## The Evolution of AI Transcription
12
-
Transcription technology has progressed from simple speech recognition systems to full-blown platforms that handle real-time streaming, multilingual audio, code-switching, speaker-diarization, and deep analytics. Gladia's technology reflects this shift: their engine is designed for live audio, multi-channel, noisy environments, and supports extensive language coverage.
13
-
As voice continues to become a primary interface for human-machine interaction, transcription and audio intelligence are becoming foundational rather than optional.
