"Planned" walking, as differentiated from "death march" can be really helpful for building endurance, esp. for longer runs, steep hills, and rough terrain. The saying is that if you wait until you have to walk, you've waited too long. Power hiking up a mountain can be an effort just below LT, if you keep it up an hour. Normal walk breaks should be "with purpose" - not a Sunday stroll. If you use extensive walk breaks (technical sections of trail, mountains/hills, etc), practice walking - it uses muscles differently than running.
Some people, esp. on flat, even surfaces, like roads or tracks, do them on planned time intervals (run 9 min, walk 1min; 25/5min, 3/2min, whatever works for you, your training, and your goals). The 25/5 might be used in a 24-hr race by competitive runners since the 5 min gives time for hr to lower and food can be digested.
I use walking mostly for obstacles, snow drifts, steep or big hills, etc. Since I'm on trails most of the time, these usually provide adequate recovery breaks. I'll sometimes add breaks to eat. While I can run and eat at the same time, I've found for longer distances, it's just easier to do the eating during a walk break.
Walking does allow people to run longer, like intervals allow more amounts of higher effort work than what you can do continuously, and it usually reduces recovery time.
Whether it affects your speed depends on your level of training, competitiveness, length of race, etc. Obviously a sprinter or 5k isn't going to gain by walk breaks, but a beginner marathoner
might be faster with walk breaks and it would increase the probability of them making it to the start line uninjured. This is why a lot of people use them.
