HOW GTS.AI can be right Audio Dataset

The text dataset may require cleaning and preprocessing steps to remove noise, correct errors, standardize formats, and handle any specific challenges in the data. This process may involve techniques like removing HTML tags, removing punctuation, converting text to lowercase, and tokenizing the text into individual words or subwords. This dataset contains text samples that were not seen during training and is used to assess the model's ability to generalize to new data. Metrics such as accuracy, precision, recall, or F1 score may be used to evaluate the model's performance.
