The Role of Datasets in Text-to-Speech Technology

Text-to-speech (TTS) or speech synthesis technology has made remarkable strides in recent years, revolutionizing the way humans interact with computers and digital devices. This cutting-edge technology converts written text into natural-sounding speech, enabling applications like voice assistants, audiobooks, and accessibility tools. The development of high-quality TTS systems heavily relies on the availability and quality of datasets used for training the models.

Creating a high-quality TTS dataset is a meticulous process that involves multiple stages. Firstly, large amounts of speech data are collected from various sources, including public domain recordings, audiobooks, and crowd-sourced contributions. This diverse dataset captures the richness of linguistic variations and accents, ensuring that the synthesized speech is inclusive and caters to a wide range of users.

Once the raw speech data is collected, it undergoes a rigorous cleaning process to remove any background noise or disturbances. The data is then meticulously annotated, aligning the corresponding text with the speech segments. These annotations are essential for training the TTS models as they provide the necessary information for the system to learn the relationship between text and speech.

In the globalized world we live in, multilingual capabilities are a fundamental requirement for TTS systems. Multilingual datasets are invaluable for training models to accurately synthesize speech in multiple languages. These datasets introduce the TTS model to the phonetic and linguistic peculiarities of various languages, enhancing its adaptability and usability.
