How Transcription APIs Work

1. Audio Input – The API receives an audio file or live audio stream.
2. Processing – AI-powered speech recognition models analyze the sound, detecting words, phrases, and context.
3. Text Output – The API generates a transcription with timestamps, speaker identification, and optional formatting.
4. Integration – The output is used in business applications, media platforms, chatbots, or content management systems.

Key Features of Transcription APIs

1. High Accuracy – AI-driven models deliver near-human transcription quality.
2. Real-Time and Batch Processing – Supports live speech transcription and processing of recorded audio files.
