How to Use Whisper Large v2 PL for Automatic Speech Recognition

Dec 23, 2022 | Educational

If you’re venturing into the world of Automatic Speech Recognition (ASR) and want to leverage the power of Whisper Large v2 PL, you’ve come to the right place. In this guide, we will unravel the model’s functionalities, training methods, and metrics it operates upon. Let’s get started!

Understanding Automatic Speech Recognition and Whisper Large v2 PL

When we talk about Automatic Speech Recognition (ASR), envision a translator that transforms spoken language into written text. Imagine having a vast library of spoken words, and your model is the diligent librarian who accurately notes everything down, making it easily accessible. Whisper Large v2 PL is that diligent librarian. It’s a fine-tuned model developed by OpenAI, specifically optimized for the Polish language using the Common Voice 11.0 dataset.

Key Results from the Evaluation Set

The Whisper Large v2 PL has achieved impressive metrics that reflect its efficiency in transcription:

  • Loss: 0.4222
  • Word Error Rate (WER): 6.9125

Training and Evaluation Data

This model is trained on various datasets and engineered to handle specific Polish language tasks, providing high accuracy in transcription tasks.

Training Procedure and Hyperparameters

When it comes to training the model, various hyperparameters play pivotal roles, similar to the ingredients in a recipe. Each contributes uniquely to the end result of your dish (or in this case, the trained model).


learning_rate: 1e-05
train_batch_size: 8
eval_batch_size: 4
seed: 42
gradient_accumulation_steps: 8
total_train_batch_size: 64
optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: linear
lr_scheduler_warmup_steps: 500
training_steps: 5000
mixed_precision_training: Native AMP

This array of hyperparameters controls everything from the learning rate to the batch size, which ultimately shapes the behavior and performance of the Whisper Large v2 PL model.

How to Implement the Model

To see Whisper Large v2 PL in action, you’ll typically follow these steps:

  1. Load the model and necessary libraries.
  2. Prepare your audio data.
  3. Run the audio through the model and compute the transcriptions.

Troubleshooting Common Issues

While using the Whisper model, you may encounter some bumps along the road. Here are some troubleshooting tips:

  • Issue: Model fails to load properly.
    Solution: Ensure that the necessary libraries like Transformers and PyTorch are correctly installed and compatible with the model.
  • Issue: Inaccurate transcriptions.
    Solution: Check the quality of your audio data, as noisy recordings can severely hinder performance.
  • Issue: High latency in processing audio.
    Solution: Consider adjusting the batch size or utilizing a more powerful hardware configuration.
