Text-to-speech (TTS) engines are widely used in assistive technology, communication systems, and automation in various industries. They’re essential for individuals with visual impairments or reading disabilities, enabling them to access written content audibly.<\/p>\n

TTS also assists students with dyslexia, language learners, and individuals with learning difficulties. Virtual assistants like Siri, Alexa, and Google Assistant also use it to respond to user requests, while GPS<\/a> devices and apps<\/a> provide spoken navigation. Additionally, TTS is used in audiobooks, podcasts, and video games for voiceovers and narration.<\/p>\n

In this project, we’ll build a TTS engine using an ESP32<\/a>. The system will read a number the user enters on a webpage hosted by the ESP32. The ESP32 will then read the number aloud through a connected speaker.<\/p>\n
