What is Amazon Lex? (all you must know)
Amazon is the number one choice for digital web services, tailoring cost-effective solutions for the modern business.
If you’re interested in voice technology, you might be wondering: What is Amazon Lex? I was also interested in this service, so I started researching and this is what I found!
What is Amazon Lex in 2022?
Amazon Lex is a web service for building conversational interfaces for text and speech applications in 2022. Lex is part of Amazon Web Services (AWS) and supports the Alexa virtual assistant. Like other Amazon solutions, there are no minimum fees or upfront fees, as pay-as-you-go pricing and a free tier make it an affordable option for conversational interface creation.
Check out the rest of our Amazon Lex guide, including what it does and why it’s a good fit for small and midsize organizations.
What does Amazon Lex do?
Amazon Lex is used to develop conversational engines for speech and text applications.
It’s the same program that supports the Amazon Alexa voice assistant that works with Echo and other smart speaker devices.
This Alexa technology can be used by developers who want to integrate high-tech chatbots into new and existing applications.
Amazon Lex relies on automatic speech recognition (ASR) and natural language understanding (NLU) to engage users with lifelike interactions.
After building, testing, and launching a voice or text chatbot, Lex processes the conversation and automatically adjusts conversation responses
What are the benefits of Amazon Lex?
Released in April 2017, Amazon Lex offers developers the opportunity to create chatbots and other conversational tools for the web, mobile apps, drones, robots, and toys.
One of the greatest strengths of Amazon Lex is its ease of use.
No extensive coding expertise is required – all you need to do is select a conversation flow in the Lex console to generate a bot.
Additionally, Lex technology is perfect for virtual assistants like Amazon Alexa.
It’s separate from the Alexa voice service, which developers use to integrate Alexa with devices like alarm clocks and smart speakers.
While Lex users can interact with Alexa, they can also use chatbot technology with any voice or text interface.
Users can define chatbot responses directly through the Lex section of the AWS Management Console, so chatbots can be built and managed efficiently.
Amazon Lex is also user-friendly. You don’t need a lot of coding knowledge to use this program. As long as you specify the flow of the conversation, Lex does the rest.
With conversation management and tailored responses, Amazon Lex is the first choice for building, testing, and launching chatbots.
You can then add Amazon Lex to Facebook Messenger and other chat platforms.
What can you do with Amazon Lex?
Amazon Lex provides pre-built integrations for AWS Lambda, and it also works with Amazon Cognito, Mobile Hub, DynamoDB, and CloudWatch.
Most developers prefer Lambda integration due to existing enterprise connectors and easy linking to SaaS data like Marketo, HubSpot, and Salesforce.
Amazon Lex and its built-in integrations are a solid choice for advanced security, user authentication, and application development.
Additionally, the pay-as-you-go pricing structure for voice and text requests ensures that Amazon Lex is more affordable than many other programs.
What is an Amazon Lex SLU system?
The Amazon Lex console helps developers quickly create interactive chatbots.
With just a few example phrases, Lex can build natural language models for robot interactions.
Lex bots can ask questions, respond to inquiries, and manage complex tasks.
It’s all part of democratizing deep learning technology that Lex uses to power speech-language understanding (SLU) systems.
This is the same technology used by Amazon Alexa because the SLU system interprets text input and speech to perform functions and fulfill user requests.
Is Amazon Lex expensive?
Not only is Amazon Lex very efficient and easy to use, it’s also cost-effective because you only pay for the services you use.
This means there are no upfront fees or minimum requirements you must meet.
Instead, you only pay for voice or text requests, starting at $0.004 per voice request and $0.00075 per text.
For example, if you have a chatbot that handles 8,000 voice requests and 2,000 text requests in a month, the voice input cost is $32 and the text cost is $1.50.
There’s also a free tier, so you can try Amazon Lex without a full investment. That’s why this AWS product is so popular for building conversational interfaces without breaking your budget.
Additionally, it only takes a few minutes to create a chatbot using this interactive creator, so given the low cost and low time requirements, Amazon Lex is worthwhile for many applications.

Amazon Lex provides web developers with access to the same technology behind the Amazon Alexa voice assistant. Lex is priced on a pay-as-you-go model, so it is a cost-effective option for managing innovative chatbots.
