Speech-to-Text API produces call transcription. It is easier to search and review text history than an audio file. Therefore, transcriptions are widely used by contact center managers in sales and support functions, publishers, students, educators, medical and legal professionals to gain insights and take actions.
From the user's point of view, a speech-to-text system can be categorized based on its use: conversational system, command and control, text dictation, audio document transcription, webinars, interview etc. Each use has specific requirements in terms of latency, memory constraints, vocabulary size, and adaptive features.
