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

00:00:04.080 --> 00:00:09.599
every house had a landline phone with

00:00:07.200 --> 00:00:14.240
almost no features at all. Not even a slot to hold extra answering machine

00:00:11.440 --> 00:00:18.720
tapes. But while modern smartphones have literally thousands of uses, for all the

00:00:17.039 --> 00:00:23.840
ways they've improved on traditional phones, there's one thing that for a

00:00:20.880 --> 00:00:29.840
long time they haven't done any better. Actually making phone calls. So, you

00:00:26.640 --> 00:00:32.000
chumps who shelled out over $500 for a

00:00:29.840 --> 00:00:36.640
flagship smartphone are going to sound like butt when you call your dad to wish

00:00:34.160 --> 00:00:41.360
him a happy Father's Day. So, what's the deal with that? Thanks for asking,

00:00:39.280 --> 00:00:47.200
Jerry. Here's what happened. Reason number one for shoddy voice quality is

00:00:44.360 --> 00:00:51.520
interoperability, which no, it isn't. Which means the powers that be, that is,

00:00:49.360 --> 00:00:56.640
phone manufacturers and mobile service providers wanted to make sure that your

00:00:54.239 --> 00:01:01.199
shiny new handset could communicate with your sister's old low bandwidth brick

00:00:59.039 --> 00:01:05.519
over the network regardless of how they were connected. Number two, and I bet

00:01:03.520 --> 00:01:11.520
you college educated viewers saw this one coming, is cost. To put it simply,

00:01:08.799 --> 00:01:15.520
upgrading for a clearer voice experience was a lower priority than focusing on

00:01:13.920 --> 00:01:19.520
faster data speeds for watching highdefinition video, fewer dead zones

00:01:17.840 --> 00:01:23.119
in their service areas, and of course, massive profits to report to the

00:01:21.119 --> 00:01:27.360
shareholders. Although, arguably a lot of people would agree with at least the

00:01:24.640 --> 00:01:31.600
first two of those things. But you feed people grl for breakfast and Kobe steak

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

00:01:33.119 --> 00:01:39.360
and strawberry crepe in the morning once in a while. So, while LTE networks were

00:01:37.600 --> 00:01:44.400
developed primarily for the purpose of delivering faster data speeds, as

00:01:42.079 --> 00:01:49.280
they've become more common, carriers and handset makers have finally begun making

00:01:47.360 --> 00:01:54.720
serious progress on a new standard called HD voice. What's that, you ask?

00:01:52.799 --> 00:01:59.360
Well, HD voice is a protocol that improves audio quality by capturing more

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

00:02:01.119 --> 00:02:08.879
attention span before. What I mean to say is that it can capture a wider range

00:02:06.000 --> 00:02:14.720
of frequencies than was possible before. Older phones were good for somewhere in

00:02:10.800 --> 00:02:16.400
the range of 300 to 3,400 hertz. But the

00:02:14.720 --> 00:02:22.959
human voice can actually make sounds from between 75 hertz and 1,400 hertz. A

00:02:21.120 --> 00:02:26.879
huge range that covers the sensual cruning of Barry White all the way to

00:02:25.120 --> 00:02:29.280
that horrible squealing noise I make whenever a new gadget arrives in the

00:02:28.480 --> 00:02:33.680
mail. HD voice uses the greater bandwidth of

00:02:31.680 --> 00:02:38.560
modern cell phone networks to catch everything you say between 50 and 7,000

00:02:36.800 --> 00:02:43.440
hertz, making calls sound much more realistic. There's so much blood. This

00:02:41.120 --> 00:02:47.840
concept is similar to what you see in digital music recording. So if you're

00:02:45.680 --> 00:02:53.840
creating a, you know, wave file, for example, taking more samples of the

00:02:50.800 --> 00:02:56.239
singer or instrument as it's playing per

00:02:53.840 --> 00:03:01.280
second results in more information ending up in the audio file, which up to

00:02:58.800 --> 00:03:05.519
a point means higher perceived quality. So if you're having a conversation over

00:03:03.280 --> 00:03:10.720
HD voice, your phone will actually sample your voice 16,000 times per

00:03:08.159 --> 00:03:14.560
second, slightly more than FM radio. Here's where it gets funny, though.

00:03:12.159 --> 00:03:20.400
Remember those smug pants landline phones from before with their superior

00:03:16.800 --> 00:03:22.879
audio quality? Well, to use HD voice,

00:03:20.400 --> 00:03:29.519
both you and whomever you're chatting with need to be on devices and networks,

00:03:25.760 --> 00:03:31.440
so usually LTE, that support HD voice.

00:03:29.519 --> 00:03:35.519
So that call to your dad might sound crappy unless he's got a spanking new

00:03:33.680 --> 00:03:39.200
smartphone and a great mobile network anyway. But all of this is normal

00:03:37.440 --> 00:03:43.519
growing pains for new technology. And while HD voice isn't universal yet, as

00:03:41.760 --> 00:03:48.080
more users switch to new phones and networks, the day may eventually come

00:03:46.239 --> 00:03:53.519
when your incoming calls don't sound like they're from Alexander Graham Bell

00:03:50.239 --> 00:03:57.799
himself. And no, you didn't, sir.

00:03:53.519 --> 00:04:00.480

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

00:04:42.080 --> 00:04:49.360
business. You can learn things like uh office productivity software. All good
