Deepgram is an end-to-end deep learning platform for speech recognition. Unlike the general purpose APIs from Google or Amazon, Deepgram models are custom-trained for each customer. Whether the customer is a call center, a podcasting company, or a sales department, Deepgram can work with them to build something specific to their use case. Sound data

DynamoDB is a managed NoSQL database service from AWS. It is widely used as a transactional database to fulfill key-value and wide-column data models. In a previous show with Rick Houlihan, we explored how to build a data model and optimize the query patterns for a NoSQL database.  Today’s show is about DynamoDB specifically: partitioning,

As a user browses a webpage, that browser session generates events that need to be recorded, validated, enriched, and stored. This data is sometimes called customer data infrastructure, or CDI. This data requires a full stack of different tools: a system on the frontend to collect the data, middleware to transport the data, and backend

A software company manages and interacts with hundreds of APIs. These APIs require testing, performance analysis, authorization management, and release management. In a word, APIs require collaboration. Postman is a system for API collaboration. It allows users to test APIs with collections of requests, monitor the API responses, and visualize the query results. Users of

At a customer service center, thousands of hours of audio are generated. This audio provides a wealth of information to transcribe and analyze. With the additional data of the most successful customer service representatives, machine learning models can be trained to identify which speech patterns are associated with a successful worker. By identifying these speaking
