The efficacy of the computer generated voice

I was just listening to the latest broadcast of severe thunderstorm and tornado warnings rolling in across WXL-37 for upstate NY:

Trouble is a brewing
Trouble is a brewing

It looks a little bit hairy to the north.  There is a lot of rumbling around to the west of us and we are prepared to head for the basement in event of a tornado in this area.

At some point in time, somebody decided that computer generated voices were exactly right for emergency communications. Never mind some of the quirks that can be encountered.  These are mostly pronunciation errors for places like Saugerties, normally spoken as Saw-ger-tees but the NOAA computer voice says S-ouw-jer-tees.  That is understood well enough, but frankly, there are other place names that go by so fast that I cannot make sense of what the computer is saying.

Another good example of this is the Coast Guard’s computer voice confusion around the word “November.”  In the military (NATO) phonetic alphabet, November is the word used to express the letter N.  For some reason, the word itself seems to be a bit of a mystery to the computer, which sometimes renders the word November as “NOVEMBER OSCAR VICTOR ECHO MIKE BRAVO ECHO ROMEO.”  For those of us who have been in the military, this makes perfect sense.  Why just say “November” when you can say much more, waste time, and confuse the unaware.  This particular computer voice is nick named “Iron Mike.”

Computer generated voices can be hit or miss.

Then there is the computer voice from Shannon VOLMET:

Even on HF Single Side Band, that voice is clearly more understandable than the NOAA voices in use today. The issue is, many broadcast stations now use the NOAA computer voice to broadcast weather alerts to their listeners.  If I were driving in my car with lots of background noise, I likely would not get most of the information being relayed by the broadcast station via EAS.  I suppose gone are the days of a professional broadcaster’s voice clearly imparting information and comforting the listeners during time of calamity.  Sigh.

  1. Having the cities of Pulaski, TN, Tupelo, MS and Paducah, KY in our wx area I can empathize. Sven the Drunk Swede butchered almost every town name.

    I worked about 50 contacts Sunday morning of Field Day and had to really work at getting retuned to the SSB sound and QRM. After an hour, it was no trouble to copy even weak stations buried in the QRM but at the start I had to listen closely to copy loud stations.

    Later,

    Could you schedule your times of calamity between 6a-5p Weekdays? Thank you.

    I haven’t had much trouble decoding what the NWS voice is saying, but he does seem to have a midwestern accent that’s possibly been modified by a couple of beers.
    We’re right at home with it. 😉

  3. Chuck, perhaps next time a line of storms comes through I should start drinking so I can better understand the NWS warnings 🙂

  4. Maybe its the shape of the filters and the audio chain but the higher frequency female
    voice seems to be harder to understand on SSB.

  5. I remember when the local NWS stations changed over to the computer generated voice and I agree with Paul that there are many times the intelligibility is something to be desired. It wasn’t all that long again when the CT Department of Transportation removed all human announcers in favor of a text-to-speech system for its traveler’s information service AM transmitters. Sometimes it’s hard to guess which are more difficult to understand.

  6. I stopped listening to NOAA when they ditched the ITC Delta’s and carts and went to the robot speech. Sure, I am sure this saves our money hungry Feds some bucks, but one cannot understand the spoken word being transmitted, what is the point of even having the weather radio service at all?
