An independent Korean technical essay explains speech-to-text fundamentals and traces the shift from HMM and end-to-end ASR pipelines to Whisper, then to 2026-era models including GPT-Transcribe, Qwen3-ASR, and streaming speech models. It argues STT is a whole system rather than a single model, since the microphone only supplies sampled amplitude signals. The article uses Whisper's failure in meeting rooms, where overlapping speech, distant microphones, mixed English abbreviations, and pauses degrade output, as a motivating example. It says 2026 competition has shifted beyond raw transcription accuracy toward real-time behavior, speaker diarization, domain context, hallucination control, security, and operating cost, with on-premises versus API cost trade-offs examined for financial-sector production use.
