## Описание

Code-switching is how multilingual speakers actually talk and voice-to-text has never kept up. Until now.

In this video, Santiago test's AssemblyAI's Universal-Streaming model, which transcribes six languages (English, Spanish, French, German, Italian, and Portuguese) in real time. No switching keyboards. No language detection delays. Just real-time transcription that handles code-switching naturally.

Watch the switch between English and Spanish mid-sentence and see the model keep up instantly.

I am traveling to Arizona and I want to compare unos and when I get there I want to al so let me show you this because I'm really excited about this. So we're making a ton of progress on AI. Okay, so that's obvious. But one area that I think people will benefit the most is audio applications. Okay. So audio is everywhere from transcription your phone it's you can speak to your phone and dictate to your phone etc etc. Assembly AI just updated their universal model and they can now support listen to this. You can co- switch from six different languages and the model can transcribe that conversation that you're speaking in six different languages in real time in a single forward pass. There is no latency, there are no delays, there is no thinking necessary. The model supports all of these six different languages. I think there is Spanish, uh, English, Italian, French, and German, and Portuguese in real time. This is amazing. Okay, especially if you go to South Florida. Okay. So if you come down here, you will realize very quickly that people have a certain way of speaking. Like I meet new people, friends in my household, right? My family, we sometimes speak mixing two different languages. Sometimes are words that we know how to say in one language and not the other or sometimes are just the full chunks of a sentence. Okay? where you start in one language and then you switch to the uh other language and then come back and it's that's the flow of the conversation. It's a very unique way of speaking but that's how we speak. something that happens to me all the time that I have different friends, friends that speak English, friends uh friends that speak Spanish, friends that speak both of them and it's faster for me to just say the words the way they show up in my brain. So when I I'm trying to express an idea, if it comes in my brain in English, I don't have to translate. I just say it. And if it's in Spanish, If I'm dictating to my uh to my phone because I want to send a text [clears throat] message, something that happens is that I have to go to the keyboard, I have to switch the language so the model that's running here on my phone understands what I'm trying to say. So I have to tell the phone I'm going to be speaking English and then I have to stick to that language to speak English. And probably this is not a problem for 90% of you. It is for me. But if I try to say something in Spanish, it's going to be gibberish here because the phone is trying to translate what I'm saying in Spanish to English. It's not going to transcribe. That transcription is not going to work. This model here does not have that problem. I want to show you an example of it so you can see how it can transcribe in real time. And that is super cool. No delays. I'm going to run this. This is the playground. I'm going to leave a link to this playground so you can try for yourself. Obviously, you can use this model through an API. That's the beauty of it. Like, if you're building an audio application, please try this out. It's super good. So, I'm going to go to streaming. And here in streaming, I'm going to select multi. And this is what's going to allow the code switching from one language to another. And I'm going to start speaking to my computer. I want you to see the speed at which the model is going to transcribe what I'm going to say. Now, I'm going to speak in Spanish and in English and let's see how the model does. Okay. All right. So, let's go. Let's do that. I am traveling to Arizona and I want to that was literally real time. I am traveling to Arizona and I want to buy plane tickets. That's in Spanish. And when I get there, I went back to English. I want to alil rent a car. No delays. Real time code switching between two languages. I want this model on my phone. What do I have to do to get this model to send messages with my phone? This is super cool. I hope you find this helpful. Take a look at the playground and give this a try. Go to their API, Is super good. I

give this a try. Is super good. I hope this is helpful. I'll see you in the next one.
