What is Polish speech to text and how does it work?

Speech to text (also called automatic speech recognition, or ASR) converts spoken Polish audio into written text. Deepgram processes the audio signal, detects speech in real time, and returns structured transcript data through an API. Developers use it for applications like voice agents, call analytics, captioning, and searchable media.
