In a world where AI is no longer a buzzword but a reality, businesses need to get cozy with technology if they want to thrive. Picture this: your customers engaging in seamless conversations with your brand, just as if they were chatting with a friend. That's the magic of Natural Language Processing (NLP) in Voice AI.
And today’s blog is all about this revolutionary technology. You’ll get to know about its type, its working, various applications, and much more. So without wasting much time let’s dive straight into it.
Here’s what we’ll be covering:
- What is Natural Language Processing (NLP)?
- What Are the Key NLP Categories?
- How Does NLP Work?
- The Top 8 NLP Techniques
- 5 Ways Businesses Are Using NLP-based Voice AI to Elevate CX
What is Natural Language Processing (NLP)?
Alright, let's break it down. What exactly is NLP, and why should you care? Well, NLP is the tech-savvy language whisperer that enables machines to understand and interact with human language. In simpler terms, it's what makes your voice assistants, chatbots, and AI voice bots actually get what you're saying.
Now, let's dive deeper. Imagine you're chatting with a voice bot from your favorite brand. You ask, "Hey, what are the new arrivals?" And the bot, thanks to NLP, instantly knows you're looking for the latest products. But here's the kicker - NLP can take it up a notch by understanding context. So, when you follow up with, "Show me sneakers," it doesn't suddenly start showing you formal shoes. It gets you.
NLP's significance in Voice AI is like the secret sauce that makes your burger irresistible. It’s the heart and soul of conversational AI, powering chatbots, voice assistants, and more. Without it, these tech marvels would be as lost as a GPS without satellite signals.
What Are the Key NLP Categories?
NLP comes in flavors, like your favorite ice cream. Here are the primary categories you should definitely know about:
1. NLU (Natural Language Understanding):
Think of NLU as the brain behind your voice bot. It's what allows it to comprehend your queries. So when you say, "I need a black dress for a party," NLU doesn't just hear "black dress," it understands the occasion and your fashion preferences. It's like having a personal shopper, but cooler.
It deciphers your customer’s messages, understands their intent, and extracts valuable information. With NLU, you're not just hearing words; you're grasping the real meaning behind them.
2. NLP in OCR (Optical Character Recognition):
OCR isn't just about scanning text; it's about turning those scanned words into actionable data. Whether it's extracting data from invoices or processing handwritten forms, NLP in OCR is the unsung hero of data management.
3. NLG (Natural Language Generation):
NLG acts as your virtual writer. It crafts human-like text based on data. So, when you see personalized product recommendations or an AI voice bot's friendly response, you can bet NLG had a hand in it. It's the secret behind those warm, fuzzy feelings you get when interacting with brands.
How Does NLP Work?
According to sproutsocial, 96% of leaders believe AI and ML tools significantly improve decision-making processes. NLP is what powers these tools.
Here’s a simple breakdown of the steps involved in the process:
- Tokenization: Think of tokenization as the NLP's way of turning text into bite-sized pieces. It breaks down the text into smaller units, like words or phrases, called tokens. Imagine it as chopping up a pizza into slices, making it easier to digest.
- Text Cleaning and Preprocessing: Just like you'd tidy up your room before a guest arrives, NLP cleans up the text. It removes irrelevant details such as special characters, punctuations, and upper cases. So, if you ever wondered how NLP understands that "apple" and "Apple" are the same thing, it's because of this cleaning process.
- Part-of-Speech (PoS) Tagging: NLP algorithms put on their grammar hats and start identifying the parts of speech for each token. Is it a noun, verb, or something else? This helps NLP understand the sentence's structure and who's doing what.
- Text Parsing: Now, it's time to dissect sentences. NLP carefully analyzes the grammatical structure to understand the relationships between words. It's like figuring out who's friends with whom in a complex social network.
- Text Classification: Finally, NLP gets into the sorting game. It classifies text into different categories using statistical models. This superpower enables capabilities like sentiment analysis (knowing if you're happy or not) and spam filtering (keeping your inbox clean).
So, when your customer sends a message to a chatbot or a voice bot, it's these behind-the-scenes NLP processes that make sure it understands you correctly.
The Top 8 NLP Techniques
Let's get to the juicy part – the techniques that make NLP shine:
1. Sentiment Analysis:
Ever wondered how brands seem to know if you're thrilled or frustrated? Sentiment analysis reads between the lines of your text to gauge your emotions. So when you rant about a late delivery, the brand knows it's time to make amends.
2. Entity Recognition:
Imagine talking with a travel app’s voice bot, saying, "I want to visit Paris." Named entity recognition (NER) helps it to identify that "Paris" is a place you're interested in. No more confusion about whether you're talking about the city or a person named Paris.
3. Semantic Search:
Ever noticed how search engines seem to know exactly what you're looking for, even when you don't phrase it perfectly? Semantic search is the mastermind behind it. It understands the context of your query via specific keywords and fetches results that make sense. It's like having a mind-reading search engine.
4. Machine Learning:
Machine Learning is like the brainpower of NLP. It learns from data and gets better over time. So, the more you interact with a voice bot, the smarter it becomes at understanding and helping you.
5. Content Suggestions:
NLP powers content suggestions by enabling ML models to contextually understand and generate humanized language in the form of personalized empathetic human-like responses to your customers. It leverages NLU and NLG to do this.
6. Text Summarization:
Have you ever Googled a lengthy article and found a crisp summary at the top? Text summarization does that for your customer conversations. It condenses long text/voice messages into bite-sized summaries, saving you time and effort which can be utilized to do the complex stuff.
7. Machine Translation:
Planning a global expansion? NLP has your back. It can translate languages accurately, making your business truly international. NLP uses many ML tasks such as word embeddings and tokenization to capture the semantic relationships between words and help translation algorithms understand the meaning of words.
A great example would be VoiceGenie’s ability to engage with your customers in more than 100 languages and accents which means your business will never struggle with the hurdle named language barrier.
8. Question Answering:
Imagine having a virtual encyclopedia at your fingertips. NLP can answer your customer’s queries with context, giving them only the most accurate and relevant information in a friendly, conversational manner. One of the most common examples of this application is chatbots.
