Why is clear enunciation important on a sound-powered line?

• A. Because there is no amplification and the signal is small; clear speech improves intelligibility.
• B. Because the line uses digital encoding that requires exact speech.
• C. Because there is no amplification and the signal is small; clear speech improves intelligibility.
• D. Because listeners prefer slower speech.

Answer: (C)

Clear enunciation matters on a sound-powered line because there is no amplification and the signal is small. Without any power boost, the voice signal can be weakened by line loss, resistance, and ambient noise, so how you shape each word becomes the main factor in whether it’s understood. Speaking clearly—distinct consonants, crisp vowels, and steady pacing—helps the listener pick out the message from the weak signal. This setup isn’t about digital encoding, and while speaking a bit more slowly can help, the core benefit comes from making each word as intelligible as possible so the message can be correctly interpreted without amplification.
