# Xiaozhi ESP-32 Back-end Service (xiaozhi-esp32-server)
|
||
|
||
（[中文](README.md) | English）
|
||
|
||
This project provides backend services for the open-source smart hardware
|
||
project [xiaozhi-esp32](https://github.com/78/xiaozhi-esp32)。Implemented in Python following
|
||
the[Xiaozhi Communication Protocol](https://ccnphfhqs21z.feishu.cn/wiki/M0XiwldO9iJwHikpXD5cEx71nKh)。
|
||
|
||
## Target Audience
|
||
|
||
This project requires compatible esp32 hardware devices. If you have purchased esp32 hardware, successfully connected to
|
||
Xiage's deployed backend, and wish to independently set up the `xiaozhi-esp32` backend service, this project is for
|
||
you.

# Deployment
|
||
|
||
This project supports rapid deployment of docker and local source code operation. If you want to have a quick
|
||
experience, it is recommended to use docker to deploy. If you want to have an in-depth understanding of this project, it
|
||
is recommended to run the local source code.
|
||
|
||
## Method 1: Quick deployment of docker
|
||
|
||
The docker image has supported the CPU of x86 architecture and arm64 architecture, and supports running on Chinese
|
||
operating systems.
|
||
|
||
1. Install docker
|
||
|
||
If your computer has not installed docker, you can follow the tutorial here to install
|
||
it:[Install docker](https://www.runoob.com/docker/ubuntu-docker-install.html)
|
||
|
||
2. Create a directory
|
||
|
||
After installation, you need to find a directory for the configuration file for this project. Let's call it the
|
||
`project directory` for the time being. This directory is preferably a newly created empty directory.
|
||
|
||
3. Download the configuration file
|
||
|
||
Open with a browser[This link](https://github.com/xinnan-tech/xiaozhi-esp32-server/blob/main/config.yaml)。
|
||
|
||
On the right side of the page, find the button named `RAW`, next to the `RAW` button, find the download icon, click the
|
||
Download button, and download the `config.yaml` file. Download the file to your `project directory`.
|
||
|
||
4. Configure Project
|
||
|
||
Modify the `config.yaml` file to configure the various parameters required for this project. The default LLM uses
|
||
`ChatGLMLLM`, you need to configure the key to start.
|
||
The default TTS uses `EdgeTTS`. This does not require configuration. If you need to replace it with`Doubao TTS`, you
|
||
need to
|
||
configure the key.
|
||
|
||
Configuration description: This is the default component of each function, such as LLM default to use the `ChatGLMLLM`
|
||
model. If you need to switch the model, it is the corresponding name.
|
||
|
||
The default configuration of this project is only the lowest operating cost configuration（`glm-4-flash`and`EdgeTTS`are
|
||
free），If you need to be better and faster, you need to combine the use of the deployment environment to switch the use
|
||
of each component。
|
||
|
||
```
|
||
selected_module:
|
||
ASR: FunASR
|
||
VAD: SileroVAD
|
||
LLM: ChatGLMLLM
|
||
TTS: EdgeTTS
|
||
```
|
||
|
||
For example, modify the components used by `llm`, depending on which` llm` supports this project, as follows, it
|
||
supports `Deepseekllm` and` Chatglmllm`. You are modified to the corresponding LLM in `selectd_module`
|
||
|
||
```
|
||
LLM:
|
||
AliLLM:
|
||
...
|
||
DeepSeekLLM:
|
||
...
|
||
ChatGLMLLM:
|
||
...
|
||
DifyLLM:
|
||
...
|
||
```
|
||
|
||
Some services, for example, if you use the TTS` of the `dify` and` bean bags, you need a key, remember to add the
|
||
configuration file!
|
||
|
||
5. Execute the docker command
|
||
|
||
Open the command line tool, `cd` enter your `project directory`, and execute the following command
|
||
|
||
```
|
||
#If you are Linux, execute
|
||
ls
|
||
#If you are Windows, execute
|
||
dir
|
||
```
|
||
|
||
If you can see the `config.yaml` file, you have indeed entered the `project directory`, and then execute the following
|
||
command:
|
||
|
||
```
|
||
docker run -d --name xiaozhi-esp32-server --restart always --security-opt seccomp:unconfined -p 8000:8000 -v $(pwd)/config.yaml:/opt/xiaozhi-es32-server/config.yaml ccr.ccs.tencentyun.com/xinnan/xiaozhi-esp32-server:latest
|
||
```
|
||
|
||
If executed for the first time, it may take several minutes, and you have to be patient to wait for it to complete the
|
||
pull. After normal pulling is completed, you can execute the following command on the command line to see if the service
|
||
is started successfully.
|
||
|
||
```
|
||
docker ps
|
||
```
|
||
|
||
If you can see `xiaozhi-server`, it means that the service starts successfully. Then you can further execute the
|
||
following command to view the service log
|
||
|
||
```
|
||
docker logs -f xiaozhi-esp32-server
|
||
```
|
||
|
||
If you can see, similar to the following logs, it is a sign that the service of this project is successfully launched.
