# 三哥AI大模型对话工程开源
基本例程采用esp-adf里面的pipeline_baidu_speech_mp3例程，在这个例程基础上修改加入百度语音转文字，minimax大模型对话，百度文字转语音程序。

程序参考了力创实战派esp32c3的程序。采用建民大佬的硬件板卡，兼容乐鑫官网esp32_s3_korvo2_v3板卡，略微有改动。在此一并感谢大力支持！
显示部分在esp-adf\examples\display\music_player例程基础上修改加入的ai-toys工程里面，加入调通LVGL屏幕显示，调通了GT911触摸程序。
目前仍旧有bug，还有一些功能，比如语音唤醒屏幕显示等，三哥会持续修改更新。
有啥技术问题可以联系三哥微信：robot3g，三哥拉你进开发者联盟vx，或Q群：174742054（开发者联盟），进群讨论。

## 简介

使用 ADF 进行VTT（voice to text），之后text发到minimax进行ai大模型交互，返回的txt由百度在线语音合成 (text-to-speech, TTS) 服务生成的音频通过i2s送到音频codec进行播放。本示例默认是中文文本，但也支持其他一些语言，更多的技术细节可以参考 [百度语音合成文档](http://ai.baidu.com/tech/speech/tts) 页面。

获取百度在线语音转文字和语音合成 MP3 音频管道如下：

```
[codec_chip]---> [i2s_reader] ---> [http_stream_writer] ---> [baidu_vtt_server]

[baidu_tts_server] ---> http_stream ---> mp3_decoder ---> i2s_stream ---> [codec_chip]
```

## 环境搭建
环境搭建请参考三哥的CSDN笔记：36集【新手必看】vscode搭建ESP32开发环境终极篇
https://blog.csdn.net/phlr5/article/details/141598455
B站配套视频：
https://www.bilibili.com/video/BV1NksAeuEAb
配套视频也可以在抖音、B站、小红书、微信短视频、快手，搜索柔贝特三哥，观看同名短视频就好。
【软硬件代码下载】
https://gitee.com/robot3g/ai_toys_publish
硬件主板：ai_toys_publish\hardware\01-RTC_LCD_V3.0.eprj 
硬件屏幕板：ai_toys_publish\hardware\01-RTC_LEB18P_V2.0.eprj 
有需要硬件板卡的，三哥后面整理好后会在淘宝、B站工坊和抖店上架。

### 硬件要求
硬件兼容ESP32_S3_KORVO2_V3_BOARD，其他板卡请参考 `$ADF_PATH/examples/README_CN.md` 文档中[例程与乐鑫音频开发板的兼容性表格](../../README_CN.md#例程与乐鑫音频开发板的兼容性)中有标注，表格中标有绿色复选框的开发板均可运行本例程。请记住，如下面的 [配置](#配置) 一节所述，可以在 `menuconfig` 中选择开发板。

## 编译和下载

### IDF 默认分支IDF release/v5.2.2

### 配置
本工程默认配置大家可以看代码里面的sdkconfig.defaults和sdkconfig.defaults.esp32s3文件。

本例程默认选择的开发板是 `CONFIG_AUDIO_BOARD_CUSTOM`，如果需要在其他的开发板上运行此例程，则需要在 menuconfig 中选择开发板的配置，例如选择 `ESP32-Lyrat-Mini V1.1`。

```
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
```

本例需要连接 Wi-Fi 网络，通过运行 `menuconfig` 来配置 Wi-Fi 信息。

```
 menuconfig > Example Configuration > `WiFi SSID` and `WiFi Password` and 'Baidu speech access key ID' and "Baidu speech access secret"
 
```

要在百度在线语音合成页面申请语音合成应用，并把申请到的 `API Key` 和 `Secret Key` 分别填入 `menuconfig` 的配置中，用来和百度 TTS 服务器鉴权。
在minimax里面申请id和key。
具体可以参考三哥的CSDN笔记《21-22集 ESP32-IDF开发教程编译运行机器人对话工程-《MCU嵌入式AI开发笔记》》
https://editor.csdn.net/md/?articleId=140510897
和22集 如何minimax密钥和groupid-《MCU嵌入式AI开发笔记》
https://editor.csdn.net/md/?articleId=140598712
和相同集数的视频介绍。

在minimax_chat.c中修改groupid
62行修改：.url = "https://api.minimax.chat/v1/text/chatcompletion_pro?GroupId=xxx",  // 这里xxx替换成自己的GroupId
在ai_toys.c中第85行修改：
// 把下面的双引号里面的替换成自己的token_key
const char * minimax_key = "Bearer eyJhbGciOiJSxxx";

### 编译和下载

## 如何使用例程

### 功能和用法

- 例程开始运行后，按照配置首先尝试连接 Wi-Fi 网络，之后就可以按键聊天了。
