What is the purpose of a speech processor in a transceiver?
The correct answer is A: Increase the apparent loudness of transmitted voice signals. The purpose of a speech processor in a transceiver is to increase the apparent loudness of transmitted voice signals. Speech processors compress and level the audio, making your voice sound louder and more consistent. For amateur radio operators, this helps your signal stand out. Understanding this helps when using speech processors.
Exam Tip
Speech processor purpose = increase apparent loudness. Think 'S'peech 'P'rocessor = 'S'ounds 'P'rojected louder. Compresses and levels audio, making voice sound louder and more consistent. Not bass response, not distortion prevention, not high-frequency reduction - just apparent loudness.

"Speech processor purpose = increase apparent loudness. Think 'S'peech 'P'rocessor = 'S'ounds 'P'rojected louder. Compresses and levels audio, making voice sound louder and more consistent. Helps signal stand out."
Real-World Application
You use a speech processor when operating SSB. The processor compresses and levels your audio, making your voice sound louder and more consistent. This helps your signal stand out and be more easily copied, especially in weak signal conditions. Speech processors increase apparent loudness.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. Speech processors don't increase bass response - they process the entire audio spectrum, not just bass. Bass response isn't the purpose.
Option C: Incorrect. Speech processors don't prevent distortion - they can actually cause distortion if overused. Distortion prevention isn't the purpose.
Option D: Incorrect. Speech processors don't decrease high-frequency output - they process the entire spectrum. High-frequency reduction isn't the purpose.
