一、什么是SYN6288模块
1、概述
SYN6288 中文语音合成芯片是北京宇音天下科技有限公司于2010 年初推出的一款性/价比更高，效果更自然的一款中高端语音合成芯片。SYN6288 通过异步串口（UART）通讯方式，接收待合成的文本数据，实现文本到语音（或TTS 语音）的转换。
宇音天下于2002 年最早研制出国内首款语音合成芯片 OSYNO6188。公司最新推出的 SYN6288 语音合成芯片，继承了 OSYNO6188 语音芯片的优秀特点：最小 SSOP28L 贴片封装、硬件接口简单、低功耗、音色清亮圆润、极高的性/价比；除此之外，SYN6288 在识别文本/数字/字符串更智能、更准确，语音合成自然度更好、可懂度更高。
2、芯片引脚图
二、使用方法
1、直接使用串口
硬件连接方式如下：
SYN6288引脚： RX --> PA2 TX --> PA3 VCC --> 5V GND --> GND 2、软件设置如下：
请注意：本次实验，我是用的是串口2，并且波特率选择为9600
3、实物连接图
2、关键函数
syn6288.c文件如下：
#include "syn6288.h" #include "usart.h" #include "string.h" //Music:选择背景音乐。0:无背景音乐，1~15：选择背景音乐 void SYN_FrameInfo(uint8_t Music, uint8_t *HZdata) { /****************需要发送的文本**********************************/ unsigned char Frame_Info[50]; unsigned char HZ_Length; unsigned char ecc = 0; //定义校验字节 unsigned int i = 0; HZ_Length = strlen((char*)HZdata); //需要发送文本的长度 /*****************帧固定配置信息**************************************/ Frame_Info[0] = 0xFD ; //构造帧头FD Frame_Info[1] = 0x00 ; //构造数据区长度的高字节 Frame_Info[2] = HZ_Length + 3; //构造数据区长度的低字节 Frame_Info[3] = 0x01 ; //构造命令字：合成播放命令 Frame_Info[4] = 0x01 | Music << 4 ; //构造命令参数：背景音乐设定 /*******************校验码计算***************************************/ for(i = 0; i < 5; i++) //依次发送构造好的5个帧头字节 { ecc = ecc ^ (Frame_Info[i]); //对发送的字节进行异或校验 } for(i = 0; i < HZ_Length; i++) //依次发送待合成的文本数据 { ecc = ecc ^ (HZdata[i]); //对发送的字节进行异或校验 } /*******************发送帧信息***************************************/ memcpy(&Frame_Info[5], HZdata, HZ_Length); Frame_Info[5 + HZ_Length] = ecc; HAL_UART_Transmit(&huart2,Frame_Info,5 + HZ_Length + 1,10000); } /*********************************************************** * 名 称： YS_SYN_Set(u8 *Info_data) * 功 能： 主函数 程序入口 * 入口参数： *Info_data:固定的配置信息变量 * 出口参数： * 说 明：本函数用于配置，停止合成、暂停合成等设置 ，默认波特率9600bps。 * 调用方法：通过调用已经定义的相关数组进行配置。 **********************************************************/ void YS_SYN_Set(uint8_t *Info_data) { uint8_t Com_Len; Com_Len = strlen((char*)Info_data); HAL_UART_Transmit(&huart2,Info_data,Com_Len,10000); } syn6288.h如下
#ifndef __SYN6288_H #define __SYN6288_H #include "stm32f1xx_hal.h" void SYN_FrameInfo(uint8_t Music, uint8_t *HZdata); void YS_SYN_Set(uint8_t *Info_data); #endif main.c如下：
请注意：在main.c中，有以下代码需要重点关注：
[vx]：前景文本播放音量，x音量值，取值：0~16（其中0为静音） [mx]：背景音乐音量，x为音量值，取值：0~16（其中0为静音） [tx]：词语语速，x为词语语速值，取值：0~5（5为最高语速） /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2024 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the * License.
