• An audio transcription API is an API that uses algorithms to analyze audio data and transcribe it into text.
• Audio transcription technology is sometimes referred to as Speech-to-text or STT. While both refer to technology that results in audio data transcribed into text data, Speech-to-Text is technically a branch of natural language processing (NLP) that converts spoken language into written text, and is powered by AI models.

• Gladia’s audio transcription API - also called a Speech-to-Text API - allows developers and product owners to add transcription to their products by calling on a single API for every audio transcription need.
