Picrawler Edit Voice

Does anyone know how I can edit the voice for picrawler? I am trying to change the voice when doing the Text to speech commands I have edited the prompt of what it says but would like to possibly edit the pitch of the voice or maybe even change it entirely using the samples and just fine tuning it for now.

@SunFounder_Moderator - I would also like to know the answer to this. I know there is a way to do it with Python code, but how would that be implemented through EZBlock?

If you want to use ezblock to control the robot:

  1. You need to download our ezblock OS image system package and extract it.
    Microsoft OneDrive
  2. You need to download the Raspberry Pi Imager tool and use it to flash the custom ezblock OS image system onto the SD card.
  3. Insert the SD card with the flashed ezblock OS into the Raspberry Pi, start the picar-x, and connect via the app.
    When flashing the ezblock OS image system, you can configure the username, password, WiFi name and password, and enable SSH in the Raspberry Pi Imager tool for subsequent remote connection to the picar-x product.

    You can view the tutorial steps in detail.
  4. EZBlock, as a programming tool for Picrawler, supports adjusting parameters through the “Voice Module” or customizing Python code blocks to meet your needs. The steps are as follows:
  5. Adjusting Voice Pitch/Speed ​​(for eSpeak engine)
    If Picrawler uses eSpeak as the TTS engine, you can directly adjust the parameters through the “Text-to-Speech” module in EZBlock:
    Drag the “Text-to-Speech” module to the programming area (usually under the “Sound” category);
    Right-click on the module and select “Edit Parameters” or “Advanced Settings”;
    Find the “Pitch” and “Rate” options:
    Pitch: The default value is usually 100, ranging from 0-200 (the higher the value, the higher the pitch, e.g., 150 is high pitch, 50 is low pitch);
    Rate: The default value is usually 150, ranging from 80-300 (the higher the value, the faster the speech);
    Save the settings and run the project to hear the adjusted voice.

We have example projects with sound effects; please see the online tutorial for details:
