The primary speech-recognition machine ever was launched by IBM within the distant 12 months of 1962. This machine, referred to as “Shoebox”, wasn’t excellent, but it surely set a basis for the elevated accessibility of computer systems. Within the final decade, this expertise was refined even additional through the use of synthetic intelligence and machine studying within the improvement course of.

Speech-to-text expertise, or speech recognition expertise, has been discovering new methods of implementation previously few years. From digital assistants to healthcare, this expertise has been bettering the lives of many individuals.

On this article, we are going to clarify a few of the key options of this expertise and what are the required elements of speech-to-text expertise.
