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:
c
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:
c
#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
c
#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)
