WWVH is the Pacific sister station to WWV, and has a similar broadcast format. Like WWV, WWVH's main function is the dissemination of official U.S. Government time, through exactly the same methods as found on WWV's signal.
To minimize interference with the WWV broadcasts on the same frequencies, WWVH's broadcasts on 5, 10 and 15MHz are directional, pointed primarily west. Despite this strategy, in certain places, particularly on the west coast of North America; and at certain times, due to ionospheric conditions, the listener can actually hear both WWV and WWVH on the same frequency at the same time. The information modulated on the carrier is modified to reduce confusion if both are received simultaneously. In particular, voice announcements on one correspond to silent periods on the other.

WWVH Kauai, Hawaii - 1988
A quick tour from 1988 of the "National Bureau of Standards" (NIST) Time and frequency standard shortwave station WWVH on Hawaii's Kauai island, conducted by their chief engineer Nobo Hironaka. See the wacky mechanical/magnetic/cylindrical playback machine for time announcements, and the world-famous Atomic Clock. Plus walls and walls of shortwave transmitters! A treat for xmitter geeks.

WWV = WWVH - Time Signal Identification - Shortwave - 1980's
Different announcers back then. The stations were also part of the National Bureau of Standards, before it became NIST.

WWV And WWVH Time Signals
Comparing reception of WWV and WWVH NIST radio stations from my location and showing how it sounds to receive both at the same time and some of the differences between them.

WWVH audio signal announcement | Signal Phantom
The WWVH audio signal announcement was placed into the NIST time scale to provide a warning in 2018 that congressional action was being considered to cut funding that would have shut off the HF broadcasts of WWV and WWVH while leaving WWVB intact. This idea was short lived due to public pressure mounting given the fact WWV was to celibate 100 years of holding the call sign in October 2019.

Time Signal Stations BPM, WWV, and WWVH, 5000 kHz, January 17 2011, 1528 UTC
Multiple time standard stations heard on 5000 kHz, Chinese BPM, US WWV, and US WWVH.
This recording starts at 1528:38 UTC on January 17, 2011. It is centered on 5000 kHz. Note that at the beginning two sets of time ticks can be heard. The first set is both WWV, Fort Collins, Colorado, USA, and WWVH, Hawaii, USA. The later tick is BPM China. The reason for the two ticks is that from XX25 to XX29 (and XX55 to XX59) BPM sends time syncronized to UT1 instead of UTC. The rest of the time BPM sends syncronized to UTC, so the WWV, WWVH, and BPM time ticks are on top of each other.
Also, starting at 1529 UTC ( 00:30 into this recording ) BPM China starts sending the letter B - P - M in Morse Code. At 1:13 into the recording you can hear IDs start, first is BPM China, next is WWVH Hawa...

I was listening to WWV when i started hearing WWVH as well, and It just happened to be right before The time that they Identify their stations, So i started recording.
Received in Janesville, WI indoors with my Grundig G6 Aviator.
