to the cloud server? The data is analyzed on the cloud server and sent back to me? 2 This is too slow, can I use a local GPU? How do you use it?
