Speechmatics Agent STT: API 제공업체 벤치마킹 및 분석
Artificial Analysis 단어 오류율 지수, 속도, 가격을 포함한 성능 지표에서 Speechmatics Agent STT API 제공업체 분석.
주요 내용
API별 Artificial Analysis 단어 오류율(AA-WER) 지수
API별 Artificial Analysis 단어 오류율(AA-WER) 지수
% of words transcribed incorrectly · Lower is better · AA-WER v2 incorporates 3 datasets: AA-AgentTalk (50%), VoxPopuli-Cleaned-AA (25%), Earnings22-Cleaned-AA (25%)
참고: Earnings22에서 시간 제한으로 인해 모델이 전체 길이의 오디오를 안정적으로 처리할 수 없는 경우 약 9분 단위로 분할합니다(해당 모델: Nova 2 Pro, Amazon GPT-4o Transcribe, OpenAI GPT-4o Mini Transcribe, OpenAI). 시간 제한이 더 짧은 모델은 약 30초 단위로 분할합니다(해당 모델: Canary Qwen 2.5B, NVIDIA Inworld STT 1).
