1
00:00:00,240 --> 00:00:07,200
Some of you might not be old enough to remember this, but there was a time when

2
00:00:04,080 --> 00:00:09,599
every house had a landline phone with

3
00:00:07,200 --> 00:00:14,240
almost no features at all. Not even a slot to hold extra answering machine

4
00:00:11,440 --> 00:00:18,720
tapes. But while modern smartphones have literally thousands of uses, for all the

5
00:00:17,039 --> 00:00:23,840
ways they've improved on traditional phones, there's one thing that for a

6
00:00:20,880 --> 00:00:29,840
long time they haven't done any better. Actually making phone calls. So, you

7
00:00:26,640 --> 00:00:32,000
chumps who shelled out over $500 for a

8
00:00:29,840 --> 00:00:36,640
flagship smartphone are going to sound like butt when you call your dad to wish

9
00:00:34,160 --> 00:00:41,360
him a happy Father's Day. So, what's the deal with that? Thanks for asking,

10
00:00:39,280 --> 00:00:47,200
Jerry. Here's what happened. Reason number one for shoddy voice quality is

11
00:00:44,360 --> 00:00:51,520
interoperability, which no, it isn't. Which means the powers that be, that is,

12
00:00:49,360 --> 00:00:56,640
phone manufacturers and mobile service providers wanted to make sure that your

13
00:00:54,239 --> 00:01:01,199
shiny new handset could communicate with your sister's old low bandwidth brick

14
00:00:59,039 --> 00:01:05,519
over the network regardless of how they were connected. Number two, and I bet

15
00:01:03,520 --> 00:01:11,520
you college educated viewers saw this one coming, is cost. To put it simply,

16
00:01:08,799 --> 00:01:15,520
upgrading for a clearer voice experience was a lower priority than focusing on

17
00:01:13,920 --> 00:01:19,520
faster data speeds for watching highdefinition video, fewer dead zones

18
00:01:17,840 --> 00:01:23,119
in their service areas, and of course, massive profits to report to the

19
00:01:21,119 --> 00:01:27,360
shareholders. Although, arguably a lot of people would agree with at least the

20
00:01:24,640 --> 00:01:31,600
first two of those things. But you feed people grl for breakfast and Kobe steak

21
00:01:30,000 --> 00:01:34,799
dinner for long enough and they start to ask why they can't have a whipped cream

22
00:01:33,119 --> 00:01:39,360
and strawberry crepe in the morning once in a while. So, while LTE networks were

23
00:01:37,600 --> 00:01:44,400
developed primarily for the purpose of delivering faster data speeds, as

24
00:01:42,079 --> 00:01:49,280
they've become more common, carriers and handset makers have finally begun making

25
00:01:47,360 --> 00:01:54,720
serious progress on a new standard called HD voice. What's that, you ask?

26
00:01:52,799 --> 00:01:59,360
Well, HD voice is a protocol that improves audio quality by capturing more

27
00:01:57,759 --> 00:02:02,799
of what you're saying. I mean, no, I don't mean that your phone had a short

28
00:02:01,119 --> 00:02:08,879
attention span before. What I mean to say is that it can capture a wider range

29
00:02:06,000 --> 00:02:14,720
of frequencies than was possible before. Older phones were good for somewhere in

30
00:02:10,800 --> 00:02:16,400
the range of 300 to 3,400 hertz. But the

31
00:02:14,720 --> 00:02:22,959
human voice can actually make sounds from between 75 hertz and 1,400 hertz. A

32
00:02:21,120 --> 00:02:26,879
huge range that covers the sensual cruning of Barry White all the way to

33
00:02:25,120 --> 00:02:29,280
that horrible squealing noise I make whenever a new gadget arrives in the

34
00:02:28,480 --> 00:02:33,680
mail. HD voice uses the greater bandwidth of

35
00:02:31,680 --> 00:02:38,560
modern cell phone networks to catch everything you say between 50 and 7,000

36
00:02:36,800 --> 00:02:43,440
hertz, making calls sound much more realistic. There's so much blood. This

37
00:02:41,120 --> 00:02:47,840
concept is similar to what you see in digital music recording. So if you're

38
00:02:45,680 --> 00:02:53,840
creating a, you know, wave file, for example, taking more samples of the

39
00:02:50,800 --> 00:02:56,239
singer or instrument as it's playing per

40
00:02:53,840 --> 00:03:01,280
second results in more information ending up in the audio file, which up to

41
00:02:58,800 --> 00:03:05,519
a point means higher perceived quality. So if you're having a conversation over

42
00:03:03,280 --> 00:03:10,720
HD voice, your phone will actually sample your voice 16,000 times per

43
00:03:08,159 --> 00:03:14,560
second, slightly more than FM radio. Here's where it gets funny, though.

44
00:03:12,159 --> 00:03:20,400
Remember those smug pants landline phones from before with their superior

45
00:03:16,800 --> 00:03:22,879
audio quality? Well, to use HD voice,

46
00:03:20,400 --> 00:03:29,519
both you and whomever you're chatting with need to be on devices and networks,

47
00:03:25,760 --> 00:03:31,440
so usually LTE, that support HD voice.

48
00:03:29,519 --> 00:03:35,519
So that call to your dad might sound crappy unless he's got a spanking new

49
00:03:33,680 --> 00:03:39,200
smartphone and a great mobile network anyway. But all of this is normal

50
00:03:37,440 --> 00:03:43,519
growing pains for new technology. And while HD voice isn't universal yet, as

51
00:03:41,760 --> 00:03:48,080
more users switch to new phones and networks, the day may eventually come

52
00:03:46,239 --> 00:03:53,519
when your incoming calls don't sound like they're from Alexander Graham Bell

53
00:03:50,239 --> 00:03:57,799
himself. And no, you didn't, sir.

54
00:03:53,519 --> 00:04:00,480

even say all the things you can learn. You can learn photography. You can learn

66
00:04:42,080 --> 00:04:49,360
business. You can learn things like uh office productivity software. All good
