Claude Voice Uses Your MCP Servers Now (I Tested It vs ChatGPT)
261 segments
Hey, can you tell me about the latest or
the upcoming call on Monday that I have
from cal.com?
>> Sure, let me pull that up from cal.com
for you.
>> I'm really excited about this. I've been
waiting for this for a long time. We
just got two huge improvements to voice
AI from both OpenAI in ChatGPT and Codex
and Anthropic in Claude. They both work
differently and are better at different
things. I'll explain everything. But
this is something I've personally been
very excited about for a long time
because until now the voice features in
ChatGPT or in Claude can't really do
anything. They can't really use tools.
You can talk to it, you can do a little
web search, but it can't use Connectors,
it can't control things. So I've been
building my own voice AI. I'll show you
that later, but I don't think it's even
relevant anymore because the new version
both OpenAI's version and Anthropic's
versions can now use tools depending on
the platform. And that means we can talk
to our AI and not just dictate. We can
talk, it can use tools, take actions,
and talk back to us. We don't even have
to hit the keyboard anymore. And that's
a huge deal. So first of all, OpenAI
made a huge deal about theirs. They made
a release video essentially bringing
voice back to ChatGPT desktop. But now
instead of ChatGPT desktop, whether it's
regular chat, work, or Codex, you can
have a voice agent that sits with you
and can control and take actions. This
will be very powerful moving forward
where it can actually read back its
responses and even control your
computer. One thing I want to point out
about this, to get it to work, you'll
see this chat icon, different from the
dictation, it will only show up in a
blank chat with no text entered. So hit
this, we see the famous animation, we
say, "Can you play Runaway by Kanye West
on Spotify?"
>> Yeah.
>> So right now it's controlling my
computer and still listening to me.
Let's see. So we're able to get it to
control our computer and play Spotify.
Now that's a very basic example, but
essentially what's going on here is
ChatGPT has computer use access and it
can run its voice agent as an
orchestrator to direct different agents
to do things on your computer. So it's
coding or it's work or it's anything
else. And I know a lot of us have been
using dictation tools like Aqua Voice or
Whisper Flow or Super Whisper or one of
the alternatives and that's really cool.
But being able to talk directly and hear
it talk back and not go back and forth
is really powerful. You can just
imagine. So ChatGPT and got this
advanced live voice on desktop, but
Anthropic did it a bit differently. But,
I just want to point out here, OpenAI
has the best voice model. They have this
real-time, which you can interrupt, it
will still process, and doesn't cut it
off completely. It's a great tool.
Anthropic is essentially the old type of
voice, which is speech-to-text and
text-to-speech. So, you talk, it
transcribes it, it sends it to the
model, it responds, and puts it back in
a voice for you. So, it's a bit slower.
But, Anthropic's release is nicer
because now it can use connectors, it
can use your MCPs in voice mode. They're
saying that the headline is now you can
choose different models. So, before
Claude Voice was using Haiku, their
smallest model. Now, you can choose if
it's Opus, Sonnet, or Haiku. Fable is
not an option, that's probably a good
thing cuz if you're like me, I'm already
at 100% of Fable usage. So, Claude Voice
is only available in chat. You have this
voice icon similar to ChatGPT's. Let me
just show you. First, we're going to use
ChatGPT Voice. I'm going to do it all on
my phone. And the reason we're going to
do that is I want to show you how it has
or doesn't have access to tools. So, I'm
going to open up ChatGPT Voice. Do you
have access to my Gmail?
>> Hang on. And not directly, no. If your
Gmail is connected through a supported
connector in this chat, then I can help.
Otherwise, I can't see your inbox.
>> It's connected to the connector.
>> All right. In that case, I can use it if
it's exposed to me here.
>> It's exposed to you here.
>> Checking. Okay, if it's exposed, the
quickest test is to ask something
specific like, "What's my latest
>> What is my latest email?"
>> Checking now. I can't see your Gmail
from here. The connector isn't actually
available to me in this chat.
>> Trust me, Gmail's connected here. I'm
even going to send it in the same chat.
What's my latest email? It's going to
use the connector. If it's not too
white, you'll be able to see it here.
Essentially, it just shows me my last
email that I sent to myself for this
video. It is a free 10-minute discovery
call between me and someone special.
Now, let's go to Claude. And you're
going to see why I'm so excited about
this. One of the MCPs or connectors I
built was a cal.com MCP. So, I could
have whatever agent I'm using do
research or change or send replies to
people that book calls with me. So, now
we're going to open up Claude on my
phone, and we're going to press the
voice. Hey, can you tell me about the
latest or the upcoming call on Monday
that I have from cal.com.
