Personalized Wake-up Response

1. Course Content

• Adding audio files to the muto_llm program's audio library allows you to customize the wake-up voice response.

[!NOTE]

• This section of the tutorial is only for users who need to customize their voice response; it does not affect normal use.

• If you do not need to customize your voice response, you can skip this section.

2. Preparing Audio Files

• You can prepare the audio material for the voice reply yourself.
• Alternatively, you can generate the voice using the system's built-in generate_voice command. The voice generation model uses the Bailian platform's speech synthesis model, so you need to configure ALIBABA_API_KEY according to the tutorial in 02-Configuring API-KEY of this chapter first.
• Pre-configure Bailian API-KEY

• Run the command in the terminal

x
generate_voice --text "hello"

• Where --text is the startup parameter, and "hello" should be replaced with the content of the voice you want to synthesize.

• Audio files 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/
• --text: Text to be synthesized audio, default is empty

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

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