1. Configuration of language model

1. Open the official website of Chipintelli: https://platform.chipintelli.com/web#action=235&menu_id=198Chipintelli

2. Click on the speech model and click Create

First download the acoustic model and command word list

3. Click to play the announcement in the same way.

Download announcement word template

4. Open the broadcast word list and command word list table files

Fill in the command words and announcement words according to your needs

5. Download CI1122SDk

6. Upload the edited command word file

Generate language model

7. Download the announcement model

Same as 6, you can choose the tone yourself

Click save to download

This is the zip file downloaded in steps 6 and 7

8.Configure location

Open the CI112X_SDK_V1.2.9sampleinternalsample_1122firmware path under the SDK file

Prepare the downloaded files

Delete the asr files in the sdk file

Put the files from these two into the asr file

As shown in the picture

Delete files in dnn file

Copy the downloaded acoustic model and put it into it

Place the file in the picture into the user_filecmd_info file in the SDK directory

In addition, we also need to modify this Excel file

open a file

The announcement sound ID must correspond to the announcement word. If not used, other values ​​can be set.

Then select all the WAV files in the above picture and copy them to the SDK path voice[0]voice_zhinengguanjia_chn

Then run the cmd_info batch command

Click to merge partition bin files

Enter 1

End the first big step

2. We need to download a corresponding compiler to compile our SDK

Link: https://pan.baidu.com/s/1E9qOtgGWVxJfn33SlF05RA 
Extraction code: 2iy2

I installed the Chinese language package

deal_asr_msg_by_cmd_id is the function we want to debug

//**********************//

A problem I had before was the problem prompt of importing the project.

Some projects cannot be imported because they already exist in the workspace

Revise

The name defined in the .project file: <name>Project name</name> tag content is the same as the project to be imported.

Output instructions through the serial port

Note that the case selection corresponds to the command word id:

Click compile

After success, there will be a user.bin

Let’s merge the partitions again

Then click Package Upgrade

Then click Upgrade Firmware

Use a jumper cap to short the upgrade interface

Re-insert and unplug the GND of the serial port tool

Just wait patiently for the download to complete.

For more functions, please refer to the Beginner’s Guide https://document.chipintelli.com/%E8%BD%AF%E4%BB%B6%E5%BC%80%E5%8F%91/SDK/CI112X%E8%8A% AF%E7%89%87SDK/start/CI112X_SDK_Quick_Start/

exist

Add string output function in uart. and called in the .h file.

In user_config..h, set up as shown in the figure to turn off uart1 redundant output.

And initialize uart1 in the user function

Then we can set the serial port reception interrupt in the microcontroller to implement the corresponding function.

We can also develop SDK to complete our functions.

Because the SDK file is too large, only the main sample file is uploaded! -
