Language Services for AI

Build smarter, intuitive, and interactive applications with language services from AWS

AWS offers a range of machine learning-based language services that allow companies to easily add intelligence to their AI applications through pre-trained APIs for speech, transcription, translation, text analysis, and chatbot functionality. Language services help companies drive positive business outcomes such as improved decision making and enhanced customer service.


Jumpstart Machine Learning

Instead of developing and training your own language models, AWS removes the complexity of building intelligent capabilities into your applications with a simple API call to pre-trained machine learning services.

Accurate & Continuously Learning

The machine learning services constantly learn and improve from a variety of data sources to keep pace with the evolution of language, producing accurate and fluent results for a wide range of use cases.


Cost Effective Way to Scale

With AWS, there are no upfront costs or minimum fees. You are only charged for the text or speech requests that are made. Try any of the language services with the Amazon Free Tier.

Use Cases

Content Discovery & Personalization

Organize and categorize your documents by topic using natural language processing (NLP) for easier discovery in search, and personalize content recommendations for users by delivering other articles related to the same topic. Video transcriptions can also be used to enhance content discovery, an accurate transcript will help search engines detect optimized keywords for a better fit with people’s searches to provide them with the most relevant information.  

Provide a better search experience by enabling your search engine to index key phrases, entities, and sentiment. This enables you to deliver results based on the intent of the search and the context of the content, rather than simply querying an index of keywords. Furthermore, you can generate timestamped transcriptions of video and audio assets to turn them into fully searchable archives, such as finding moments in a video where a particular person spoke certain words. This is applicable to news agencies, educational institutions, broadcasters, content owners, and any other industry that uses audio and video content.

Improve Reach & Accessibility

Add speech, transcription, and translation to content with AWS language services to help facilitate access and participation for everyone, including those with disabilities. Online materials can be read aloud in multiple languages using a wide variety of natural and engaging voices to transform the user’s reading experience. Speech in audio and video content can also be transcribed and translated to provide captioning that improves reach and access.

Data Preprocessing for Advanced Text Analytics

Unlock business value within unstructured data such as emails, social media, and customer voice recordings. By converting audio input into text, Amazon Transcribe lets you build text analytics applications that can search and analyze voice input. And Amazon Comprehend can help facilitate advanced text mining, using natural language processing to establish structure in unstructured text to enable further analysis.

Augment Customer Service

Build intelligent chatbots to engage customers in natural conversations using voice or text. You can also support cross-lingual communications by adding real-time translation to chat, and helpdesk applications to breakdown any language barriers and communicate with customers across the globe.

Gain Customer Insights

Drive new insights into caller sentiment and intent with advanced voice analytics.  Customer contact centers can use Amazon Transcribe and Amazon Translate to turn multilingual voice-based interactions into text, and mine the data for insights using other AWS services like Amazon Comprehend to extract meaning and intent from conversations.