|
||
|
||
```
|
||
2025-xx-xx xx:51:59,492 - core.server - INFO - Server is running at ws://xx.xx.xx.xxx:8000
|
||
2025-xx-xx xx:51:59,516 - websockets.server - INFO - server listening on 0.0.0.0:8000
|
||
```
|
||
|
||
Next, you can start `compiling esp32 firmware`. Please go down and turn to the relevant chapter on
|
||
`compiling esp32 firmware`. So since you are deploying with docker, you have to check the IP of your native computer by
|
||
yourself.
|
||
Normally, assuming your ip is `192.168.1.25`, then your interface address is: `ws://192.168.1.25:8000`. This information
|
||
is very useful, and it is required to `compile esp32 firmware` later.
|
||
|
||
## Method 2 : Local Source Code Deployment
|
||
|
||
### 1.Install Prerequisites
|
||
|
||
This project uses 'conda' to manage dependencies, and after installation, start executing the following commands:
|
||
|
||
```
|
||
conda remove -n xiaozhi-esp32-server --all -y
|
||
conda create -n xiaozhi-esp32-server python=3.10 -y
|
||
conda activate xiaozhi-esp32-server
|
||
```
|
||
|
||
After executing the above command, if your computer is Windows or Mac, execute the following statement:
|
||
|
||
```
|
||
conda activate xiaozhi-esp32-server
|
||
conda install conda-forge::libopus
|
||
conda install conda-forge::ffmpeg
|
||
```
|
||
|
||
If your computer is ubuntu, execute the following statement:
|
||
|
||
```
|
||
apt-get install libopus0 ffmpeg
|
||
```
|
||
|
||
### 2.Install Dependencies
|
||
|
||
```
|
||
# Clone the project
|
||
cd xiaozhi-esp32-server
|
||
conda activate xiaozhi-esp32-server
|
||
pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/
|
||
pip install -r requirements.txt
|
||
```
|
||
|
||
### 3.Download ASR Model
|
||
|
||
Download [SenseVoiceSmall](https://modelscope.cn/models/iic/SenseVoiceSmall/resolve/master/model.pt) to
|
||
`model/SenseVoiceSmall`.
|
||
|
||
By default, the `SenseVoiceSmall` model is used to convert voice to text. Because the model is large, it needs to be
|
||
downloaded independently. After downloading, place the `model.pt` file in the `model/SenseVoiceSmall` directory. Choose
|
||
any of the following two download routes.
|
||
|
||
- Line 1: Download Ali Magic
|
||
Tower[SenseVoiceSmall](https://modelscope.cn/models/iic/SenseVoiceSmall/resolve/master/model.pt)
|
||
- Line 2: Baidu Netdisk download[SenseVoiceSmall](https://pan.baidu.com/share/init?surl=QlgM58FHhYv1tFnUT_A8Sg&pwd=qvna)
|
||

|
||
|
||
### 4.Configure Project
|
||
|
||
Modify the `config.yaml` file to configure the various parameters required for this project. The default LLM uses
|
||
`ChatGLMLLM`, you need to configure the key to start.
|
||
The default TTS uses `EdgeTTS`. This does not require configuration. If you need to replace it with`Doubao TTS`, you
|
||
need to
|
||
configure the key.
|
||
|
||
Configuration description: This is the default component of each function, such as LLM default to use the `ChatGLMLLM`
|
||
model. If you need to switch the model, it is the corresponding name.
|
||
|
||
The default configuration of this project is only the lowest operating cost configuration（`glm-4-flash`and`EdgeTTS`are
|
||
free），If you need to be better and faster, you need to combine the use of the deployment environment to switch the use
|
||
of each component。
|
||
|
||
```
|
||
selected_module:
|
||
ASR: FunASR
|
||
VAD: SileroVAD
|
||
LLM: ChatGLMLLM
|
||
TTS: EdgeTTS
|
||
```
|
||
|
||
For example, modify the components used by `llm`, depending on which` llm` supports this project, as follows, it
|
||
supports `Deepseekllm` and` Chatglmllm`. You are modified to the corresponding LLM in `selectd_module`
|
||
|
||
```
|
||
LLM:
|
||
DeepSeekLLM:
|
||
...
|
||
ChatGLMLLM:
|
||
...
|
||
DifyLLM:
|
||
...
|
||
```
|
||
|
||
Some services, for example, if you use the TTS` of the `dify` and` bean bags, you need a key, remember to add the
|
||
configuration file!
|
||
|
||
### 5.Run the Project
|
||
|
||
Run the Project
|
||
|
||
```
|
||
# Make sure to execute in the root directory of this project
|
||
conda activate xiaozhi-esp32-server
|
||
python app.py
|
||
```
|
||
|
||
You'll see the WebSocket endpoint in logs:
|
||
|
||
```
|
||
2025-xx-xx xx:51:59,492 - core.server - INFO - Server is running at ws://192.168.1.25:8000
|
||
2025-xx-xx xx:51:59,516 - websockets.server - INFO - server listening on 0.0.0.0:8000
|
||
```
|
||
|
||
Among them, the `ws://192.168.1.25:8000` is the interface address provided by this project. Of course, your own machine
|
||
is different from mine. Remember to find your own address.
