CPU scheduling determines how Windows allocates processing time to applications. For court reporters and voice writers, low latency and consistent CPU performance are essential for Dragon, Speechmatics, and CAT software. This guide explains how CPU scheduling works and how to maintain optimal performance.

1. Why CPU Scheduling Matters

Windows constantly switches between tasks. If too many background processes compete for CPU time, you may notice:

• Dragon lag or delayed dictation
• Speechmatics latency spikes
• Slow CAT responsiveness
• Audio dropouts
• General system sluggishness

Optimizing CPU scheduling reduces these issues.

2. Foreground vs Background Priority

Windows gives higher priority to the application you are actively using. For court reporters, this means:

• Dragon should be in the foreground during dictation
• CAT software should be in the foreground during realtime
• Speechmatics should run without competing apps

Keeping your primary application active ensures it receives the CPU time it needs.

3. Avoid CPU-Hungry Background Apps

Applications that consume CPU in the background can cause latency. Common offenders include:

• Web browsers with many tabs open
• Cloud syncing apps
• Video conferencing tools
• Gaming launchers
• Security software performing scans

Close or pause these apps during realtime work.

4. Power Mode Affects CPU Scheduling

Windows power modes directly influence CPU behavior:

• Best Power Efficiency slows the CPU and increases latency
• Balanced is acceptable but not ideal for realtime
• Best Performance provides the lowest latency and fastest response

For Dragon and Speechmatics, always use Best Performance.

5. Thermal Throttling and CPU Speed

If the system becomes warm, Windows may reduce CPU speed to protect hardware. This can cause:

• Sudden Dragon lag
• Speechmatics delays
• Slow CAT performance

Ensure your system has proper ventilation and avoid blocking air vents.

6. Real-Time Audio and CPU Latency

Audio processing requires consistent CPU timing. High latency can cause:

• Audio dropouts
• Microphone instability
• Inconsistent recognition

Keeping background processes to a minimum improves audio stability.

7. Restarting Resets CPU Scheduling

Restarting your system clears temporary processes and resets CPU scheduling. For best results:

• Restart daily
• Restart before important realtime sessions

This ensures a clean, stable environment.

8. Symptoms of CPU Scheduling Problems

You may be experiencing CPU-related issues if you notice:

• Dragon lag or delayed dictation
• Speechmatics latency spikes
• Slow CAT responsiveness
• Audio stuttering
• System sluggishness under light load

9. Summary

Close background apps, use Best Performance mode, keep your system cool, and restart regularly.

These steps ensure low latency and smooth performance for Dragon, Speechmatics, and CAT software.
