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.