|
||
|
||
# Compile ESP32 Firmware
|
||
|
||
1. Download `xiaozhi-esp32` project, configure the project environment according to this
|
||
tutorial [" Windows builds ESP IDF 5.3.2 Development Environment and Compiles Xiaozhi "](https://icnynnzcwou8.feishu.cn/wiki/JEYDwTTALi5s2zkGlFGcDiRknXf)
|
||
Cure
|
||
|
||
2. Open the `xiaozhi-esp32/main/kconfig.projbuild` file, find the content of the` websocket_url` `default`, change the
|
||
` wss: // api.tenclass.net` to your own address, such as
|
||
|
||
Before modification:
|
||
|
||
```
|
||
config WEBSOCKET_URL
|
||
depends on CONNECTION_TYPE_WEBSOCKET
|
||
string "Websocket URL"
|
||
default "wss://api.tenclass.net/xiaozhi/v1/"
|
||
help
|
||
Communication with the server through websocket after wake up.
|
||
```
|
||
|
||
After modification (example):
|
||
|
||
```
|
||
config WEBSOCKET_URL
|
||
depends on CONNECTION_TYPE_WEBSOCKET
|
||
string "Websocket URL"
|
||
default "ws://192.168.1.25:8000/xiaozhi/v1/"
|
||
help
|
||
Communication with the server through websocket after wake up.
|
||
```
|
||
|
||
3. Configure build settings:
|
||
|
||
```
|
||
# The terminal command line enters the root directory of xiaozhi-esp32
|
||
cd xiaozhi-esp32
|
||
# For example, the board I use is ESP32S3, so the compile target is ESP32S3. If your board is other models, please replace it with the corresponding model
|
||
idf.py set-target esp32s3
|
||
# Enter the menu configuration
|
||
idf.py menuconfig
|
||
```
|
||
|
||
|
||
|
||
After entering the menu configuration, then enter `xiaozhi assistant`, set the` connection_type` to `websocket`
|
||
Go back to the main menu, then enter `xiaozhi assistant`, set the `BOARD_TYPE` of your board
|
||
Save exit and return to the terminal command line.
|
||
|
||
|
||
|
||
4. Build and package:
|
||
|
||
```
|
||
idf.py build
|
||
cd scripts
|
||
python release.py
|
||
```
|
||
|
||
After the compilation is successful, the firmware file `merged-binary.bin` is generated in the` build` directory in the
|
||
project root directory.
|
||
This `merged-binary.bin` is the firmware file that will be recorded on the hardware.
|
||
|
||
6. Flash
|
||
Connect the ESP32 device to the computer, use the Chrome browser, and open the following URL
|
||
|
||
```
|
||
https://espressif.github.io/esp-launchpad/
|
||
```
|
||
|
||
Open this
|
||
tutorial, [Flash Tools/Web -side Burning Folding Step (No IDF Development Environment)](https://ccnphfhqs21z.feishu.cn/wiki/Zpz4wXBtdimBrLk25WdcXzxcnNS).
|
||
Turn to: `Method 2: ESP-LAUNCHPAD browser web-end burning`, start from
|
||
`3. Burning firmware/download to the development board`, follow the tutorial operation.

# FAQ
|
||
|
||
## 1、TTS often fails, often overtime
|
||
|
||
Suggestion: If the `Edgetts` is slow or often fails, you can replace it with a bean bag TTS` with a volcanic engine. If
|
||
both are slow, the network environment may need to be optimized.
|
||
|
||
## 2、Big model reply is a bit slow
|
||
|
||
Suggestions: Both big models and TTS are dependent interfaces. If the network environment is not good, you can consider
|
||
changing the local model. Or try to switch different interface models.
|
||
|
||
## 3、Why is my ChatGLMLLM replying to a bit? Obviously it is Xiaozhi, but treats me as Xiaozhi.
|
||
|
||
Suggestion: You can modify the prompts in the configuration file first. You can also replace the free `GLM-4-FLASH` to
|
||
the model of other toll versions of `ChatGlm`.
|
||
|
||
## 4、I want to control the operation of electric lights, air conditioners, remote switching and other operations through Xiaozhi.
|
||
|
||
Suggestion: In the configuration file, set the `LLM` to`DifyLLM`, and then arrange the smart application by the
|
||
`Dify`.
|
||
|
||
## 5、I said very slowly, I paused, Xiaozhi always grabbed me, what to do.
|
||
|
||
Suggestion: In the configuration file, find this section, change the `min_silence_duration_ms` value, such as change to
|
||
` 1000`.
|
||
|
||
```
|
||
VAD:
|
||
SileroVAD:
|
||
threshold: 0.5
|
||
model_dir: models/snakers4_silero-vad
|
||
min_silence_duration_ms: 700 # 如果说话停顿比较长，可以把这个值设置大一些
|
||
```
