gTTS, which stands for Google Text-to-Speech, is a Python library and command-line interface tool that allows users to interact with the text-to-speech API provided by Google Translate. This tool enables users to write spoken audio data in mp3 format to various outputs, such as a file, a bytestring for additional audio processing, or even directly to stdout. Additionally, it offers the option to pre-generate URLs for Google Translate TTS requests, which can be utilized by other external applications. The library features a customizable tokenizer specifically designed for speech, allowing for arbitrary lengths of text to be processed while maintaining correct intonation, handling of abbreviations, decimal numbers, and more. Furthermore, it includes customizable text preprocessing capabilities that can address pronunciation issues, enhancing the overall quality of the speech output. With these diverse functionalities, gTTS serves as a versatile tool for generating high-quality spoken audio from text.
