Reading Time: 6 minutes

One of the most difficult challenges in computer science is teaching a computer to understand human language. Although in today’s technological world, speech-to-text looks to be a simple procedure, it takes a number of language models and algorithms to attain near-perfect accuracy Automatic speech recognition (ASR) and machine translation (MT) have made great progress in creating extremely accurate and fluent transcriptions. Amazon Transcribe is an ASR service that allows developers to easily integrate voice-to-text functionality into their apps.

In this blog, we will explore Amazon Transcribe, its features, use cases, Transcribe Call Analytics, Transcribe Medical, its pricing, and the programming languages supported by Amazon Transcribe. We demonstrated the step-by-step instructions on how to add privacy to your transcriptions with Amazon Transcribe to hide all the confidential information from the audio-fetched text in part 2 of the blog.

What is Amazon Transcribe?

Amazon Transcribe makes converting speech to text simple for customers. It can be used for a variety of business applications, including transcription of voice-based customer service calls, generation of subtitles on audio/video content, and conducting a (text-based) content analysis on audio/video content, using Automatic Speech Recognition (ASR) technology.

Any device having an on-device microphone, such as phones, PCs, tablets, and IoT devices, can use Amazon Transcribe. The Amazon Transcribe API will be able to detect the quality of the audio stream being input to the device and will choose the appropriate acoustic models for speech-to-text conversion accordingly. Additionally, developers can use the Transcribe API to access speech-to-text conversion capabilities in their applications.
