{"title":"Text-to-Speech Shield for Arduino","handle":"text-to-speech-shield-for-arduino","url":"/products/text-to-speech-shield-for-arduino","description":"Give your Arduino project a voice with this text-to-speech shield. Built around the IFLYTEK XFS5051CE speech synthesis chip, it converts text strings into spoken audio in English and Chinese, with support for both male and female voices and 11 adjustable speaking speeds.\n\nThe shield stacks directly onto standard Arduino boards and communicates over UART, I²C, or SPI. It includes a Run/Prog switch and a busy LED indicator. Just connect a speaker and start sending text — the shield handles all the synthesis work.\n\nKey Features\n\n\nXFS5051CE Speech Synthesis Chip – High-quality text-to-speech engine\n\nEnglish & Chinese Support – Including Cantonese dialect and mixed speech\n\nMale & Female Voices – Selectable voice output\n\n11 Speed Levels – Adjustable speaking rate\n\nThree Interfaces – UART, I²C, and SPI\n\nConfigurable Baud Rates – 4800, 9600, 57600, 115200\n\nRun/Prog Switch – Easy mode selection\n\nBusy LED Indicator – Shows when speech is being synthesised\n\n\nSpecifications\n\n\nChip: IFLYTEK XFS5051CE\n\nVoltage: 5 V\n\nInterfaces: UART, I²C, SPI\n\nBaud Rates: 4800 / 9600 / 57600 / 115200\n\nDimensions: 56 × 53 mm\n\nWeight: 26 g\n\n\n\nNote: Speaker is not included.
