Read the text and answer the question below.
Linda and her team are working on a new voice command system for smart homes. The goal is to make it easier for everyone, including people with disabilities, to control devices like lights and doors using their voice.
One challenge is making sure the system understands different accents. The team has been testing the system with users from different regions, but there are still some problems with background noise.
For example, the system sometimes has trouble understanding voices in noisy rooms, like kitchens or living rooms with TVs or radios on. To fix this, they are improving the system's ability to filter out noise and better recognize commands.
Before launching the system, the team plans to gather real-world feedback from users to see how well it works in different home settings. This feedback will help them make the system more accurate and ready for everyone to use.
What is the main challenge the team faces in developing the system?
Adding more features to the system.
The main challenge is ensuring the system works accurately with different accents and background noise.
Improving the visual design.
The challenge is related to voice recognition, not design.
Ensuring the system works well with different accents and background noise.
Reducing the size of the devices.
The paragraph doesn't mention device size as a challenge.
