Core Module Testing Tools

1. Course Content

• multi_brains provides minimal test programs for testing the core modules of a large model, used to quickly locate problems in abnormal situations.

2. Start the Dify service

3. Navigate to the test tool path

cd ~/M3Pro_ws/src/multi_brains/test 
ls

• Test tools are as follows:

4. Test local speech synthesis function

• Test the local speech synthesis function for Chinese and English in sequence

xxxxxxxxxx
python3 test_PiperTTS.py

After running, it will play the Chinese and English speech synthesis results sequentially.

5. Test Local Speech Recognition Functionality

• After running, it will test the preset Chinese and English audio recordings sequentially.

xxxxxxxxxx
python3 test_SenseVoiceSmall.py

After running, it will print the speech recognition results of the test audio.

6. Testing Whether the Robot Can Access Dify Normally

• If the program indicates that the model service is unavailable—and you are unsure whether this is due to an incorrect network address preventing the robot/vehicle system from accessing Dify—you can perform the following test:

xxxxxxxxxx
python3 test_dify_connection.py

If the robot successfully displays the information shown below, it confirms that the connection to Dify is functioning correctly. Otherwise, Dify may not have started, or the Dify program may have crashed and requires a restart.

7. Online Voice Services for Users in Mainland China

7.1 Bailian Speech Recognition (ASR)

• If errors occur with the online speech recognition service, you can independently test the Bailian speech recognition service:

xxxxxxxxxx
python3 test_TongyiASR.py

• Upon execution, the script will perform a speech recognition test using a preset audio sample.

7.2 Bailian Speech Synthesis (TTS)

• If errors occur with the online speech synthesis service, you can independently test the Bailian speech synthesis service:

xxxxxxxxxx
python3 test_TongyiTTS.py

Upon execution, the script will first synthesize speech from a default text sample, and then play the corresponding audio.

7.3 Baidu Qianfan Speech Synthesis (TTS)

• If errors occur while using Baidu's speech synthesis service, you can independently test the Baidu speech synthesis service:

xxxxxxxxxx
python3 test_baiduTTS.py

Upon execution, the script will first synthesize speech from a default text sample, and then play the corresponding audio.

8. Online Voice Services for International Users

8.1 iFLYTEK Speech Recognition Service

• If international users encounter errors with online speech recognition, they can test the iFLYTEK speech recognition service independently.

xxxxxxxxxx
python3 test_xunfeiASR.py

• Upon execution, the script will perform a speech recognition test on a pre-configured test audio file.

8.2 iFLYTEK Speech Synthesis Service

• If international users encounter errors with online speech synthesis, they can test the iFLYTEK speech synthesis service independently.

xxxxxxxxxx
python3 test_xunfeiTTS.py

Upon execution, the script will first synthesize speech from a default text sample, and then play the corresponding audio.
