Question:

“What is the procedure for upgrading the Speech Application Programming Interface on an embedded Windows CE system?”

Answer:

Before initiating an upgrade, confirm that your hardware is compatible with the latest version of SAPI. Check the manufacturer’s documentation or contact their support to verify compatibility.

2. Backup Your Data:

Always start with backing up your system and data. This ensures that you can restore the original state if the upgrade process encounters any issues.

3. Review the Documentation:

Microsoft provides detailed documentation for upgrading components like SAPI. Review the [CE Migration FAQ] and [Update Information] to understand the prerequisites and the process.

4. Obtain the Update:

Updates for Windows Embedded Compact 2013, which include SAPI enhancements, are available from Microsoft. You’ll need to access the Device Partner Center (DPC) to download the necessary files.

5. Prepare Your Development Environment:

Ensure that your development environment is set up with the necessary tools, such as Platform Builder and OS Designer, which are part of Microsoft’s Visual Studio.

6. Build the Updated Image:

Using OS Designer, select the appropriate Board Support Package (BSP) for your hardware. If you’re using the Windows CE App Container technology, choose the BSP option for ARM32 or x86 that supports this feature.

7. Test the Update:

Before deploying the update widely, test it on a single device or a controlled group of devices. This helps identify any issues specific to your configuration.

8. Deploy the Update:

Once tested, you can proceed with deploying the update across all devices. This might involve over-the-air updates, physical access to the devices, or other deployment methods suitable for your environment.

9. Validate the Upgrade:

After the upgrade, validate that SAPI is functioning correctly. Test all the features and customizations to ensure they work as expected.

10. Monitor the System:

Keep an eye on the system’s performance and stability post-upgrade. Monitor for any unexpected behavior or issues that might arise.

Remember, the upgrade process can vary based on the specific hardware and software configurations of your embedded system. It’s crucial to follow the guidelines provided by Microsoft and your hardware manufacturer throughout the upgrade process.