>> Sure, let me pull that up from cal.com
for you. It's just listed as a free
10-minute discovery call. So, there's no
specific topic attached to it. The only
details I have are that it's with Steve
Rogers at his email steve@avengers.com.
Want me to dig into anything else like
check your email for context on him?
>> Can you do research and tell me who he
is with Bright Data?
>> Sure, let me see what I can dig up on
him through Bright Data. Well, here's
the thing. That name and email are
basically a placeholder. Steve
Rogers@avengers.com
is Captain America. So, either someone
booked with a fake name or it's a test
booking. Uh there's no real person I can
dig up here.
>> So, I'm editing this video as I ride my
indoor bicycle. I realized I didn't do a
one-to-one test, right? So, we're just
going to open up Claude again on my
phone and I'm just going to ask it the
same question I asked ChatGPT.
Can you look at my email and tell me the
last email I got?
>> Sure, let me take a look. Your most
recent email came in today from cal.com.
It's a booking confirmation for a free
10-minute discovery call between you and
Steve Rogers scheduled for Monday, July
27th at 10:45 a.m.
>> So, apples to apples, it was able to use
the same Gmail connector that was
connected to Claude that ChatGPT wasn't
able to use even though it was able to
use it in its text interface. So, the
point is both Claude's new voice mode
and ChatGPT's voice mode have the
ability to take actions. They can
actually do stuff for us. The voice
technology for ChatGPT is a lot better,
but it's only running on your desktop,
only running on the computer for now.
But, Anthropic finally added connectors
or MCP use to their voice mode so that
it can actually take actions from your
voice. So, I don't have to sit at the
computer. I can have it use my
connectors either on the computer or on
my phone when I'm on the go to take
actions, to do research, to tell me
what's going on. And that is huge.
That's something I've been waiting for.
And I'm sure you can imagine all the use
cases where you want to direct your AI
to do something without having to type
on your phone or type on your computer
and just do it by voice. And now that is
possible. And I really believe voice is
the interface of the future for better
or for worse. I know that this will be a
huge productivity unlock and I'm so
happy that both Frontier Labs released
this on the same day. It It not be a new
model or a usage reset, but it's pretty
cool. Now, I just want to show you my
voice model. It's pretty funny. I'm
probably going to take it offline cuz I
won't need it anymore. Essentially, this
is connected to Better Claude. This is
my own personal version of Open Claude
that is running in Claude code on my Mac
mini. I'll link to that video above. I
use my Better Claude every day via
remote control, but what I was really
missing was the ability to talk to it,
similar to what ChatGPT or Claude didn't
have until today. I wanted to be able to
take actions or look at my databases,
look at my schedule, look at my emails.
So, I built it myself. And I modeled it
after ChatGPT's voice where it could
spawn multiple threads. So, I have an
orchestrator running on a small model,
and then it's able to send tasks to
Better Claude. So, let's just see. So, I
have it as a call, right? It's like a
phone call. What's up, man?
>> Not much, just standing by. What's on
your mind?
>> Can you tell me about my latest email?
>> Let me grab that for you. That's a
Netlify bot notification about a PR.
Looks like feedback on an editor
feature. Want me to pull the full thread
on that one? I can have Better Claude
check that for you.
>> So, yeah, basically, I built what I
could build, similar to what OpenAI was
offering. It's speech-to-text to speech
running on my Mac mini where I could
call into it and have it run tasks, have
it do actions. It's obviously slower and
not as efficient as anything that OpenAI
or Anthropic can do. And the creepy
thing is it was using my voice that I
created in my 11 Labs video like a year
ago. So, essentially, I was literally
talking to myself. Super weird. I don't
think I need that anymore. So, yeah, I'm
really into this about this. I like
doing research and getting updates while
I'm walking or on bike rides or driving.
This is huge. The voice interfaces from
OpenAI and Anthropic now have the
ability to take

This video covers the significant advancements in voice AI technology from OpenAI's ChatGPT and Anthropic's Claude. The speaker highlights how these platforms have evolved from simple dictation tools to agents capable of using tools and connectors to perform actions directly. While ChatGPT's voice model is praised for its real-time, fluid interaction capabilities on desktop, Anthropic's Claude voice mode is highlighted for its ability to utilize connectors and MCPs on both desktop and mobile, enabling users to perform research or interact with their emails and schedules on the go. The speaker discusses these developments as a major productivity unlock and concludes by showcasing a personal, custom-built voice AI project that, while functional, is likely now redundant due to these official updates.
