Model overview

The embedding model from pyannote is a speaker embedding model that uses the canonical x-vector TDNN-based architecture, but with filter banks replaced by trainable SincNet features. This model reaches 2.8% equal error rate (EER) on the VoxCeleb 1 test set without any additional processing like voice activity detection (VAD) or probabilistic linear discriminant analysis (PLDA). Compared to similar models like the segmentation and speaker-diarization models from pyannote, the embedding model focuses specifically on extracting speaker embeddings from audio.

Model inputs and outputs

The embedding model takes in an audio file and outputs a numpy array representing the speaker embedding for the entire file. This embedding can then be used for tasks like speaker verification, where you can compare the embeddings of two speakers to determine how similar they are.

Inputs

  • Audio file: The model accepts a single audio file as input, which can be in any format supported by the underlying audio library.

Outputs

  • Speaker embedding: The model outputs a numpy array of shape (1, D), where D is the dimensionality of the speaker embedding. This embedding represents the speaker characteristics extracted from the entire input audio file.

Capabilities

The embedding model is capable of extracting robust speaker embeddings from audio data, which can be useful for a variety of applications like speaker verification, diarization, and identification. By using trainable SincNet features, the model is able to achieve strong performance on speaker verification tasks without the need for additional processing steps.

What can I use it for?

The embedding model can be used in a variety of applications that require speaker-level information, such as:

  • Speaker verification: The model can be used to generate speaker embeddings that can be compared to determine if two audio samples are from the same speaker. This is useful for applications like access control or fraud detection.
  • Speaker diarization: The model's embeddings can be used as input to a speaker diarization system to identify and segment different speakers within a longer audio recording.
  • Speaker identification: The model's embeddings can be used to identify specific speakers within a dataset, which can be useful for applications like transcription or meeting analysis.

Things to try

One interesting thing to try with the embedding model is to use it in combination with other audio processing techniques, such as voice activity detection (VAD) or probabilistic linear discriminant analysis (PLDA). By combining the model's speaker embeddings with these additional processing steps, you may be able to achieve even better performance on speaker verification and diarization tasks.

Another interesting experiment would be to fine-tune the model on a specific dataset or domain of interest, which could potentially improve its performance on certain types of audio data. The maintainer's profile mentions that they offer consulting services to help users make the most of their open-source models, which could be a valuable resource for those looking to customize or optimize the embedding model for their specific needs.

The speaker-diarization-3.1 model is a pipeline developed by the pyannote team that performs speaker diarization on audio data. It is an updated version of the speaker-diarization-3.0 model, removing the problematic use of onnxruntime and running the speaker segmentation and embedding entirely in PyTorch. This should ease deployment and potentially speed up inference. The model takes in mono audio sampled at 16kHz and outputs speaker diarization as an Annotation instance. It can handle stereo or multi-channel audio by automatically downmixing to mono, and it can resample audio files to 16kHz upon loading. Compared to the previous speaker-diarization-3.0 model, this updated version should provide a smoother and more efficient experience for users integrating the model into their applications. Model inputs and outputs Inputs Mono audio sampled at 16kHz**: The pipeline accepts a single-channel audio file sampled at 16kHz. It can automatically handle stereo or multi-channel audio by downmixing to mono. Outputs Speaker diarization**: The pipeline outputs a pyannote.core.Annotation instance containing the speaker diarization for the input audio. Capabilities The speaker-diarization-3.1 model is capable of accurately segmenting and labeling different speakers within an audio recording. It can handle challenging scenarios like overlapping speech and varying numbers of speakers. The model has been benchmarked on a wide range of datasets, including AISHELL-4, AliMeeting, AMI, AVA-AVD, DIHARD 3, MSDWild, REPERE, and VoxConverse, demonstrating robust performance across diverse audio scenarios. What can I use it for? The speaker-diarization-3.1 model can be valuable for a variety of audio-based applications that require identifying and separating different speakers. Some potential use cases include: Meeting transcription and analysis**: Automatically segmenting and labeling speakers in audio recordings of meetings, conferences, or interviews to facilitate post-processing and analysis. Audio forensics and investigation**: Separating and identifying speakers in audio evidence to aid in investigations and legal proceedings. Podcast and audio content production**: Streamlining the editing and post-production process for podcasts, audio books, and other multimedia content by automating speaker segmentation. Conversational AI and voice assistants**: Improving the ability of voice-based systems to track and respond to multiple speakers in real-time conversations. Things to try One interesting aspect of the speaker-diarization-3.1 model is its ability to control the number of speakers expected in the audio. By using the num_speakers, min_speakers, and max_speakers options, you can fine-tune the model's behavior to better suit your specific use case. For example, if you know the audio you're processing will have a fixed number of speakers, you can set num_speakers to that value to potentially improve the model's accuracy. Additionally, the model provides hooks for monitoring the progress of the pipeline, which can be useful for long-running or batch processing tasks. By using the ProgressHook, you can gain visibility into the model's performance and troubleshoot any issues that may arise.
