Personalized Wake-Up Response

1. Course Content

• Add audio files to the multi_brains program's audio library to customize the voice response after wake-up.

[!NOTE]

• This section of the tutorial is only for users who need to customize personalized voice responses and does not affect normal use.
• If you do not need to customize personalized responses, you can skip this section. ## 2. Preparing Audio Files

• The audio materials for voice replies can be downloaded and prepared independently.
• Alternatively, you can generate speech using the system's built-in generate_voice command. The speech generation uses the speech synthesis model from the Bailian platform, so you need to configure the ALIYUN_API_KEY first, as described in the "02 - Configuring API-KEY" section of this chapter.
• Pre-configure the Bailian API-KEY

• Run the command in the terminal:

xxxxxxxxxx
generate_voice --text Hello

• --text is the startup parameter; replace "Hello" with the text you want to synthesize into speech.

• The audio file will be automatically saved in the ~/generate_voices/ directory.

[!NOTE]

Other optional startup parameters are as follows:

• --voice: Speaker, default Cherry
• --language_type: Language, default Chinese
• --save_path: Audio file save path, default ~/generate_voices/
• --config_file: Configuration file path, default ~/M3Pro_ws/multi_brains_file/multi_brains_setting.yaml
• --text: Text to be synthesized into audio, default is empty
• --model: Speech synthesis model, default qwen3-tts-flash

For available speakers and speech synthesis models, please refer to the dynamic notifications on the Bailian official website: https://bailian.console.aliyun.com/?spm=5176.29619931.J_SEsSjsNv72yRuRFS2VknO.2.74cd10d73l2Pw5&tab=doc#/doc/?type=model&url=2879134

• Reference model:

• Reference Tone

• Supported Languages

Chinese, English, Spanish, Russian, Italian, French, Korean, Japanese, German, Portuguese

3. Loading Audio Files

• multi_brains system audio path:

xxxxxxxxxx
~/M3Pro_ws/src/multi_brains/system_vioce

• Where:
• zh is the Chinese response voice, suitable for domestic users. Place the prepared audio files in the directory:

xxxxxxxxxx
~/M3Pro_ws/src/multi_brains/system_vioce/zh/wakeup

• en is the English response voice, suitable for international users. Place the prepared audio files in the directory:

xxxxxxxxxx
~/M3Pro_ws/src/multi_brains/system_vioce/zh/wakeup

• When the multi_brains program is started, it will automatically load the audio files in the corresponding directory and randomly play personalized response voices when the user wakes the system.
