Almost all large airports in the U.S. use the ATIS voice heard in this video, and have been for at least the past 20 years. The voice itself is not nearly as "crisp" and clear as most other large international airports today. Here are examples from Rio de Janeiro and Amsterdam's international airports.
Interestingly, from the research I have done, the voice used in the U.S. comes from a text-to-speech technology called DECtalk launched way back in 1984. The voice used in the ATIS is called "Huge Harry." In other words, this stuff is old technology. Why isn't a more modern voice used?
