The Synthetic data integration allows you to easily create and manage synthetic data, enhancing your datasets and improving model performance. Whether you need images, speech, or audio data, our new integrations make it simple and efficient.
There is also a video version demonstrating the Synthetic data workflow and features:

​
Supported Blocks

  • DALL-E Image Generation Block: Generate image datasets using Dall·E using the DALL-E model.
  • Whisper Keyword Spotting Generation Block: Generate keyword-spotting datasets using the Whisper model. Ideal for keyword spotting and speech recognition applications.
  • Eleven Labs Sound Generation Block: Generate sound datasets using the Eleven Labs model. Ideal for generating realistic sound effects for various applications.
To use these features, navigate to the Synthetic data tab under the Data acquisition section of Studio.

​
Benefits of Synthetic data management

  • Enhance Your Datasets: Easily augment your datasets with high-quality synthetic data.
  • Improve Model Accuracy: Synthetic data can help fill gaps in your dataset, leading to better model performance.
  • Save Time and Resources: Quickly generate the data you need without the hassle of manual data collection.

​
Accessing the Synthetic data

To access the Synthetic data, follow these steps:
  1. Navigate to Your Project: Open your project in Edge Impulse Studio.
  2. Open Synthetic data Tab: Click on the “Synthetic Data” tab in the left-hand menu.

​
Generating Synthetic Images with GPT-4 (DALL-E)

  • Create Realistic Images: Use DALL-E to generate realistic images for your datasets.
  • Customize Prompts: Tailor the prompts to generate specific types of images suited to your project needs.
  1. Select Image Generation: Choose the GPT-4 (DALL-E) option.
  2. Enter a Prompt: Describe the type of images you need (e.g., “A photo of a factory worker wearing a hard hat”, or some background data for object detection (of cars) “aerial view images of deserted streets”).
  3. Generate and Save: Click “Generate” to create the images. Review and save the generated images to your dataset.

​
Generating Human Speech with Whisper

  • Human-like Speech Data: Utilize Whisper to generate human-like speech data.
  • Versatile Applications: Ideal for voice recognition, command-and-control systems, or any application requiring natural language processing.
  1. Select Speech Generation: Choose the Whisper option.
  2. Enter Text: Provide the text you want to be converted into speech (e.g., “Hello Edge!”).
  3. Generate and Save: Click “Generate” to create the speech data. Review and save the generated audio files.

​
Eleven Labs Sound Effects models

  • Realistic Sound Effects: Use Eleven Labs to generate realistic sound effects for your projects.
  • Customize Sound Prompts: Define the type of sound you need (e.g., “Glass breaking” or “Car engine revving”).

​
Custom synthetic data blocks

If none of the blocks from Edge Impulse fit your needs, you can modify them or develop from scratch to create a custom synthetic data block. This allows you to to integrate your custom generative models for unique project requirements. See the Custom synthetic blocks page for more information.
