Most of the time, yes.  However, there are instances when the logs are not 
representative of the over-the-air experience.

Common reasons

1. Sampling rate mismatch (44.1 kHz vs. 48 kHz) results in the creepy 
voice syndrome over-the-air, but sounds Ok when played from the web 
page.

2. Audio file retrieval problems results in local text-to-speech 
generator using a different text field or misproununciation

3. Disabling local TTS results in some "silent" IPAWS alerts over the air

4. Misconfiguration of audio chain, typically TV stations, merging 
mono-alert stream with 5.1 audio stream instead of replacing it. I've also 
heard radio stations with mono alerts only on one of the left or right 
stereo channels with program audio on the other channel.

Regularly check the over-the-air EAS result.
