Frequently Asked Questions
Q1: How to send text to XFS5152CE for voice playback?
A1: MCU packages text into standard data frame, transmits via UART/SPI/I2C. The chip auto decodes text and outputs voice.
Q2: Can the chip read dates, time and currency correctly?
A2: Yes. Built-in intelligent algorithm identifies numbers, dates, currency and percentages with natural reading logic.
Q3: Do I need external power amplifier for speakers?
A3: It supports direct drive for buzzers. For loud industrial speakers, match analog output with amplifier chip like LM386.
Q4: What text encoding formats does the chip support?
A4: GB2312, GBK, BIG5 and Unicode Little-Endian, configurable in initialization command.
Q5: Does offline voice recognition rely on cloud network?
A5: No cloud required. Built-in offline engine supports up to 30 customizable voice commands.
Q6: What supply voltage range is applicable for XFS5152CE?
A6: Wide 3.3V~5V working voltage, compatible with most mainstream embedded mainboards.
Q7: Can I adjust playback speed and tone of synthesized voice?
