1.3 初始化

user_main.c中添加头文件包含

Code: Select all

#if defined(DEMO_IPC_VOICE_ENABLE) && (DEMO_IPC_VOICE_ENABLE == 1)
#include "tuya_ipc_voice_demo.h"
#endif

在tuya_ipc_sdk_mqtt_online_proc中添加自定义语音初始化

Code: Select all

#if defined(DEMO_IPC_VOICE_ENABLE) && (DEMO_IPC_VOICE_ENABLE == 1)
    TUYA_APP_Enable_Voice();
#endif

1.4 编译宏

在tuya_ipc_demo_default_cfg.h头文件中添加编译宏定义DEMO_IPC_VOICE_ENABLE

Code: Select all

#define DEMO_IPC_VOICE_ENABLE 1

2. 环境搭建

2.1 工具安装

为了能够在Ubuntu系统中演示自定义语音的播放功能，需要安装alsa-lib库，安装命令：

Code: Select all

sudo apt-get install libasound2-dev

2.2 创建音频缓存文件夹

为了能够缓存下载的音频文件，demo中将下载完的音频文件默认缓存在/tmp/voice文件夹下，用户需手动创建/tmp/voice文件夹。

用户如需更改缓存文件夹，可自行更改tuya_ipc_voice_demo.c中的VOICE_FILE_PATH宏定义。
