Change Release Notes
We're excited to introduce the latest update to Synthiam ARC, packed with new features, enhancements, and bug fixes to elevate your robot-building experience. Let's dive into the details:
1. Fix for 3D Build Instructions with EZbits:
- Users can now seamlessly view 3D build instructions with EZbits without encountering errors related to missing images. Enjoy a smoother building process with this essential fix.
2. Dynamic Assembly and DLL Resolution:
- We've implemented a fix that allows Synthiam ARC to resolve assemblies and DLL files from plugins dynamically. The system will now search and load any assembly that matches the name, even if the versions differ. This enhancement ensures compatibility and flexibility in utilizing various plugins.
3. New Bing Speech Recognition Script:
- Bing Speech Recognition now features a new script that executes as soon as it starts listening. This script allows users to create custom actions, such as displaying LED indicators or animating the robot, to signal that the recognizer is actively listening. Enhance the interaction between users and robots with this exciting addition.
4. Improved UI Rendering Performance:
- Experience a smoother and more responsive user interface with improved rendering performance. This enhancement contributes to a more enjoyable and efficient user experience while working with Synthiam ARC.
5. Instant Recording with Bing Speech Recognition:
- Addressing user feedback, Bing Speech Recognition begins recording spoken audio immediately after playing the wake sound. This eliminates the issue of missing words when users speak quickly to their robots using the wake word. Enjoy a more seamless and accurate interaction with your robot's speech recognition capabilities.
These updates are designed to enhance the functionality, performance, and overall user experience of Synthiam ARC. We appreciate your ongoing support and feedback as we continue to refine and expand the capabilities of our platform. Happy robot building!
