Introduction

XFS5152CE is a highly integrated speech synthesis chip that supports Chinese and English text-to-speech synthesis. It also integrates voice encoding and decoding functions, enabling users to perform recording and playback. Additionally, it innovatively integrates a lightweight speech recognition function, supporting recognition of 30 command words with customization capability.

The chip supports synthesis of arbitrary Chinese and English text, including mixed Chinese-English reading. It is compatible with four encoding formats: GB2312, GBK, BIG5, and UNICODE. Each synthesis task supports up to 4K bytes of text input.

The chip performs text analysis and correctly identifies and processes common formats such as numbers, phone numbers, times, dates, and units of measurement based on built-in text matching rules. It can also determine the correct pronunciation of polyphones based on context, and supports mixed Chinese-English reading for bilingual text.

The chip supports voice codec functionality, allowing users to perform recording and playback directly. Internally integrated voice encoding and decoding units enable audio encoding and decoding for recording and playback. The codec features high compression ratio, low distortion, and low latency, supporting multiple codec bit rates. These characteristics make it well-suited for digital voice communication, voice storage, and other applications requiring digital voice processing.

The chip supports speech recognition of up to 30 command words. By default, it is pre-configured with 30 commonly used command words for automotive, alerting, and similar industries. Customers requiring different command words may request customization.

The chip integrates 80 built-in common alert tones, suitable for various applications including information prompts, ringtones, and alarms.

Three communication interfaces are supported: UART, I2C, and SPI. The UART interface supports four selectable baud rates: 4800 bps, 9600 bps, 57600 bps, and 115200 bps, configurable via hardware settings.

Multiple control commands are supported, including text synthesis, stop synthesis, pause synthesis, resume synthesis, status query, enter power-saving mode, and wake-up. The controller can operate the chip by sending control commands through the communication interface. The command set is straightforward and easy to use — for example, a unified "synthesis command" interface can trigger both alert tones and Chinese text playback, and synthesis parameters can be configured via tagged text.

Multiple methods are available for querying the chip's operating status, including: reading the status pin level, receiving automatically returned status bytes from the chip, and sending query commands to retrieve status feedback data.
