What is Automatic Speech Recognition Dataset?

An Automatic Speech Recognition (ASR) dataset is a collection of audio recordings and their corresponding transcriptions used to train and evaluate speech recognition systems. These datasets are crucial for developing and refining ASR models, as they provide the raw material needed for machine learning algorithms to learn how to accurately convert spoken language into text.

ASR datasets are used in several stages of ASR development:


The dataset is used to teach the ASR model how to recognize and transcribe speech by adjusting its parameters to minimize the error between predicted and actual transcriptions.


A subset of the dataset is used to fine-tune the model and prevent overfitting by providing feedback on its performance during training.


Another subset, not used during training, is employed to evaluate the final performance and accuracy of the ASR system.

Popular ASR datasets include LibriSpeech, Common Voice, and TED-LIUM, each offering a diverse range of audio samples and transcriptions to facilitate the development of robust and versatile speech recognition systems.
